Emitter and Collector have to be exchanged - otherwise the internal devices make no sense since source and collector are connected. Thus the resistor "body region" in the equivalent circuit does not make sense either. It would be the resistance of the ohmic contact shorting FET-Source and BJT-Collector. As a consequence the parasitic transistor will be mainly "off" since the voltage drop is quite low. <a href="/wiki/Special:Contributions/130.149.57.205" title="Special:Contributions/130.149.57.205">130.149.57.205</a> (<a href="/w/index.php?title=User_talk:130.149.57.205&action=edit&redlink=1" class="new" title="User talk:130.149.57.205 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-130.149.57.205-2010-11-11T10:51:00.000Z-Miscellaneous" class="ext-discussiontools-init-timestamplink">10:51, 11 November 2010 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-130.149.57.205-2010-11-11T10:51:00.000Z-Miscellaneous"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-130.149.57.205-2010-11-11T10:51:00.000Z-Miscellaneous"></span> </p><p><span data-mw-comment-start="" id="c-Mtodorov_69-2006-03-10T13:59:00.000Z-Miscellaneous"></span>It is not clear how it works, and what this N+ ares under the insulator are standing for? </p><p>A better explanation is required, such as down to level of PN barriers, what opens and what shuts when the device is open and when it is closed. </p><p>Otherwise, good work -- <a href="/wiki/User:Mtodorov_69" title="User:Mtodorov 69">Mtodorov 69</a> <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-Mtodorov_69-2006-03-10T13:59:00.000Z-Miscellaneous" class="ext-discussiontools-init-timestamplink">13:59, 10 March 2006 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-Mtodorov_69-2006-03-10T13:59:00.000Z-Miscellaneous"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-Mtodorov_69-2006-03-10T13:59:00.000Z-Miscellaneous"></span> </p> <dl><dd><span data-mw-comment-start="" id="c-CyrilB-2006-03-10T16:08:00.000Z-Mtodorov_69-2006-03-10T13:59:00.000Z"></span>I agree this page deserve more.

This means that unlike a MOSFET, IGBTs cannot conduct in the reverse direction. In bridge circuits where reverse current flow is needed an additional diode (called a freewheeling diode) is placed in parallel with the IGBT to conduct current in the opposite direction. The penalty isn't as severe as first assumed though, because at the higher voltages where IGBT usage dominates, discrete diodes are of significantly higher performance than the body diode of a MOSFET."

Through our internal discussions and surveys about the IGBT history, we found the wikipedia descriptions on IGBT are not correctly reflecting the facts. So I simply tried to correct it. I edited the IGBT article based on the facts. If possible, I'd like to make another modification. We found one Japanese patent (Shouwa47-21739 filed in 1968 by Yamagami) disclosing IGBT structure earlier than the patent by Becke. These are just facts.

Your improvements are appreciated, but you need to be careful about biasing the history too much one way, or adding your own opinions of relative importance. For example, you interpretation "the patent provided only the concept of IGBT and did not provide any concrete means to realize actual devices" needs a source, or needs to be removed. Similarly "it was found that the products from GE still suffered from the latch-up of the parasitic thyristor." You sound very partisan in these edits, trying to reduce credit to one set of inventors and add volumes on another. Please try to keep a more balanced perspective, supported by sources; facts are great, but your interpretations need to be omitted, or at least moderate and balanced. Also, tell us more about your background, affiliation, and the book you are writing, if you want us to understand where you are coming from. If you work with Nakagawa or his organization, we should know that, so that we can provide the balance against your viewpoint. You can use the "history" button to get back to your most recent version and make improvements from there. <a href="/wiki/User:Dicklyon" title="User:Dicklyon">Dicklyon</a> (<a href="/wiki/User_talk:Dicklyon" title="User talk:Dicklyon">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-Dicklyon-2008-03-28T18:48:00.000Z-Nca01634-2008-03-28T11:46:00.000Z" class="ext-discussiontools-init-timestamplink">18:48, 28 March 2008 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-Dicklyon-2008-03-28T18:48:00.000Z-Nca01634-2008-03-28T11:46:00.000Z"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-Dicklyon-2008-03-28T18:48:00.000Z-Nca01634-2008-03-28T11:46:00.000Z"></span></dd></dl></dd></dl> <dl><dd><dl><dd><dl><dd><span data-mw-comment-start="" id="c-Nca01634-2008-03-29T00:28:00.000Z-Dicklyon-2008-03-28T18:48:00.000Z"></span>I understand and agree with your opinion. However, as far as I know, at least three independent Japanese companies tested GE's IGBTs around 1984 and found they were easily destroyed by the latch-up of the parasitic thyristor. This is also the facts. Yes, I need good reference for the facts. I have only three testifiers but do not have a good reference. Regarding the Becke's patent, it substantially claims the non-latch-up opearation for the entire device operation condition in the first claim: "no thyristor action occurs under any device operating conditions." It does not provide any concrete device structures to achieve this (probably, this is my opinion.)</dd> <dd>I have to add two important references about IGBTs. These are Yamagami's patent filed in 1968(can be found by using the data base <a rel="nofollow" class="external free" href="http://www4.ipdl.inpit.go.jp/Tokujitu/tjsogodben.ipdl?N0000=115">http://www4.ipdl.inpit.go.jp/Tokujitu/tjsogodben.ipdl?N0000=115</a> by inputting "Kind code" B, "Number" S47-21739) and and Prof. Plummer's patent Re33209, which is reissue of US patent 4199774 filed in 1978. These are probably earlier than Baliga's patent filing and Becke's patent, but still controversial. The descriptions regarding Prof. Baliga are the facts and I did not make any changes.</dd> <dd>Thank you for your precious comments.

Baliga and Plummer found IGBT mode operation in a thyristor(SCR) before 1980. However, the device operated in the IGBT mode only for a lower current level, and in the thyristor mode for a larger current level. Yamagami proposed, in 1968, a monolithic vertical four layer device where the pnp transistor is controlled by the n-channel MOSFET, which is the same structure as IGBT. He did not discuss the latch-up of the parasitic thyristor.<a href="/w/index.php?title=User:Nca01634&action=edit&redlink=1" class="new" title="User:Nca01634 (page does not exist)">Nca01634</a> (<a href="/wiki/User_talk:Nca01634" title="User talk:Nca01634">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-Nca01634-2008-03-29T12:11:00.000Z-It_is_controversial_who_the_real_inventor_of_IGBT_is!!!" class="ext-discussiontools-init-timestamplink">12:11, 29 March 2008 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-Nca01634-2008-03-29T12:11:00.000Z-It_is_controversial_who_the_real_inventor_of_IGBT_is!!!"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-Nca01634-2008-03-29T12:11:00.000Z-It_is_controversial_who_the_real_inventor_of_IGBT_is!!!"></span> </p> <dl><dd><span data-mw-comment-start="" id="c-Dicklyon-2008-03-29T16:42:00.000Z-Nca01634-2008-03-29T12:11:00.000Z"></span>So put all that into the article, with sources. What we want to avoid is including statements like "it is controversial" unless we can find a reliable source that discusses such a controversy. And if inventorship or priority is unclear, we should avoid making any claims about inventorship or priority. Just listing who did what when, with sources, is the way to keep the viewpoint neutral. There's no need to presume a concept such as "real inventor" or to make up a controversy if that's not what's out there.

</p><p>Unfortunately until now the NPT-Variant ist not yet mentioned in the article. </p><p>In the German counterpart it is said: "Im Gegensatz zu Leistungs-MOSFETs können Punch-Through-IGBTs (PT-IGBT) zur Erhöhung der Stromtragfähigkeit nicht ohne weiteres parallel geschaltet werden. Non-Punch-Through-IGBTs (NPT-IGBT) hingegen besitzen wie die Leistungs-MOSFETs einen positiven Temperaturkoeffizienten und können parallel geschaltet werden. In den meisten IGBT-Hochleistungsmodulen wird das auch getan." </p><p>This roghtly translates to: "Unlike power MOSFETs, Punch-Through-IGBTs (PT-IGBT) can not be connected in parallel easily to increase the current carrying capacity. Non-Punch-Through IGBT (NPT-IGBT), however, have a positive temperature coefficient like power MOSFETs and therefore can be connected in parallel. In most IGBT high power modules this is done." </p><p>Maybe someone with knowledge about the technical terms can fit this into the article. </p><p>And I suggest to use the first picture of the German article as well. <a href="/wiki/User:Manorainjan" title="User:Manorainjan">Manorainjan</a> (<a href="/wiki/User_talk:Manorainjan" title="User talk:Manorainjan">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-Manorainjan-2014-12-22T20:59:00.000Z-Non-Punch-Through-IGBT" class="ext-discussiontools-init-timestamplink">20:59, 22 December 2014 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-Manorainjan-2014-12-22T20:59:00.000Z-Non-Punch-Through-IGBT"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-Manorainjan-2014-12-22T20:59:00.000Z-Non-Punch-Through-IGBT"></span> </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Symbol" data-mw-thread-id="h-Symbol-2016-04-28T21:17:00.000Z"><span data-mw-comment-start="" id="h-Symbol-2016-04-28T21:17:00.000Z"></span>Symbol<span data-mw-comment-end="h-Symbol-2016-04-28T21:17:00.000Z"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Talk:Insulated-gate_bipolar_transistor&action=edit&section=20" title="Edit section: Symbol"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata"></div><div class="ext-discussiontools-init-section-actions"></div></div></div> <p><span data-mw-comment-start="" id="c-Arghman-2016-04-28T21:17:00.000Z-Symbol"></span>Please add the IGBT symbol <a href="/w/index.php?title=User:Arghman&action=edit&redlink=1" class="new" title="User:Arghman (page does not exist)">Arghman</a> (<a href="/wiki/User_talk:Arghman" title="User talk:Arghman">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-Arghman-2016-04-28T21:17:00.000Z-Symbol" class="ext-discussiontools-init-timestamplink">21:17, 28 April 2016 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-Arghman-2016-04-28T21:17:00.000Z-Symbol"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-Arghman-2016-04-28T21:17:00.000Z-Symbol"></span> </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Beyond_IGBT?" data-mw-thread-id="h-Beyond_IGBT?-2016-01-23T21:56:00.000Z"><span id="Beyond_IGBT.3F"></span><span data-mw-comment-start="" id="h-Beyond_IGBT?-2016-01-23T21:56:00.000Z"></span>Beyond IGBT?<span data-mw-comment-end="h-Beyond_IGBT?-2016-01-23T21:56:00.000Z"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Talk:Insulated-gate_bipolar_transistor&action=edit&section=21" title="Edit section: Beyond IGBT?"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata"></div><div class="ext-discussiontools-init-section-actions"></div></div></div> <p><span data-mw-comment-start="" id="c-87.97.103.13-2016-01-23T21:56:00.000Z-Beyond_IGBT?"></span>The article could discuss if there is anything visible or theorized to come up, beyond IGBT? Many people now think the most modern IGBT generation is the end of the journey, the sorcerers' stone found as far as semicondutor based power electronics goes and nothing futher revolutionary but only very gradual progress can be expected. (Just like how silicon-based ICs stayed with us for over almost 50 years and Intel's latest 14nm is essentially the end of the journey started by the 4004/8088, a further revolution never happened.) <a href="/wiki/Special:Contributions/87.97.103.13" title="Special:Contributions/87.97.103.13">87.97.103.13</a> (<a href="/w/index.php?title=User_talk:87.97.103.13&action=edit&redlink=1" class="new" title="User talk:87.97.103.13 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-87.97.103.13-2016-01-23T21:56:00.000Z-Beyond_IGBT?" class="ext-discussiontools-init-timestamplink">21:56, 23 January 2016 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-87.97.103.13-2016-01-23T21:56:00.000Z-Beyond_IGBT?"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-87.97.103.13-2016-01-23T21:56:00.000Z-Beyond_IGBT?"></span> </p> <dl><dd><span data-mw-comment-start="" id="c-87.97.103.13-2016-01-23T22:38:00.000Z-87.97.103.13-2016-01-23T21:56:00.000Z"></span>Indeed, it would seem that IGBT is the end of the journey, at least for our generation. The int'l railway federation (UIC) states:</dd> <dd></dd> <dd><a rel="nofollow" class="external free" href="http://www.railway-energy.org/static/IGBT_28.php">http://www.railway-energy.org/static/IGBT_28.php</a></dd> <dd>--> At present, no innovations in power electronic replacing IGBTs are close to market stage, not even in the low-power segment (which is usually an early monitor for later developments in the power segments relevant for railway applications). <--</dd> <dd>- IGBTs have reached maturity and only peripheral R&D remains to be done in this field, like: raise blocking voltages, increase switching frequency,reduce losses,reduce weight, optimize circuits and cooling.</dd> <dd>Furthermore:</dd> <dd>- JR Hokkaido railway company claims IGBT controlled 3-phase AC motors reduce environmental train noise by 10% compared to their GTO counterpart. [Important issue in small and crowded Japan, e.g. the FASTECH360 shinkansen experiment failed due to noise pollution!]</dd> <dd>- JR Hokkaido also claim IGBT controlled 3-phase AC motors save 15% energy compared to their GTO predecessors.</dd> <dd>- IGBTs can now operate at >1000A at 3-4x higher switching frequency than GTO and such high switching frequencies smoothen the trains' acceleration process.</dd> <dd>- IGBT modules are generally lighter than GTO modules by some 30%. This offers constructive advantages for vehicles.</dd> <dd>- Compared to GTO less cooling is required for IGBT and no organic coolants are required)</dd> <dd>- Due to IGBT advances, GTO is now out of picture up to 7MW for newly built railway prime movers and MU.</dd> <dd>( Extra points: nowadays even 300USD household washing machines are run by 3-phase AC motor with DSP-controlled IGBT supply. The low-end market thus has been conquered just as the superexpress field.

I just realised the same thing, and upon reading through this talk page I notice that this was reported already in 2010, in the very first talk page section "Miscellaneous". Apparently nobody reacted to that then… My understanding is that the labels "emitter" and "collector" should be switched, but it could be some convention which makes sense to people more familiar with these devices (e.g. control voltage is that between gate and other top connector, which is why people think of it as "emitter"). In that case, the article should explain why terminology is the way it is. <a href="/wiki/Special:Contributions/37.2.59.8" title="Special:Contributions/37.2.59.8">37.2.59.8</a> (<a href="/w/index.php?title=User_talk:37.2.59.8&action=edit&redlink=1" class="new" title="User talk:37.2.59.8 (page does not exist)">talk</a>) <a href="https://en.wikipedia.org/wiki/Talk:Insulated-gate_bipolar_transistor#c-37.2.59.8-20230117231200-LachlanA-20221230043800" class="ext-discussiontools-init-timestamplink">23:12, 17 January 2023 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-37.2.59.8-20230117231200-LachlanA-20221230043800"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-37.2.59.8-20230117231200-LachlanA-20221230043800"></span></dd></dl>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://en.wikipedia.org/w/index.php?title=Talk:Insulated-gate_bipolar_transistor&oldid=1202966269">https://en.wikipedia.org/w/index.php?title=Talk:Insulated-gate_bipolar_transistor&oldid=1202966269</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Help:Category" title="Help:Category">Categories</a>: <ul><li><a href="/wiki/Category:B-Class_electronic_articles" title="Category:B-Class electronic articles">B-Class electronic articles</a></li><li><a href="/wiki/Category:Mid-importance_electronic_articles" title="Category:Mid-importance electronic articles">Mid-importance electronic articles</a></li><li><a href="/wiki/Category:WikiProject_Electronics_articles" title="Category:WikiProject Electronics articles">WikiProject Electronics articles</a></li></ul></div><div id="mw-hidden-catlinks" class="mw-hidden-catlinks mw-hidden-cats-hidden">Hidden category: <ul><li><a href="/wiki/Category:Pages_with_missing_files" title="Category:Pages with missing files">Pages with missing files</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> This page was last edited on 3 February 2024, at 22:52<span class="anonymous-show"> (UTC)</span>.</li> <li id="footer-info-copyright">Text is available under the <a href="/wiki/Wikipedia:Text_of_the_Creative_Commons_Attribution-ShareAlike_4.0_International_License" title="Wikipedia:Text of the Creative Commons Attribution-ShareAlike 4.0 International License">Creative Commons Attribution-ShareAlike 4.0 License</a>; additional terms may apply.
