Talk:Silicon controlled rectifier

message: I'm reverting part of the edit made 14:16, 11 July 2012 by 63.87.61.59.  That IP user seems to be a well-meaning vandal per the users' talk page, and for some reason changed Gordon Hall's name to Robert Hall, probably because Robert was an EE working on rectifiers at GE at the time, and already had a Wikipedia page that could be linked to.  Gordon Hall is my uncle.  I do need to dig up the patent number and cite it here.  There is some language at https://sites.google.com/site/transistorhistory/Home/us-semiconductor-manufacturers/general-electric-history which mentions Gordon and the SCR development in particular, but most of that page is about Robert, which just adds to the confusion.  Bill Gutzwiller's oral history at 
http://www.semiconductormuseum.com/Transistors/GE/OralHistories/Gutzwiller/Gutzwiller_Page6.htm describes Gordon's involvement in more detail.  For now I'll cite the latter in the main article.

message: An SCR is not a diode, as the erroneous definition that was added stated.  They are neither functionally nor physically similar.  An SCR when it is defined in terms of equivelant components is always defined as two BJT transistors.  The two devices have nothing in common except that they are both multi-layer semiconductor devices.  In this respect they differ in the number of layers, so that if you consider an SCR a diode, then a microprocessor is also a diode.  In both cases using the device in nonstandard configurations can make them perform as a diode, but this is not typical or correct and will likely damage the SCR. AQBachler 15:25, 26 Nov 2003 (UTC)

message: I think we should probably replace this article with a REDIRECT to the much-more-extensive article at Thyristor. How do folks feel about this?

replies: text: this page used to be a redirect (up until recently) to Thyristor.  I think part of the difficulty was that some references define SCR and Thyristors as the same, while others don't. I'm ok with combining articles, might want to get imput from the persons who delt with this before. (see article history). Duk 16:49, 25 Feb 2005 (UTC)

text: While it is true that the terms SCR and thyristor are sometimes used synonymously, an SCR is a subset of the overall classification of thyristors. Other such types of thyristors are the GTO, MCT, the triac. It would not make sense to refer to, for example, refer to the GTO as a type of SCR. The common link for thyristors is that they are bistable devices with a pulsed gate requirement that turn on by pnpn regeneration. The SCR does not have a "controlled" turn off; the GTO does.Mak17f 23:13, 2 January 2006 (UTC)
replies: text: Not all thyristors are SCRs - an SCR only conducts in one direction, but thyristors such as the triac will conduct in either direction. I checked with IEEE Std. 100 and they call the SCR a synonym for "reverse blocking thyristor". --Wtshymanski 18:58, 10 January 2006 (UTC)
replies: text: Not all SCRs are made of Silicon either!  The development of thyristors made from Silicon carbide has led some people to use the acronymn SCR to denote Semiconductor Controlled Rectifier. DFH 16:02, 7 May 2006 (UTC)

text: When referring to latchup in CMOS circuits, sources usually refer to parasitic thyristors, and hardly ever to parasitic SCRs. DFH 16:12, 7 May 2006 (UTC)

message: Why "Silicon controlled rectifier" redirects here, and not the other way around? SCR is a {Silicon {controlled {rectifier}}}: "controlled rectifier made of silicon", not a {{Silicon-controlled} {rectifier}}: "rectifier controlled by silicon". -- Mikhail Ryazanov (talk) 04:23, 21 March 2011 (UTC)
thread_title:  Article name 

message: Silicon controlled makes no sense to me as a name.  The device is in fact a semi-conductor rectifier.  I am familiar with the term SCR from numerous industrial projects I worked on and knew what the device did, although not my field of specialty.Phmoreno (talk) 01:50, 25 January 2012 (UTC)
