Static induction thyristor

{{Short description|Type of thyristor device}}

The static induction thyristor (SIT, SITh) is a thyristor with a buried gate structure in which the gate electrodes are placed in n-base region. Since they are normally on-state, gate electrodes must be negatively or anode biased to hold off-state.{{cite book|url=https://www.tib.eu/en/search/id/tema%3ATEMAE96016025009/Study-of-40-A-1000-V-static-induction-thyristor/|title=Study of 40 A / 1000 V static induction thyristor (SITH)|year=1994|volume=1|pages=205–208|author=Li, Siyuan|author2=Liu Su|author3=Yang, Jianhong|author4=Sang, Baosheng|author5=Liu, Ruixi|publisher=International Academic Publishers|location=Beijing, China|isbn=978-7-80003-315-5}} It has low noise, low distortion, high audio frequency power capability. The turn-on and turn-off times are very short, typically 0.25 microseconds.{{cite journal|url=https://hal.archives-ouvertes.fr/jpa-00244534/document|author=J. Nishizawa|author2=K.

History

The first static induction thyristor was invented by Japanese engineer Jun-ichi Nishizawa in 1975.{{Cite book | url=https://books.google.com/books?id=e35kJYAlyCgC&pg=PA231 |title = Electronic Inventions and Discoveries: Electronics from its earliest beginnings to the present day, Fourth Edition|isbn = 9780750304931|last1 = a Drummer|first1 = G. W.|date = January 1997| publisher=CRC Press }} It was capable of conducting large currents with a low forward bias and had a small turn-off time. It had a self controlled gate turn-off thyristor that was commercially available through Tokyo Electric Co. (now Toyo Engineering Corporation) in 1988. The initial device consisted of a p+nn+ diode and a buried p+ grid.{{cn|date=September 2023}}

In 1999, an analytical model of the SITh was developed for the PSPICE circuit simulator.{{cite journal|author=J. Wang|author2=B.W.
