SITH is also known as ________(a) Field controlled diode(b) Field controlled rectifier(c) Silicon controlled diode(d) Silicon controlled rectifierI got this question during an interview.My question is based upon Power BJTs topic in chapter Differential and Multistage Amplifiers of Electronic Devices & Circuits
Answer» The correct OPTION is (a) Field controlled diode To elaborate: The static induction THYRISTOR (SITHs) is a thyristor with a BURIED gate structure in which the gate electrodes are PLACED in n-base region.They are normally on-state, gate electrodes must be NEGATIVELY biased to hold-off state. It is a self controlled GTO like device. Hence it is sometimes called the field controlled diode.
