ABSTRACT:
An amplifying-gate thyristor having an increased integrated circuit includes a main thyristor and an amplifying thyristor. The amplifying thyristor is of the gate turnoff-type. The main tbyristor and the amplifying thyristor are such that the amplifying thyristor remains in the conductive state while the main thyristor is conductive. A control circuit turns off the amplifying thyristor when the current through the main thyristor is approximately its hold current.
