Abstract
A thyristor device comprising an SI (Static induction) thyristor or beam base thyristor and an SIT (static induction transistor) or SIT-mode bipolar transistor connected to the gate of the thyristor in order to make it possible to turn-on and-off a direct current and voltage at a high speed with a light. In the thyristor part, the SIT gate structure or SIT-mode beam base structure exists in the first gate or base region or second gate or base region so that, at the time of the triggering operation, a very high switching efficiency will be obtained.
