Paper Abstract

Light trigger and light quench static induction thyristor (LTLQ-SIThy) is described on the optical triggering and quenching mechanism. The static induction gate structure provides the high turn-on gain. Static induction photo transistor (SIPT) is used for the quenching device. The SIPT gives the high gain of the LTLQ-SIThy at turn-off. This functionally integrated power device provides the high efficiency to switch the large energy. The new LTLQ-SIThy which utilizes the LQ-SIThy for the quenching device is reported. This LTLQ-SIThy improves the switching ability in the large current, the dependency of temperature, and the controllability by the trigger/quench light.
