High power static induction thyristor

Two types of static induction thyristors have been developed. The forward blocking voltage and the maximum gate turn-off current of these devices are 800 V, 100 A and 2.5 kV, 500 A, respectively. It has been shown that these devices gave a high forward voltage blocking gain, high current gate turn-off capability, fast gate turn-off speed, high di/dt and dv/dt capabilities and high allowable operating temperature.
