Low-loss high speed switching device, 2500 V-300 A static induction thyristor

An anode-emitter-shorted type 2500 V-300 A buried-gate static induction thyristor is fabricated. Results indicate a very high speed turn-on time of 2.0 microsec and turn-off time of 3.1 microsec, both at 1000 A. The switching-loss and conduction-loss of the high power static induction thyristor are evaluated for the first time in this paper. The snubber-circuit-less operation is first demonstrated for the high power static induction thyristor.
