Abstract

A gate turn-off thyristor includes a cathode emitter of n-type, a cathode base of p-type, an anode base of n-type and an anode emitter of p-type. A gate electrode is electrically connected to the p cathode base to enclose and define an elemental gate turn-off thyristor region. A plurality of n cathode emitter regions are arranged in proximity to each other in the elemental gate turn-off thyristor region. A highly-doped buried gate region is provided in the p cathode base with the substantially identical configuration for each n cathode emitter regions.
