ABSTRACT:
A thyristor comprised of a vertical thyristor including, on its front surface, a localized anode region, and on its rear surface, a cathode metallization substantially coating the whole rear surface region, and, on its front surface region, a lateral thyristor. The thyristor gate corresponds to the cathode region or to the cathode-gate region of the lateral thyristor. The cathode-gate region or cathode region, respectively, of the lateral thyristor is connected to the cathode of the vertical thyristor.
