Abstract
A thyristor for low-loss triggering of short impulses, including a main thyristor formed of four alternating zones of opposite conductivity type including a cathode emitter, a cathode base, an anode base and an anode, with a portion of the cathode base emerging to a cathode-side surface and serving as a gate; an integrated auxiliary thyristor provided for improving current rise time upon main thyristor ignition between the gate and the cathode emitter of the main thyristor; and an integrated diode provided for shortening the turn-off time of the main thyristor when ending current conduction therethrough; wherein the integrated diode is implemented as a Schottky contact which injects virtually no electrons into the cathode base under normal operating conditions.
