ABSTRACT:
Disclosed is a thyristor and a method for the manufacture thereof. An auxiliary dopant, such as gold, is diffused into the cathode emitter region and the area immediately therearound. The auxiliary dopant is selected from among those known to stimulate charge carrier recombination. Consequently charge carrier recombination in the vicinity of the cathode emitter is enhanced and rapid turnoff of the device is promoted. Both SCR and triac embodiments are disclosed.
