ABSTRACT:
Power thyristor having rapid triggering, comprising a triggering emitter. the cathode face, the separation line between an intermediate zone of the base and the main emitter, a line from which the firing of the thyristor is effected, has a symmetrical corrugated shape allowing an interdigitation which is also symmetrical. Application to the increasing of the triggering speed of power thyristors without any noticeable reduction in the maximum value of the intensity.
