46,093, THYRISTOR FIRED BY COLLAPSING VOLTAGE ABSTRACT OF THE DISCLOSURE, This invention is concerned with a thyristor device which can be fired by a collapsing voltage. The thyristor is switched from a forward blocking mode to a forward conducting mode when a displacement current produced by a collapsing voltage is concentrated under an auxiliary emitter, thereby causing sufficient carrier emission to fire the device.
