Abstract
The present invention is directed to a thyristor comprising a body of semiconductor material with at least four zones of alternating conductivity type, of which the first zone represents an emitter zone and is provided with an emitter electrode, a second zone adjacent said first zone represents a base zone and is provided with an electrode, with at least one pn junction between the emitter zone and the base zone, and with at least one shunt bridging the pn junctions, this shunt being a current path located in the base zone or in the emitter zone, uninterrupted by any pn junction, located on the surface of the semiconductor body, and directly connecting the emitter electrode and the base electrode.
