A light-triggerable thyristor has a semiconductor body which contains an n emitter contacted by a cathode electrode and lying adjacent a p base which, in turn, is adjacent an n base contacting a p emitter having an anode electrode. A projection of the p base extends up to the boundary surface of the semiconductor body adjacent another projection of the n base which likewise extends up to the boundary surface. In order to obtain a high trigger sensitivity, and, at the same time, a high inhibit capability of the thyristor, a light-sensitive element is connected between an electrode which contacts the second-mentioned projection of the n base and the cathode electrode.
