ABSTRACT:
A light triggered thyristor having a light-receiving structure which has a light-receiving surface for receiving incident light on its top surface. The light-receiving structure comprises a base region of a first electrically conductive type exposed in the light-receiving surface, and an emitter region of a second electrically conductive type exposed in a central portion of the light-receiving surface as well as in an area extending from a part of the central portion thereof outwardly beyond the light-receiving surface, and an electrode connected to the base region and the emitter region outside the light-receiving surface, wherein a lateral resistance in the area of the base region between areas underlying the emitter region is aprpoximately equal to or larger than a lateral resistance in the area thereof below the emitter region.
