ABSTRACT:
A light-activated semiconductor-controlled rectifier device comprising four layers of PNPN is disclosed in which a part of the edges of the PN junction formed between the intermediate P-type layer and the intermediate N-type layer is exposed on the same side on which the outer P-type layer is exposed, so that a photo-trigger signal is radiated on that exposed part of the edges of the PN junction.
