Abstract

1,254,634. Photo-thyristors. ALLMANNA SVENSKA ELEKTRISKA A.B. 25 April, 1969 [26 April, 1968], No. 21157/69. Heading H1K. Firing of a photothyristor having its anode and cathode on opposed faces of the semiconductor wafer is effected by illuminating both faces of the wafer simultaneously. In one embodiment the anode and cathode electrodes are annular and the silicon wafer is illuminated by flashes from a single gallium arsenide light emitting diode or laser which reach the electrode apertures via light pipes consisting of bundles of glass fibres. Alternatively for greater reliability, separate light sources are used to illuminate the anode and cathode sides. In either case a single source may illuminate several devices.
