ABSTRACT:
A monolithic semiconductor switch for triggering from a light source or from an electrical signal is provided which includes a light sensitive gate region, and one or more amplifying gate thyristor regions adapted to be connected to an electrical triggering source. Where light triggering is desired, the turn on characteristics of the device are improved by providing light focussing on the light sensitive gate area.
