Abstract
A bidirectional light-activated thyristor is provided which has a first and a second thyristor portion arranged in inverse-parallel with each other with a predetermined positional relation. The first and second thyristor portions are electrically isolated from each other by an isolating section. The bidirectional light-activated thyristor is provided with a first and a second photo trigger means for triggering the first and second thyristor portions respectively. Means is further provided for blocking a photo-trigger signal from the first photo-trigger means to the second thyristor portion and from the second photo-trigger means to the first thyristor portion.
