ABSTRACT:
Disclosed is a bidirectional light-activated thyristor which comprises a first and a second thyristor portion arranged in inverse-parallel with each other with a predetermined positional relation, an isolation section for electrically isolating the first and second thyristor portions from each other, a first and a second main electrode for connecting the first and second thyristor portions with each other in inverse-parallel, and a first and a second photo-trigger means for triggering the first and second thyristor portions respectively, wherein the photo-trigger signal from the first photo-trigger means is prevented by the first thyristor portion from reaching the second thyristor portion and the photo-trigger signal from the second photo-trigger means is prevented by the second thyristor portion from reaching the first thyristor portion.
