ABSTRACT:
An a.c. switch includes across first and second main terminals a first thyristor disposed in parallel with, but in an opposite direction of, a first diode and in series with a second thyristor disposed in parallel with but in an opposite direction of, a second diode. The first thyristor has a gate terminal connected to its gate area. The second thyristor and second diode are vertically realized in the same substrate, their conduction areas being closely interlaced, whereby a polarity inversion following a conduction period of the second diode causes the second thyristor to become conductive.
