ABSTRACT:
A solid-state relay is arranged so that, during the off-state of the switching element, a surge protective means forcefully turns the switching element on based upon a surge voltage VSG multiplexed on an AC voltage VAC from output terminals; therefore, a surge current is allowed to flow by the low impedance (on-resistance) of the switching element so that the surge voltage VSG is absorbed to be set to a low surge voltage VSG, thereby making it possible to protect the switching element from damages caused by the surge voltage VSG.
