Relay, XAA170S, LITTELFUSE

A dual, normally open solid state relay comprises of two independent, optically coupled relays in a single 8-pin package. Using optically coupled MOSFET technology, it provides 3750 Vrms of input to output isolation. Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient infrared LED. By incorporating two independent single-pole relays into a single 8-pin package, it saves board space by providing a more compact design solution than two discrete single-pole relays in a variety of applications.
