Relay, CPC1231N, LITTELFUSE

A miniature normally closed single-pole solid state relay in a 4-pin SOP package that employs optically coupled MOSFET technology to provide 1500 Vrms of input to output isolation. The optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient infrared LED. The device is compliant with supplementary isolation in accordance with EN/IEC 60950-1. IXYS integrated circuits' state of the art double-molded vertical construction packaging enables it to be one of the world’s smallest 4-pin relays, which offers board space savings approaching 20% over the competitor’s larger 4-pin SOP relay.
