The CPC1030N is a miniature 1-Form-A solid state relay in a 4 pin SOP package that employs optically coupled MOSFET technology to provide 1500V of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare's patented OptoMOS architecture. The optically coupled input is controlled by a highly efficient GaAIAs infrared LED. The CPC1030N uses Clare's state of the art double molded vertical construction packaging to produce the world's smallest relay. The CPC1030N offers board space savings of at least 20% over the competitor's larger 4 pin SOP relay.
