Description

The CPC1231N is a miniature 1-Form-B solid state relay which uses optically coupled MOSFET technology to provide 1500Vrms of input to output isolation and is certifide for Supplemented Isolation in accordance with EN60950. 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 CPC1231N offers board space savings of at least 20 versus competitive 4 Pin SOP solid state relay.
