The XCB170 is a 1-Form-B relay which uses optically coupled MOSFET technology to provide 3750V of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare's patented OptoMOS architecture. A highly efficient GaAIAs infrared LED controls the optically coupled input. The device is available in small 6-pin dual in line package in standard through hole and surface mount lead bend.
