The efficient MOSFET switches and photovoltaic die use Clare's patented OptoMOS architecture to provide 3750 VRMS of input to output isolation. The optically coupled input is controlled by highly efficient GaAIAs infrared LEDs. Common input OptoMOS relays can replace standard dual pole relays in a variety of applications. The common input relay eliminates the need to make an external circuit connection when both poles are controlled by a common signal.
