The efficient MOSFET switches and photovoltaic die use Clare’s patented OptoMOS architecture. The optically-coupled input is controlled by a highly efficent GaAIAs infrared LED. The LCA712 can be used to replace mechanical relays and offers the superior reliability associated with semiconductor devices. Because they have no moving parts, they can offer faster, bounce-free switching in a more compact surface mount or through hole package.
