OptoMOS® power relays serve as highly reliable dc switches in electric motors, flow meters, medical equipment, robotics, and vehicles. The integrated circuits made by Littelfuse subsidiary IXYS consist of LED-controlled semiconductors and MOSFETs. Using the normally open (Form A) relays with heat sinks boosts load current handling capabilities. Consult the Littelfuse Integrated Circuits Selection Guide to identify the best relay for your application.
