Solid state relays

The OptoMOS® solid state relays from Littelfuse utilise individual semiconductors and the patented OptoMOS® architecture. This enables fast, reliable and bounce-free switching in a compact design.

The OptoMOS® relays are an ideal replacement for reed relays and smaller electromechanical relays and enable switching with significantly lower drive current.
