Solid State Relays

OptoMOS^® solid state relays enable fast, reliable, and bounce-free current switching electrical systems using alternating current and carrying high loads. Littelfuse offers these semiconductor-based relays in compact designs suitable for mounting on printed circuit boards and requiring minimal heat sinking. Our solid state relays make ideal replacements for reed relays and electromechanical relays.
