SIP relay provides up to 4000V input-to-output isolation for high-performance switching

Littelfuse has introduced the CPC1984Y, a 600V, Normally Open Power SIP Relay, rated for up to 1A DC/1Arms continuous load current, twice the load current of the company’s most popular power relay from IXYS Integrated Circuits, now part of the company. This high-reliability device uses optically coupled MOSFET technology to provide 4000Vrms of input-to-output isolation. The SIP Relay provides an excellent combination of load voltage and load current with a 4000Vrms isolation voltage. The optically coupled outputs, which employ the company's ICD patented OptoMOS architecture, are controlled by a highly efficient infrared LED. With a typical on-resistance rating of just 0.51Ohms and a maximum rating of just 0.66Ohms, the device provides particularly lower on-resistance than competitive devices. Its 600V blocking voltage rating provides sufficient design margin for both 110Vrms/220Vrms power line applications for universal power supplies. “The 600V blocking voltage rating and 1A load current handling capability combine to make the CPC1984Y SIP Relay well suited for a variety of high-performance switching applications,” said Mark Heisig, general manager and vice president at IXYS Integrated Circuits Division. “This includes industrial and motor controls, utility meters, instrumentation, medical equipment and home appliances.”
