Littelfuse has introduced CPC1984Y, a 600V, normally-open power SIP relay rated for a continuous load current of 1A DC / 1Arms, which is twice the load current of the company's most popular power relay from IXYS Integrated Circuits. This high-reliability device employs photo-coupled MOSFET technology and provides 4000Vrms input-to-output isolation. The SIP relay perfectly combines load voltage and load current with 4000Vrms isolation voltage. The optical coupling output using the company's patented OptoMOS architecture is controlled by a highly efficient infrared LED.
The device has a typical on-resistance rating of only 0.51 Ohms and a maximum rated on-resistance of only 0.66 Ohms. Compared with similar devices, its on-resistance is particularly low. Its 600V blocking voltage rating provides sufficient design margin for 110Vrms / 220Vrms power line applications for universal power supplies.
Mark Heisig, general manager and vice president of IXYS IC Division, said: "The combination of a 600V blocking voltage rating and a load current handling capability of 14,000 makes the CPC1984Y SIP relay ideal for a variety of high performance switching applications." Industrial and motor control, utility meters, meters, medical equipment and appliances. "
