Littelfuse introduces 600V, 1A power SIP relays

Littelfuse's IXYS Integrated Circuits division introduces the CPC1984Y, a 600V normally open power SIP relay rated for up to 1A DC/1Arms of sustained load current, double the load current of the company's best-selling power relay. This highly reliable device uses optically coupled MOSFET technology to provide 4000Vrms input and output isolation. In fact, the CPC1984Y SIP relay provides the best combination of load voltage and load current at 4000Vrms isolation voltage. The optically coupled output uses IXYS ICD's patented OptoMOS structure and is controlled by an efficient infrared LED.

With a typical on-resistance rating of only 0.51 ohms and a maximum rating of only 0.66 ohms, the CPC1984Y offers significantly lower on-resistance than comparable products. Its 600V blocking voltage provides sufficient design margin for 110Vrms/220Vrms power line applications for general purpose power supplies.

"By combining a 600V blocking voltage rating with a load current handling capability of 1A, the CPC1984Y SIP relay is ideal for a variety of high-performance switching applications." Said Mark Heisig, general manager and vice president of IXYS 'Integrated Circuits Division. "This includes industrial and motor controls, utility meters, meters, medical equipment and home appliances."
The CPC1984Y SIP relay offers the following key benefits:

● Lower drive power requirements to reduce CPC1984Y power consumption.
● There is no need to use a buffer circuit to suppress the arc when switching.
● The flammability rating of UL 94 V-0 ensures high flame retardancy in the plastic packaging of this device.
