SIP relay provides up to 4000V input-to-output isolation
From the IXYS Integrated Circuits Division, of Littelfuse, the CPC1984Y is a 600V, normally open power SIP relay that has twice the load current of the company’s most popular power relay.
This relay uses optically coupled MOSFET technology to provide 4000V rms of input-to-output isolation to offer the best combination of load voltage and load current available with a 4000V rms isolation voltage. The optically coupled outputs use IXYS ICD’s patented OptoMOS architecture and are controlled by an efficient infra red LED.
Typical on-resistance is just 0.51 Ohms and maximum rating is just 0.66 Ohms, which is lower on-resistance than competitive devices, says the company. The 600V blocking voltage rating provides sufficient design margin for both 110/220V rms power line applications for universal power supplies.
Target applications are industrial and motor controls, utility meters, instrumentation, medical equipment and home appliances.
Snubbing circuits are not needed to suppress arcs when switching, notes Littelfuse.
Flammability rating is UL 94 V-0 for high flame retardance of the device’s plastic package.
The CPC1984Y SIP power relays are in volume production now.
Littelfuse is a manufacturer of technologies in circuit protection, power control and sensing. Its products are sold in over 150 countries, and are found in automotive and commercial vehicles, industrial applications, data and telecommunications, medical devices, consumer electronics and appliances.
