Low-loss solid-state relays match standard pin-outs

IXYS Corporation has introduced three 60V-rated, voltage-controlled solid-state relays in 4-pin SIP packages for direct replacement of reed relays, delivering improved reliability and EMC performance.

The single-pole normally-open CPC1217Y and single-pole normally-closed CPC1219Y are rated to 200mA and 150mA respectively, and both have on-resistance of 16Ω. The CPC1218Y has lower on-resistance of 0.18Ω for systems that require ultra-low losses, and can handle currents up to 600mA.

All three devices are designed to operate with an input voltage range from 5V to 12V, and are suitable for use in security systems meeting EN50130-4. Voltage-controlled switching is achieved using an internal resistor in series with the integrated infrared LED.

Each device is manufactured using a patented OptoMOS® architecture and provides a 2500Vrms input-to-output isolation barrier.

Also, because the solid-state input generates no inductive transient voltages, the new relays eliminate the extra cost and footprint of suppression circuitry normally required with electromagnetic relays.
