Solid State Relay features 80 mA load current rating.

Press Release Summary:

Featuring single-pole, normally closed design, 800 V Model PLB171P is designed to provide 7 mm of separation between 2 output pins and uses optically coupled MOSFET technology to provide input-to-output isolation of 5,000 Vrms. Optically coupled outputs are controlled by infrared LED. Designed to replace electromechanical relays, PLB171P provides bounce-free switching in compact surface-mount package. It is suited for industrial controls, meters, AC line voltage equipment, and multiplexers.

IXYS Integrated Circuits Division Introduces New 800V Solid State Relay

The PLB171P offers increased output pin clearance and superior reliability over electromechanical relays

Beverly, Massachusetts, USA – IXYS Integrated Circuits Division (ICD), Inc., a wholly owned subsidiary of IXYS Corporation (NASDAQ: IXYS), announced the immediate availability of the PLB171P, 800V, single-pole, normally closed (1-Form-B) Solid State Relay (SSR) with an 80mA load current rating. The PLB171P is specially designed to provide 7mm of separation between the two output pins and uses optically coupled MOSFET technology to provide an enhanced input-to-output isolation of 5000Vrms. Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient infrared LED.

The PLB171 is designed to replace, and offers superior reliability over, electromechanical relays. This device provides bounce-free switching in a compact surface-mount package. The device features a low input LED current to activate the bidirectional relay outputs, comprised of two MOSFETs in an ‘AC switch’ configuration.

The 800 volt load voltage rating and the output pin clearance distance makes this device suitable for industrial controls, meters (watt-hour, water, gas), AC line voltage equipment, medical equipment (patient/equipment isolation), high voltage instrumentation, multiplexers, data acquisition, electronic switching, I/O subsystems and motor control.

Coupled with the Zilog MCU’s, as controllers and drivers, it enables digital power control, to reduce power consumption, activate actuators, valves, sensors and other devices. With its AC capabilities, the PLB171P is ideal for reducing standby power consumption, by cutting the power to devices that are not in use, thus reducing ‘Vampire Power’.

Approvals include: UL Certified Component: File E76270, EN/IEC 60950 Certified Component, and TUV Certificate B 13 12 82667 003

Pricing and Availability

The PLB171P SSR is available in production quantities. Pricing for OEM quantities of 25KU is $2.07. For additional information, please contact your local sales representative: or visit$file/PLB171.pdf for the datasheet.
