Dual Single-Pole, Normally Open OptoMOS® Relay

Manufacturer's part number :


Manufacturer UK_IXY_SI


Description :

PAA191 is a dual 400V, 250mA, 8ohms normally open (1-Form-A) solid state relay that uses optically coupled MOSFET technology to provide 5000Vrms of input to output isolation.

Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient GaAIAs infrared LED.

This dual single-pole OptoMOS relay provides a more compact design solution than discrete single-pole relays in a variety of applications, and saves board space by incorporating both switches in a single 8-pin package.
