Dual Single-Pole OptoMOS® Relay

Manufacturer's part number :


Manufacturer UK_IXY_SI


Description :

LAA125L is a dual normally open (1-Form-A) Solid State Relay that has two independently controlled, optically coupled MOSFET switches with an additional current limiting circuit. The optically coupled combination of MOSFET switches and photovoltaic die provide 3750Vrms of input/output isolation.

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

This dual switch 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.
