Dual Single-Pole, Normally Open OptoMOS® Relay

Manufacturer's part number :


Manufacturer UK_IXY_SI


Description :

LAA127L is a dual single-pole, normally open (1-Form-A) current-limited Solid State Relay. The combination of super efficient MOSFET switches and photovoltaic die provides 3750Vrms of input to output isolation.

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

Dual single-pole OptoMOS relays provide a more compact design solution than two discrete single-pole relays in a variety of applications, and save board space by incorporating both switches in a single 8-pin package.
