Dual Single-Pole, Combination OptoMOS® Relay

Manufacturer's part number :


Manufacturer UK_IXY_SI


Description :

LBA127L comprises two independent solid state relays (one current-limited, single-pole, normally open (1-Form-A) relay and one single-pole, normally closed (1-Form-B) relay), in an 8-pin package that employs optically coupled MOSFET technology to provide 3750Vrms of input to output isolation.

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

LBA127L is designed to provide an ideal solution where a complementary Form-A/Form-B relay pair is required in a space-saving single package.
