Dual Single-Pole, Normally Closed OptoMOS® Relay

Manufacturer's part number :


Manufacturer UK_IXY_SI


Description :

LBB120 is a dual 250V, 170mA, 20ohms normally closed (1-Form-B) relay that features low on-resistance combined with enhanced peak load current handling capability. Provided in an 8-pin SOIC package, and employing optically coupled MOSFET technology, it provides 3750Vrms of input/output isolation.

Its 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 discrete single-pole relays in a variety of applications by incorporating both relays in a single 8-pin package.
