LBB120 is a dual 250V, 170mA, 20

 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 3750V

rms 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.
