Introduction

LBB120 is a dual 250V, 170mA, 20Ω 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 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.
