LAA127L 250V, 170mA Dual Single-Pole Current Limiting, Normally Open Relays INTEGRATED CIRCUITS DIVISION Parameter Ratings Units Description Blocking Voltage, AC/DC 250 V LAA127L is a dual single-pole, normally open P (1-Form-A) current-limiting Solid State Relay. The Load Current 170 mA / mA rms DC combination of super efficient MOSFET switches and On-Resistance (max) 10 photovoltaic die provides 3750V of input to output rms isolation. Features The optically coupled outputs, which use the Current Limiting Device patented OptoMOS architecture, are controlled by a 3750V Input/Output Isolation rms highly efficient infrared LED. Low Drive Power Requirements Higher Reliability than Electromechanical Relays Dual single-pole OptoMOS relays provide a more No EMI/RFI Generation compact design solution than two discrete single-pole Small 8-Pin Package relays in a variety of applications, and save board Flammability Rating UL 94 V-0 space by incorporating both switches in a single 8-pin Surface Mount Tape & Reel Versions Available package.
