LAA125L Dual Single Pole OptoMOS Relays INTEGRATED CIRCUITS DIVISION Description Parameter Ratings Units Blocking Voltage 350 V LAA125L is a dual normally open (1-Form-A) Solid P Load Current 150 mA / mA State Relay that has two independently controlled, rms DC On-Resistance (max) 18 optically coupled MOSFET switches with an additional current limiting circuit. The optically coupled combination of MOSFET switches and photovoltaic die Features provide 3750V of input/output isolation. rms Current Limiting 3750V Input/Output Isolation The optically coupled outputs, which use patented rms Low Drive Power Requirements OptoMOS architecture, are controlled by a highly (TTL/CMOS Compatible) efficient GaAIAs infrared LED. No Moving Parts High Reliability This dual switch OptoMOS relay provides a more Arc-Free With No Snubbing Circuits compact design solution than discrete single-pole No EMI/RFI Generation relays in a variety of applications, and saves board Small 8 Pin Packages space by incorporating both switches in a single 8-Pin Machine Insertable, Wave Solderable package.
