LAA710 is a dual normally open (1-Form-A) Solid
State Relay that comprises two independently
controlled, optically coupled MOSFET switches. The
combination of super efficient MOSFET switches and
photovoltaic die provides 3750Vrms of input to output
isolation.

Features
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
• Greater Reliability than Electromechanical Relays
• No EMI/RFI Generation
The optically coupled outputs, which use the
patented OptoMOS architecture, are controlled by a
highly efficient infrared LED.
• Small 8-Pin Package
• Flammability Rating UL 94 V-0
• Surface Mount Tape & Reel Version Available
Dual OptoMOS relay provides a more compact design
solution than discrete single-pole relays in a variety of
applications, and saves board space by incorporating
both switches in a single 8-pin package.
