Units
LAA110L is a dual normally open (1-Form-A) Solid
State Relay that has two independently controlled,
optically coupled MOSFET switches with an additional
current limiting circuit. The MOSFET switches and
photovoltaic die use optically coupled MOSFET
technology to provide 3750Vrms of input/output
isolation.

Features
• 3750Vrms Input/Output Isolation
• Current Limiting Device
• Low Drive Power Requirements (TTL/CMOS
Compatible)
• No Moving Parts
The optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
• High Reliability
• Arc-Free With No Snubbing Circuits
• No EMI/RFI Generation
• Machine Insertable, Wave Solderable
• Surface Mount and Tape & Reel Versions Available
• Small 8-Pin Package
This dual switch 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.
