LAA120L 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 employ optically coupled MOSFET
technology to provide 3750Vrms of input/output
isolation.

Features
• Two Current Limited Relays in One Package
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements (TTL/CMOS
Compatible)
• No Moving Parts
• High Reliability
The optically coupled outputs, that use patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
• Arc-Free With No Snubbing Circuits
• FCC Compatible
• VDE Compatible
• No EMI/RFI Generation
• 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.
