The LCA710 is a 60V, 1A, 0.5, normally open
(1-Form-A) solid state relay featuring low
on-resistance and high current handling capability. It
uses optically coupled MOSFET technology to provide
3750Vrms of input to output isolation.

Features
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
• Low On-Resistance: 0.5
• High Current Handling Capability: 1A
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements (TTL/CMOS
Compatible)
• No Moving Parts
• High Reliability
• Arc-Free With No Snubbing Circuits
• No EMI/RFI Generation
The LCA710 can be used to replace mechanical
relays, and offers the superior reliability associated
with semiconductor devices. Because it has no moving
parts, it can offer faster, bounce-free switching in a
more compact surface mount or thru-hole package.
• Small 6-Pin Packages
• Machine Insertable, Wave Solderable
• Surface Mount and Tape & Reel Versions Available
