Description
LCA712 is a normally open (1-Form-A) solid state
relay that uses optically coupled MOSFET technology
to provide 3750Vrms of input to output isolation, and
that features very low off-state leakage current.

Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
Features
• Very Low Off-State Leakage Current: 10nA
• Low On-Resistance: 0.5
• High Current Handling Capability: 1A
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
• Greater Reliability than Electromechanical Relays
• No EMI/RFI Generation
The LCA712 can be used to replace mechanical
relays, and offers the superior reliability associated
with semiconductor devices. Because it has no moving
parts, it offers faster, bounce-free switching in a more
compact surface mount or thru-hole package.
