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 GaAIAs infrared LED.

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.
