LCA712 is a normally open (1-Form-A) solid state
relay that uses optically coupled MOSFET technology
to provide 3750V
rms
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.

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
