Description
The LCA120 is a single-pole, normally open
(1-Form-A) solid state relay that uses optically coupled
MOSFET technology to provide 3750V_rms of input to
output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
LCA120 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.
