Description
LCA125L is a current-limiting, 300V, 170mA, 20,
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.
The LCA125L 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
compact surface mount or thru-hole package.
