Description
LCA120L is a current-limiting, 250V, 150mA, 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.
Use the LCA120L to replace mechanical relays
because it offers the superior reliability associated with
semiconductor devices. Since it has no moving parts,
it can offer faster, bounce-free switching in a more
compact surface mount or thru-hole package.
