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.
