Description
The LCA110L is a 1-Form-A solid state relay which
uses optically coupled MOSFET technology to pro-
vide 3750V of input to output isolation. The efficient
MOSFET switches and photovoltaic die use Clare’s
patented OptoMOS architecture. The optically-cou-
pled input is controlled by a highly efficent GaAIAs
infrared LED. The LCA110L can be used to replace
mechanical relays and offers the superior reliability
associated with semiconductor devices. Because
they have no moving parts, they can offer faster,
bounce-free switching in a more compact surface
mount or through hole package.
