The LCA182 is a 1-Form-A solid state relay which
uses optically coupled MOSFET technology to
provide 3750VRMS of input to output isolation. It
features an extremely low input control current of
only 0.25mA, the lowest available in the Clare Solid
State Relay Family. The efficient MOSFET switches
and photovoltaic die use Clare’s patented OptoMOS
architecture. The optically-coupled input is controlled
by a highly efficient GaAIAs infrared LED. The
LCA182 can be used to replace mechanical relays
and offers the superior reliability associated with
semiconductor devices. Because they have no
moving parts, they offer faster, bounce-free switching
in a more compact surface mount or though hole
package.
