The LCA182 is a 1-Form-A solid state relay that
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 output is
controlled by a highly efficient GaAlAs 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 through-hole
package.

Manufacturing Information
Soldering
For proper assembly, the component must be
processed in accordance with the current revision
of IPC/JEDEC standard J-STD-020. Failure to
follow the recommended guidelines may cause
permanent damage to the device resulting in impaired
