Description
P
The LCA110 is a 1-Form-A Solid State Relay which
uses optically coupled MOSFET technology to
provide 3750V
of input to output isolation. The
rms
efficient MOSFET switches and photovoltaic die
use Clare’s patented OptoMOS® architecture. The
optically coupled output is controlled by a highly
efficient GaAIAs infrared LED. The LCA110 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 though hole package.
Approvals
• UL Recognized: File Number E76270
• CSA Certified: File Number LR 43639-10
• EN/IEC 60950-1:2001 Compliant

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
