The LCB110 is a 1-Form-B relay which uses optically
coupled MOSFET technology to provide 3750V of input
to output isolation. The efficient MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS® archi-
tecture. A highly efficient GaAIAs infrared LED controls
the optically coupled input. The LCB110 has low on
resistance and is well suited for most applications
requiring a normally closed relay. The device is avail-
able in small 6-pin dual in line package in standard
though hole and surface mount lead bend.
