has two independently controlled optically coupled
MOSFET switches. The MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS
®
architecture to provide 3750 V
rms
of input to output
isolation. The optically coupled output is controlled
by a highly efficient GaAIAs infrared LED. This dual
pole OptoMOS relay provides a more compact design
solution than discrete single-pole relays in a variety of
applications and saves board space by incorporating
both switches in a single 8-Pin 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
performance and/or a reduced lifetime expectancy.
Recommended soldering processes are limited to
260ºC component body temperature for 10 seconds.
