Description
LAA710 is a Dual 1 Form-A solid state relay that has
two independently controlled optically coupled
MOSFETs. The efficient MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS
®
architecture to provide 3750 V
RMS
of input to output
isolation. The optically coupled inputs are controlled
by highly efficient GaAIAs infrared LEDs. Dual pole
OptoMOS relays provide a more compact design
solution than discrete single pole relays in a variety of
applications. The dual pole relays save board space
by incorporating both relays in a single 8-pin package.
