XBB170 is a dual 350V, 100mA, 50
Ω, normally
closed (1-Form-B) relay that features low
on-resistance. The efficient MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS
architecture to provide 3750V
rms of input to output
isolation. The optically coupled outputs are controlled
by highly efficient GaAIAs infrared LEDs.
Dual single-pole OptoMOS relays provide a more
compact design solution than discrete single-pole
relays in a variety of applications. The dual relay
configuration saves board space by incorporating
both relays in a single 8-pin package.
