PAA191 is a dual 400V, 250mA, 8 normally open
(1-Form-A) solid state relay that uses optically coupled
MOSFET technology to provide 5000V
rms
of input to
output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
This dual single-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.
