Description

PAA191 is a dual 400V, 250mA, 8 normally open

(1-Form-A) solid state relay that uses optically coupled

MOSFET technology to provide 5000Vrms of input to

output isolation.

Its optically coupled outputs, which use the patented

OptoMOS architecture, are controlled by a highly

efficient 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.
