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 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.
