PAA140L is a current-limited, dual, normally open
(1-Form-A) solid state relay that uses optically coupled
MOSFET technology to provide 3750Vrms of input to
output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
Featuring low on-resistance and very high load current
handling capability, it is suitable for a variety of high
performance switching applications.
