PAA140L is a dual normally open (1-Form-A) solid
state relay that uses optically coupled MOSFET
technology to provide 3750Vrms of input to output
isolation. The efficient MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS
architecture. The optically-coupled outputs are
controlled by highly efficient GaAIAs infrared LEDs.
The PAA140L also contains a built-in load current
limiting feature. This, combined with low on-resistance
and very high load current handling capability, makes
it suitable for a variety of high performance switching
applications.
