PLA140L is a 1-Form-A solid state relay which uses
optically coupled MOSFET technology to provide
3750V of input to output isolation. The efficient MOS-
FET switches and photovoltaic die use Clare’s patent-
ed Optomos architecture. The optically-coupled input
is controlled by a highly efficient GaAIAs infrared LED.
The PLA140L also contains a built in load current lim-
iting feature. This combined with a low on resistance
and very high load current handling capabilities makes
it suitable for a variety of high performance switching
applications.
