描述 Description

PAA140L is a 2-Form-A solid state relay which uses optically coupled MOSFET technology to provide 3750V of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare’s patented Optomos architecture. The optically-coupled input is controlled by a highly efficient GaAIAs infrared LED. The PAA140L also contains a built in load current limiting 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.
