DESCRIPTION
The PS7241E-1B is an optically coupled element that combines a GaAs infrared LED on the input side with a
normally close MOS FET on the output side to realize an excellent cost performance.
The small, thin package and high sensitivity of this element makes it ideal for battery-driven mobile devices, and its
small offset voltage at power-on and good linearity also make it suitable for controlling micro analog signals.
