Working Principle of the SFH636-X009

At the heart of the SFH636-X009 is a light-emitting diode (LED) which is connected to an LED terminal on one side of the optoisolator. On the other side is a phototransistor, which is activated by light received through the LED. This connection of the LED and phototransistor allows for electrical isolation of the two circuits. Through this electrical isolation, a signal from the input side of the optoisolator can be transmitted across the separation gap, having been converted into a light signal and then back to an electrical signal on the output side. The SFH636-X009 has a high isolation voltage rating.
