Working Principles

The EL8172FSZ optocoupler consists of an infrared LED and a phototransistor. When a current is applied to the LED, it emits infrared light. This light is then detected by the phototransistor, causing it to conduct current. The optocoupler provides electrical isolation between the input and output circuits while transferring the signal from the input side to the output side.
