Working Principle

The HMA2701 optoisolator consists of an infrared LED that is optically coupled to a phototransistor. The LED is connected to the input side and transmits light when voltage is applied. The phototransistor is then connected to the output side and receives the light emitted from the LED, causing the transistor to switch on. This switching action isolates the input and output sides from each other. Additionally, the HMA2701 also features a built-in protection circuit which short-circuits the LED terminals when the input voltage exceeds the rated voltage.
