WebJul 17, 2024 · Very simply, an optocoupler integrates an infrared LED alongside a photodetector (usually a phototransistor) and acts like an optical switch. When the LED receives an input signal, the LED turns on and supplies photons to the base of the phototransistor. This then turns on the phototransistor, allowing current to flow through a … WebSimple isolating optocouplers with single-transistor output stages have typical CTR values on the range of 20% to 100%; the actual CTR value depends (among other things) on the input and output current values of …
