Disadvantages: - Limited maximum collector-emitter voltage (80 V). - Relatively low collector current (50 mA).

Working Principles

The ACPL-782T-300E optocoupler operates based on the principle of optical coupling. When a current is applied to the internal LED, it emits light. This light is then detected by the internal phototransistor, which generates an output current proportional to the intensity of the received light. The electrical isolation between the input and output circuits ensures that there is no direct electrical connection between them.
