Working Principles

The ACPL-785J-060E is an optocoupler that utilizes a phototransistor to provide electrical isolation between the input and output circuits. When an input current is applied to the anode and cathode pins, the phototransistor is activated, allowing current to flow from the collector to the emitter. This enables signal transmission without direct electrical connection, providing isolation and protection.
