Working Principles

The HCPL-7520-300E optocoupler utilizes an LED and a phototransistor to achieve electrical isolation. When a current is applied to the LED, it emits light that is received by the phototransistor. This light triggers the phototransistor to conduct, allowing current to flow through the output circuit. The input and output circuits are electrically isolated, providing protection against voltage spikes and noise.
