Working Principles

The ACPL-790B-300E is an optocoupler that utilizes a phototransistor to achieve electrical isolation between the input and output circuits. When an input current is applied to the LED (anode and cathode pins), it emits light that activates the phototransistor. The activated phototransistor allows current to flow from the collector to the emitter, providing an output signal that is proportional to the input signal.

Detailed Application Field Plans

The ACPL-790B-300E finds applications in various fields, including:

1. Industrial automation: Isolation and transmission of control signals in PLCs, motor drives, and power supplies.
2. Telecommunications: Signal isolation in communication equipment, such as modems and routers.
3. Medical devices: Isolation of sensitive circuits in patient monitoring systems and medical instruments.
4. Automotive electronics: Signal transmission and noise suppression in automotive control modules.
