PC817

Optocoupler for signal isolation.

Tutorial / documentation

Transistors & diodes

First tests with PC817

  1. Identify the exact PC817 variant, package and manufacturer documentation.
  2. Identify power, ground and signal pins in the documentation. Assemble the circuit with power disconnected.
  3. Follow the manufacturer’s evaluation circuit. Use a current-limited low-voltage supply and the recommended logic levels.
  4. Mesurez les signaux d’entrée et de sortie. Comparez leur comportement à la fonction : optocoupleur pour isolation de signal.
