BC547

Small-signal NPN transistor.

Tutorial / documentation

Transistors & diodes

First tests with BC547

  1. Identify the exact BC547 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 : transistor npn petit signal.
