TIP122

NPN Darlington transistor.

Tutorial / documentation

Transistors & diodes

First tests with TIP122

  1. Identify the exact TIP122 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 darlington npn.
