TIP120 Darlington Transistor

The TIP120 is a robust NPN Darlington transistor designed for general-purpose amplification and low-speed switching applications. It features a monolithic Darlington configuration with a high DC current gain (hFE) of typically 2500, allowing it to be driven by low-current microcontroller pins (like Arduino or Raspberry Pi) to control higher current loads. With a maximum collector-emitter voltage of 60V and a continuous collector current of 5A, it is perfect for driving DC motors, solenoids, relays, and high-power LEDs. The TO-220 package ensures easy mounting and effective heat dissipation. This transistor is widely used in power supply circuits, automation projects, and motor driver boards. Choose the TIP120 for its reliability, high gain, and compatibility with standard prototyping setups. It is a cost-effective solution for hobbyists and engineers looking to switch loads up to 60V and 5A safely.
