TIP122 NPN Transistor |Power Transistor for Motor Control & Switching

The TIP122 is a high-power NPN Darlington transistor designed for switching and amplifying high current loads in electronic circuits. It can handle up to 5A continuous collector current and supports up to 100V, making it ideal for motor control, LED drivers, relays, and power switching applications.

Due to its internal Darlington configuration, it provides very high current gain (hFE ~1000), allowing small base signals from microcontrollers like Arduino or Raspberry Pi to control large loads efficiently. It comes in a TO-220 package for easy mounting and heat dissipation.

This transistor is widely used in robotics, automation systems, motor speed control, inverter circuits, and general power switching applications.
