TIP122 NPN Darlington Bipolar Junction Transistor – 5A 100V TO-220

The TIP122 is a high-current NPN Darlington bipolar junction transistor designed for power switching and amplification applications. It combines two NPN transistors in a Darlington configuration to deliver extremely high current gain (hFE ≥ 1000) with minimal base current requirement. With a collector current capability of up to 5A and collector-emitter voltage up to 100V, the TIP122 is ideal for driving motors, relays, solenoids, LEDs, and other power loads directly from microcontrollers or logic circuits. Its TO-220 package provides effective heat dissipation, making it suitable for medium- to high-power control applications.
