TIP120 NPN Darlington Transistor – 5A 60V

The TIP120 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, providing extremely high current gain (hFE ? 1000) while requiring minimal base current for operation. With a collector current capability of up to 5A and collector-emitter voltage up to 60V, the TIP120 is ideal for driving motors, relays, solenoids, LEDs, and other medium-to-high power loads directly from microcontrollers or logic circuits. Its TO-220 package allows efficient heat dissipation for power applications.
