The TIP120 NPN Darlington Transistor is a high-gain power transistor designed for switching and control applications in electronic circuits. Featuring a Darlington configuration and a TO-220 package, it provides high current amplification, allowing a relatively small input current to control a larger load current.
The TIP120 is suitable for controlling DC motors, relays, solenoids, lamps, and other electrical loads in electronic projects. It is commonly used with Arduino, microcontrollers, and DIY electronics systems for motor control, automation, and power switching applications.
