From Makers Electronics's description

The TIP120 is an NPN Darlington Power Transistor. It can switch loads up to 60V with a peak current of 8A and a continuous current of 5A. This makes it suitable for medium and high-power electronics like controlling motors, solenoids or high-power LEDs. Pin Configuration Pin Number Pin Name Description 1 Base Controls the biasing of the transistor, Used to turn ON or OFF the transistor 2 Collector Current flows in through the collector, normally connected to the load 3 Emitter Current Drains out through emitter, normally connected to ground Features NPN Medium-power Darlington Transistor High DC Current Gain (hFE), typically 1000 Continuous Collector current (IC) is 5A Collector-Emitter voltage (VCE) is 60V Collector-Base voltage (VCB) is 60V Emitter Base Voltage (VBE) is 5V Base Current(IB) is 120mA The peak load current is 8A Available in To-220 Package Note: Complete Technical Details can be found on the TIP120 datasheet given at the end of this page. TIP120 Transistor Overview The TIP122 is a Darlington pair NPN transistor. It functions like a normal NPN transistor, but since it has a Darlington pair inside it has a good collector current rating of about 5A and a gain of about 1000. It can also withstand about 60V across its collector-emitter and hence can be used to drive heavy loads. If you need more voltage then you can check other transistors in the same family lit the TIP122. The Darlington pair inside this transistor is shown clearly as its internal circuit schematic below As you can see, there are two transistors inside this TO-220 package in which the emitter of the first transistor is connected with the base of the second transistor and the collector of both transistors is connected together to form a Darlington pair. This increases the current gain and current rating of this transistor. Where to use TIP120 Transistor TIP120 transistor is known for its high current gain (hfe = 1000) and high collector current (IC =5A) hence it is normally used to control loads with high current or in applications where high amplification is required. This transistor has a low Base-Emitter Voltage of only 5V hence can be easily controlled by a Logic device like microcontrollers. However, care has to be taken to check if the logic device can source up to 120mA. So, if you looking for a transistor that could be easily controlled by a Logic device to switch high power loads or to amplify high current then this Transistor might be an ideal choice for your application. Applications Can be used to switch high-current (up to 5A) loads Can be used as medium Power switches Used where high amplification is needed Speed control of Motors Inverter and other rectifier circuits Component Datasheet TIP120 Datasheet
