About TIP122:
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 100V across its collector- Emitter hence can be used to drive heavy loads.

This 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 the only 5V hence can be easily controlled by a Logic device like microcontrollers. Although care has to be taken to check if the logic device can source up to 120mA.
