TIP122 Transistor Pinout, Equivalent, Uses, Features
TIP122 Transistor is an NPN Darlington transistor. The Darlington transistor means there are two transistors in one pack joined to increase gain at the output. TIP122 Darlington transistor has a lot of good features, like 5A collector current, maximum emitter-base voltage is 5V, maximum collector dissipation is 65 watt, and so on. This transistor is manufactured to use as a switch and for amplification purposes. TIP122 Transistor Pinout configuration is given below.

How We Can Use it & How to Use:
This transistor you can use as a switch in electronic circuits to drive any load under 5A according to its features. This transistor can be used in many applications for power supply circuits, battery charger circuits, driving motors, etc. It will also perform well as an amplifier and can be used as a different amplifier or in audio amplification steps. Furthermore, this transistor can also be used as an audio preamplifier and The emitter-base voltage of this transistor is 5V DC. So this transistor can also be used at the output of a microcontroller and logic devices to control loads below 5A.
Applications of TIP122 transistor:
Safe Long Run in a Circuit:
To get very good performance with this Darlington transistor we suggest always stopping below its max ratings. It can not be work in circuits using more than100V. Do not put load over and always use a suitable base resistor to supply the required current on its base. Use a suitable heatsink to save it from overheating and to store its temperature below -65 centigrade and more than +150 centigrade.
