TIP122 Transistor Explained / Description:

TIP122 is an NPN Darlington transistor, darlington transistor means there are two transistor in one package connected to increase gain at output. TIP122 transistor has a lot of good features like 5A collector current, max emitter-base voltage is 5V, max collector dissipation is 65 watt, minimum & maximum current gain is equal to 1000. This transistor is designed to use as a switch and for amplification purposes.

Where We Can Use it & How to Use:

According to its features you can use this transistor as a switch in electronic circuits to drive any load under 5A. It can be used in many applications for battery charger circuits, power supply circuits, driving motors etc. It will also perform well as an amplifier and can be used as a separate amplifier or in audio amplification stages. Moreover it can also be used as an audio preamplifier. The emitter-base voltage of this transistor is 5V DC therefore it can also be used at the output of a microcontroller and logic devices to control loads under 5A.

Applications:

• Audio Amplifier
• Audio Amplifier Stages
• Audio Preamplifiers
• Switching Loads Under 5A

How to Safely Long Run in a Circuit:

To get better performance with this darlingtion transistor we suggest to always staying below its maximum ratings. Do not operate it in circuits using more than 100V. Do not provide load more than 5A. Always use a suitable base resistor to provide required current at its base. Use a suitable heatsink to save it from overheating and do store or use it in temperature below -65 centigrade and above +150 centigrade.
