TIP120 Transistor Explained / Description:

TIP120 is a NPN darlington pair transistor and it is also a must to have transistor in your lab. The transistor possesses some of the good features which are 5A load handling, collector-emitter voltage of 60V, emitter-base voltage of 5V. Max collector dissipation of 65 Watt and the maximum current gain of 1000 which makes this transistor ideal to use in wide variety of switching and amplification purposes in the electronic circuits.


Where We Can Use it & How to Use:

TIP120 can be used in variety of switching and amplification related applications. When using as a switch it requires only 120mA to its base to become fully saturated and drive load of 5000mA or 5A. With 5A of current one can drive verity of components like high power LEDs, LEDs strips, LED bulbs, high power relays and other switches, devise and whole part of a circuit or a completely separate device. When working as amplifier it can amplify a very little amount of audio to drive a high power speaker directly with on other extra circuitry required. It can also be used in amplifier stages and a preamplifier. Its emitter-base voltage value also makes it ideal to use with microcontroller and other devices to drive loads under 5A.

How to Safely Long Run in a Circuit:

To safely run TIP120 transistor in your applications and to get long term performance with this transistor it is recommended to not operate load of more than 60V and 5A. Check pin configurations before placing in the circuit, always use a suitable heatsink with the transistor, use a suitable base resistor with the transistor and do not store or use in temperature below -65 centigrade and above +150 centigrade.
