How We Can Use it & How to Use:

TIP120 Transistor can be used in a variety of switching and amplification-related applications. When used as a switch it requires only 120mA to its base to become completely saturated and drive a load of 5A. With 5A of current one can drive a verity of components such as high-power LED bulbs, LEDs, high-power relays, LEDs strips, and other switches, devise and full part of a circuit, or a fully separate device. When we work as amplifiers amplify a very small quantity of audio to drive a high-power speaker directly with on other extra circuits required. It can also be used in the preamplifier and amplifier stages. Its emitter_to_base voltage cost also makes it ideal to use with microcontrollers and other devices to drive loads below 5A.

 Applications of TIP 120 Darlington Transistor

  • It is used in Microcontrollers
  • Audio Preamplifiers and Its Stages
  • Switching or Driving Loads under 5A
  • Audio Power Amplifier appliances
  • Audio Amplifier Stages circuits

Where we to Safely Long Run in a Circuit

To get long-term performance with this transistor it is recommended to not operate a load of more than 60V and 5A.

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