TIP120 is a polarisation N-Channel enhancement power transistor. This power transistor can handle current up to 5A and can operate with a collector-emitter voltage of up to 60V. It can be used in the power amplification of a variety of circuits such as linear, switching, and low-level signal amplification circuits like those used to control motors and other high-powered devices. In addition, the TIP120 can be used for audio amplifiers and other applications requiring high current handling.

In terms of its application field, the TIP120 can be used as an interface between low-level analog signals and higher current levels. One such application is in the control of a high current device such as a relay. The TIP120 can be used to amplify low-level signals to the levels necessary to trigger the relay. This is just one example of the many applications that the TIP120 can be used for.

Now let’s turn to the TIP120’s working principle. The TIP120 is essentially an N-Channel enhancement power transistor. This means that when the base-emitter junction of the TIP120 is forward biased, electrons are injected into the base, which in turn causes current to flow through the collector-emitter junction. The collector-emitter voltage will then drop, allowing current to flow through the load. This is how the TIP120 works as an amplifier, taking a low-level input signal and amplifying it to the desired level.

As a single bipolar transistor, the TIP120 has three pins, the base, the collector, and the emitter. In order to use the TIP120, you must first connect a biasing resistor across the base-emitter terminals. The voltage that is applied to the base then determines the amount of current that will flow through the collector-emitter terminals. The bias voltage must be greater than the base-emitter forward voltage to turn on the transistor. If the bias voltage is lower than the forward voltage, then the transistor is turned off.

The TIP120 is a versatile and powerful transistor. It can handle currents up to 5A, and can be used in many different applications ranging from low-level signal amplification to high current devices such as relays. The fact that it has three pins makes it easy to use, and the transistor can be used in a variety of circuits. The TIP120 is a great choice for anyone looking for a reliable, high-powered transistor.
