TIP125 is a type of NPN single translatable junction transistor (BJT) primarily used to control currents up to a few hundred milliamps. It is mainly used in low voltage, low power audio amplifiers, general purpose amplifying and switching circuits. The General purpose of this type of transistor is to activate or deactivate a circuit when a gate voltage or input current is applied to the base of the transistor.

The TIP125 Transistor has three pins - emitter, collector, and base. The emitter pin is the negative terminal pin of the transistor and it is connected to the ground or 0V. The base the is the controlling pin of the transistor, it is connected to the triggering voltage. The collector is the output point from where the amplified current exits the device. When a small current is passing through the base, it is then amplified and a larger current passes through the collector.

The TIP125 transistor is capable of switching and amplifying and works with the help of biasing. Biasing is when a certain voltage is applied across the base-emitter junction. In case of the TIP125, the Applied voltage needs to be about 0.7V for proper biasing. Any voltage below or above this value can’t produce the desirable current.

The TIP125 has a wide application range. Because of its switching and amplifying capability, it is extensively used in small audio amplifiers. It is also used in linear circuits driven by voltage sources like battery, rectifier or solar energy. It is also used in the general current amplifier and switching circuits. It can also be used in generators, audible alarms, audio amplifiers, and acoustics.

The TIP125 has other advantages or applications of which it can be used. It has an adequate protection against overcurrents and temperature changes. It also has low noise emission and low distortion, making it a good choice for any audio application. It also has high breakdown voltage, making it good for high voltage applications. Additionally, the building of the device is thermal and it can be used easily in any circuit without any extra protection.

The most common operating pole of the TIP125 is as a switching device. The resistance of the device is inversely proportional to the voltage applied in the base of the transistor. An increase in the applied base voltage will decrease the resistance, allowing more current to flow. This is, on the other hand, the decrease in the base voltage will increase the resistance and, in turn, decrease the current flow.

The TIP125 is quite useful because of its low cost, small size and versatile configuration, making it a workhorse for most applications. However, it has its limitation in speed, temperature, and current. The TIP125 also has a limit when working with high frequencies and large signal currents. However, it can be used for general purpose applications as it does not require any extra protection.

Overall, the TIP125 is a good choice if you are looking for an efficient and easy to use transistor. It is relatively small size makes it perfect for any small application. Its wide range of applications make it quite versatile, while its protection against overcurrents makes it a reliable choice. Therefore, the TIP125 should be considered as an ideal choice if you are looking for a simple, cost effective transistor.
