Another advantage of the tip120 transistor is its easy availability and affordability. It is widely available in the market and can be purchased at a reasonable price, making it a popular choice among hobbyists and electronics enthusiasts.
The tip 120 transistor also has a Darlington pair configuration, which provides a very high current gain. This makes it an excellent choice for applications that require high current amplification, such as in motor control circuits.
Overall, the tip120 transistor is a versatile and widely used component in the field of electronics. Its high current handling capability, affordability, and availability make it an ideal choice for a wide range of applications. With its ability to switch and amplify high currents and voltages, the tip120 transistor is an essential component in many electronic projects.
TIP120 Transistor Pins Configuration
The TIP120 transistor has three pins, which are labeled as the emitter (E), base (B), and collector (C). The pinout configuration of the TIP120 transistor is as follows:
The emitter pin (E) is typically the pin on the left-hand side of the transistor when viewed from the front with the flat face of the transistor facing towards you. The emitter is connected to the negative terminal of the circuit or power supply.
The base pin (B) is located in the center of the transistor and is connected to the control or input signal of the circuit. It is important to note that the TIP120 transistor requires a minimum base current of 100mA to fully turn on, so it is often used with a driver circuit to provide the necessary current.
The collector pin (C) is typically located on the right-hand side of the transistor and is connected to the load or output of the circuit. The collector is connected to the positive terminal of the power supply.
It is important to note that the TIP120 transistor is a Darlington transistor, which means that it contains two NPN transistors connected in a way that provides a very high current gain. As a result, the collector current of the TIP120 transistor is the sum of the collector currents of the two internal transistors.
