TIP122 Darlington Pair NPN Transistor 100V-5A

The TIP122 Transistor is a Darlington pair NPN transistor. TIP122 is a medium-power transistor that can handle up to 5A of collector current and 100V of collector-emitter voltage. It has a high current gain of 1000, which means that a small current applied to the base can control a much larger current flowing through the collector. This makes it ideal for switching high-current loads, such as motors, relays, and solenoids.

The TIP122 Transistor also has a low base-emitter voltage of only 5V, which means that TIP122 can easily drive by logic circuits, such as microcontrollers. This makes it a versatile transistor that can use in a wide variety of applications.

It is important to note that the TIP122 can only handle a maximum collector current of 5A. If you are trying to switch a load that draws more than 5A, you will need to use a different transistor.

The TIP122 NPN transistor works on the principle of a Darlington pair. A Darlington pair is a configuration of two transistors connected in series, with the collector of the first transistor connected to the base of the second transistor. This configuration results in a transistor with a very high current gain.

The TIP122 NPN transistor has a current gain of 1000 (typ). This means that for every 1 milliamp of current applied to the base, the transistor will conduct 1 ampere of current through the collector. This high current gain makes the TIP122 ideal for switching high-current loads.

The NPN transistor TIP122 has a base-emitter voltage (VBE) of 5V (typ). This means that a minimum of 5V must be applied to the base of the transistor in order to turn it on. The collector-emitter voltage (VCE) of the TIP122 can range from 0V to 100V (max).

TIP122 Transistor is a good choice for projects that require high current switching or amplification. It is important to note that the TIP122 NPN transistor is a polarized transistor. This means that the base, collector, and emitter pins must connect in the correct order. The TIP122 NPN transistor has three pins, which are labeled as follows:

• Base (B): The base pin is use to control the transistor. A small current applied to the base pin will turn on the transistor, allowing a large current to flow through the collector and emitter.
• Collector (C): The collector pin is the output pin of the transistor. The current that flows through the collector pin is controlled by the current that is applied to the base pin.
• Emitter (E): The emitter pin is the input pin of the transistor. The current that flows through the emitter pin is the same as the current that flows through the collector pin.
