TIP122 Darlington NPN Transistor (Pack of 4)

The TIP122 is indeed a Darlington pair transistor, specifically an NPN-type transistor. Darlington pairs are configurations of two bipolar transistors, where the first transistor drives the base of the second transistor, effectively amplifying the current gain of the overall configuration.

Here are the key specifications of the TIP122:

1. Collector Current (I_C): 5A (this is the maximum continuous current the transistor can handle without damage).
2. Collector-Emitter Voltage (V_CE): Typically around 100V.
3. Gain (h_FE): Very high, typically around 1000. This indicates that a small change in the base current can result in a much larger change in the collector current, making it suitable for applications requiring high current amplification.
4. Package Type: It’s commonly available in TO-220 package, which provides good thermal conductivity for heat dissipation.
5. Application: The TIP122 is commonly used in applications requiring high current amplification, such as power switching circuits, motor control, and various other high-current applications.

With its high collector current rating and high gain value, the TIP122 is a versatile transistor for applications where high current amplification is needed.
