Bipolar (BJT) Single Transistor, Darlington, NPN, 100V, 5A, 65W, TO-220 - 

The TIP122 is a high-performance, Darlington transistor designed to handle high currents and voltages, making it an ideal choice for demanding applications such as audio amplifiers, power supplies, and switching circuits. With its high current handling capability and low saturation voltage, the TIP122 can efficiently switch high currents while minimizing power losses. Its high gain and fast switching times make it suitable for high-frequency applications, and its robust construction ensures reliable operation in harsh environments. The TIP122 is a Darlington transistor, which means it has a built-in current gain stage that provides a high current gain and low input current. This makes it ideal for applications where a high current gain is required, such as in audio amplifiers and power supplies.
