Overview

Description

The 2N5551 is a high-power NPN bipolar junction transistor (BJT) commonly used in various electronic applications, particularly in switching and amplification circuits. It has a maximum collector current of 15A and a maximum collector-emitter voltage of 160V, making it suitable for high-voltage and high-current applications.
Key specifications include a DC current gain (h_FE) range of 20 to 300 and a transition frequency (f_T) around 100 MHz, allowing for versatile use in both audio and RF applications. The transistor is housed in a TO-220 package, which facilitates effective heat dissipation.
The 2N5551 is often paired with its complementary PNP counterpart, the 2N5401, for push-pull amplifier configurations. Its robust performance and reliability make it a popular choice in power amplifiers, power regulators, and motor control circuits. When designing circuits with the 2N5551, proper biasing and thermal management are essential to optimize performance and prevent overheating.

Pinout

The 2N5551 is a NPN bipolar junction transistor (BJT) commonly used for amplification and switching applications. It typically comes in a TO-220 package.
Pin Count and Functions:
- Pin 1 (Base): This is the control terminal that regulates the current flow between the collector and emitter. A small current at the base allows a larger current to flow from the collector to the emitter.
- Pin 2 (Collector): This terminal collects the charge carriers (electrons for NPN) and is connected to the load.
- Pin 3 (Emitter): This terminal emits charge carriers into the external circuit and is usually connected to ground in most applications.
In summary, the 2N5551 has three pins: Base, Collector, and Emitter, each serving essential roles in transistor operation.
