TIP3055 NPN Transistor Pinout Datasheet

Introduction

The TIP3055 is a popular NPN power transistor widely used in linear amplification, audio output stages, voltage regulators, and power switching applications. It is designed to handle high current and voltage levels, making it suitable for industrial, automotive, and consumer electronics circuits. With a collector current rating of 15A and a maximum collector-emitter voltage of 60V, the TIP3055 is a robust and versatile transistor.

Encased in a TO-218 package, this transistor provides excellent thermal stability and power dissipation, allowing it to deliver up to 90W of total power dissipation when mounted on a proper heatsink. Its DC current gain (hFE) typically ranges from 20 to 70, making it suitable for both amplifier circuits and power control stages.

TIP3055 NPN Transistor

Thanks to its reliability, ruggedness, and widespread availability, the TIP3055 has become one of the most commonly used transistors in audio power amplifiers, motor drivers, SMPS, and power inverter circuits. It is also paired with its PNP complementary transistor, TIP2955, for push-pull configurations in class AB amplifier designs and other high-power applications.
