TIP2955 PNP Power Transistor Pinout Datasheet

Introduction

The TIP2955 is a PNP silicon power transistor designed for high-current and medium-voltage applications. Packaged in the TO-247 case, this device offers superior thermal conductivity, mechanical strength, and power handling capabilities compared to older TO-218 or TO-3P packages. It is commonly used in linear power amplifiers, regulated power supplies, UPS systems, and motor drivers, where reliability and efficiency are critical.

With a collector-emitter voltage (Vce) rating of 60V and a collector current of up to 15A, the TIP2955 is well-suited for driving large loads. Its power dissipation rating of 90W allows it to handle significant energy while maintaining safe operation when used with a proper heatsink. The transistor exhibits a DC gain (hFE) range between 20 and 70, which makes it ideal for both switching and linear amplifier applications.

TIP2955 PNP Power Transistor

The TIP2955 is often paired with its complementary NPN counterpart, the TIP3055, to form a robust push-pull amplifier stage. This combination is widely used in Class AB audio amplifiers, ensuring low distortion, efficient current drive, and stable operation. Its versatility and availability make the TIP2955 a staple in both consumer electronics and industrial electronics projects.
