MJE2955T PNP Power Transistor Datasheet

Introduction

The MJE2955T is a PNP silicon power transistor designed for use in power amplifiers, voltage regulators, and general-purpose power switching applications. Packaged in the TO-220 plastic case, it is the modern equivalent of the classic MJ2955 transistor, which comes in a TO-3 metal case. The MJE2955T provides a more compact, cost-efficient, and PCB-friendly version while maintaining excellent electrical and thermal performance.

This transistor is widely used in audio amplifier output stages, DC motor control circuits, and inverter or power supply systems. It features a collector current (Ic) up to 10A, a collector-emitter voltage (Vce) up to 60V, and a power dissipation capacity up to 75W, which allows it to handle substantial loads efficiently. Its Darlington compatibility with the MJE3055T (NPN) makes it a perfect complementary pair for push-pull and class AB amplifier configurations.

MJE2955T PNP Power Transistor

Because of its high reliability, linear response, and affordability, the MJE2955T remains one of the most popular PNP transistors among circuit designers, technicians, and hobbyists. It can handle heavy-duty switching operations with proper heat sinking, making it ideal for both industrial and educational electronics projects where medium-to-high current amplification is required.
