MJE15032 NPN Power Transistor Datasheet

Introduction

The MJE15032 is a high-voltage, high-speed NPN power transistor designed primarily for audio amplifier drivers, power regulators, and high-fidelity circuits. Manufactured with modern epitaxial-base technology, it offers excellent performance in terms of switching speed, gain stability, and thermal reliability. The device is commonly used in professional-grade audio amplifier stages where linearity, power handling, and low distortion are critical.

This transistor comes in a TO-220 package, making it well-suited for applications where efficient heat dissipation and compact design are required. With a collector-emitter voltage rating of 250V, a collector current of 8A, and a power dissipation capability of 50W, the MJE15032 is a strong choice for circuits that demand both high voltage and high current performance.
