Overview
Description
MJ15004G is a high-power PNP silicon transistor, part of the classic MJ15003/MJ15004 complementary pair used in power audio amplifiers. The “G” suffix usually denotes a RoHS/green variant or a specific package from manufacturers.
Typical ratings (variant dependent): Vceo ~140 V, Ic up to about 8 A, and Ptot ~40–50 W, with maximum junction temperature around 150°C. Commonly offered in metal can styles such as TO-3.
Typical uses: output devices in Class AB audio power amplifiers or other high-voltage, high-current switching applications that require a complementary pair.
Note: exact specs and package for your MJ15004G can vary by vendor, so always consult the specific datasheet for the device you have.

Pinout
The MJ15004G is a 3‑lead NPN power transistor. Its pins are: Base (control), Collector (power input — usually tied to the metal case/heatsink), and Emitter (output/reference). Function: high‑voltage, high‑current switching/amplification in power supplies and audio/amplifier circuits. Pin order can vary by package (e.g., TO‑3P/TO‑247: pin 1 = Base, pin 2 = Collector, pin 3 = Emitter), so confirm the exact package datasheet for pin‑out and mounting details.
Manufacturer
Manufacturer: onsemi (ON Semiconductor).
What kind of company: onsemi is a global semiconductor manufacturer (an integrated device manufacturer) that designs and produces power transistors, discrete semiconductors, analog and power-management ICs and related components. The MJ15004 series was originally a Motorola product; onsemi now supplies many of those legacy power-transistor parts.
