概述

Description

MJ15004G is a high‑power NPN bipolar junction transistor (BJT) from the MJ15004/05 family (Motorola/Onsemi). It’s commonly used as a power output or pass device in audio amplifiers, switching supplies, and motor drivers. The “G” suffix typically denotes a RoHS/green packaging variant, depending on the vendor.
Key points:
- Type: NPN power transistor
- Typical ratings: Vceo around 120 V; Ic in the ~8–15 A range; Ptot in the tens of watts with adequate heatsinking
- Gain: hFE broadly tens to low hundreds depending on current and temperature
- Package: Often TO-3 or TO-220 style; requires proper heatsinking and consideration of safe operating area (SOA)
- Complement: MJ15005G (PNP)
For exact values, check the specific datasheet for your date code and package variant.

Features

MJ15004G is a high‑voltage NPN silicon power transistor. Key features:
- Type: NPN silicon power transistor
- Voltage/current: Vceo ≈ 200 V; Ic typically up to 8–10 A
- Power: Pd ≈ 110–125 W with proper heatsinking
- Gain: Moderate gain (hFE varies with Ic and temperature)
- Packaging: TO‑3 style metal can (Pb‑free “G” version)
- Complementary pair: Works with MJ15003 (PNP) for push‑pull
- Applications: Audio power amplifiers, high‑voltage switching applications
- Compliance: Pb‑free/RoHS‑compliant (G suffix)
Note: Exact values can vary by manufacturer and datasheet revision; always verify the specific part’s data sheet for precise ratings.

Pinout

MJ15004G is a 3‑lead high‑voltage NPN power transistor. Pin functions (typical pinout):
- Pin 1: Base
- Pin 2: Collector (also connected to the metal mounting tab)
- Pin 3: Emitter
Note: Always verify the exact pin numbering from the manufacturer's datasheet for the specific package variant.

Manufacturer

Manufacturer: ON Semiconductor (originally a Motorola part).
What kind of company: ON Semiconductor is an American semiconductor manufacturer that designs and produces discrete power transistors, analog and power-management ICs and other semiconductor components.

Application

MJ15004G is a high‑voltage, high‑current power transistor (complement to MJ15003). Common applications:
- High‑power audio amplifier output stages (push‑pull)
- Linear and switching power supplies/regulators
- Industrial drives and motor‑control circuits needing high voltage/current
