Product details

Overview

MJ15016G from onsemi is a complementary PNP silicon power transistor designed for high-power linear and switching applications including audio amplifiers, stepping motor drivers, and inductive load control. It delivers 15 A continuous collector current, supports 120 V_CEO, dissipates up to 180 W at T_C = 25 °C, and features a safe operating area optimized for rugged linear operation in Class AB amplifier output stages.

For engineers reviewing the MJ15016G datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, TO-204 (TO-3) metal package, second-breakdown robustness, f_T of 6.0 MHz at I_C = 1.0 A, and compatibility with complementary NPN MJ15015G in push-pull configurations.

Technical Context

The MJ15016G operates as a high-current, high-voltage PNP bipolar junction transistor with base-emitter forward biasing enabling linear amplification or saturated switching. Its safe operating area (SOA) is defined by thermal limits, bonding wire current capacity, and second-breakdown boundaries-validated for single-pulse durations down to 0.1 ms and DC operation up to 120 V and 15 A.

It exhibits a minimum h_FE of 5.0 at I_C = 10 A and V_CE = 4.0 V, V_CE(sat) ≤ 5.0 V at I_C = 15 A and I_B = 7.0 A, and V_BE(on) between 0.7–1.8 V under rated conditions-enabling predictable drive requirements in discrete power stage designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	120 Vdc - Maximum collector-emitter voltage before breakdown under open-base conditions; defines upper rail limit in PNP output stages.
I_C Continuous	15 Adc - Sustained collector current capability; sets thermal design baseline for heatsink sizing and derating above 25 °C.
P_D @ T_C = 25 °C	180 W - Total device dissipation at case temperature 25 °C; requires low R_JC (0.98 °C/W) path to heatsink.
f_T	6.0 MHz - Current-gain bandwidth product at I_C = 1.0 A, V_CE = 4.0 V; enables stable audio-frequency amplification without oscillation.
R_JC	0.98 °C/W - Junction-to-case thermal resistance; determines temperature rise per watt dissipated across the metal case interface.
h_FE Min	5.0 @ I_C = 10 A, V_CE = 4.0 V - Minimum DC current gain at high current; informs base drive current budget in power amplifier designs.

Pinout & Package

Package: TO-204 (TO-3), hermetically sealed metal case with integral collector connection to case. Dimensions per Case 1-07, Style 1: Pin 1 = Base, Pin 2 = Emitter, Case = Collector.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Base)	Control terminal	Receives forward-biased current to turn on conduction; requires driver capable of sourcing ≥7.0 A peak for saturation at full load.
Pin 2 (Emitter)	Current source terminal	Serves as high-side output node in PNP emitter-follower or common-emitter configurations; referenced to positive supply rail.
Case (Collector)	Power return terminal	Electrically connected to collector; must be electrically isolated from heatsink unless circuit topology permits common-collector grounding.

Key Features

Feature	Design Value
Safe Operating Area (SOA)	Validated for DC, 1 ms, 100 ms, and 0.1 ms pulses up to 120 V/15 A-enables reliable operation in Class AB audio output stages without secondary breakdown.
Second Breakdown Robustness	Rated IS/b = 3.0 Adc at V_CE = 120 V, t = 0.5 s non-repetitive-supports transient overload handling in motor drive and relay switching.
Pb-Free & RoHS Compliant	G-suffix indicates lead-free termination and RoHS compliance-meets environmental requirements for industrial and commercial end equipment.
High Power Dissipation	180 W rating with 0.98 °C/W R_JC-allows compact thermal design when mounted to properly sized heatsink with thermal interface material.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJ15024G	Higher V_CEO (200 V), same I_C (15 A), lower f_T (3.5 MHz), TO-204 package	Better suited for higher bus voltage applications (e.g., 100–160 V DC supplies); reduced bandwidth may limit audio fidelity.	Select MJ15024G when V_CE stress exceeds 120 V but thermal and current demands match MJ15016G.
2N6259	Lower V_CEO (80 V), same I_C (15 A), higher h_FE (min 15 @ 4 A), TO-3 package	Optimized for medium-voltage switching where gain and saturation voltage are prioritized over SOA at high V_CE.	Choose 2N6259 for cost-sensitive 24–48 V systems where 120 V headroom is unnecessary and base drive efficiency matters.

Compared with MJ15024G and 2N6259, the MJ15016G offers the optimal balance of 120 V blocking, 15 A current, and 6.0 MHz f_T for high-fidelity audio and mid-voltage motor control-making it the reference PNP in the onsemi complementary power transistor family despite discontinuation status.

FAQ

Is MJ15016G still in production?

No, the MJ15016G is officially marked as discontinued by onsemi as of January 2026 (Rev. 9 datasheet). However, Aetrix Electronics maintains active inventory and provides traceable, tested legacy stock with full documentation and lifecycle support for ongoing production and repair programs.

What is the pin configuration of MJ15016G?

The MJ15016G uses TO-204 (TO-3) metal package Style 1: Pin 1 is Base, Pin 2 is Emitter, and the metal case is Collector. This configuration is standardized across onsemi's complementary power transistor series and verified in the official mechanical outline diagram (Case 1-07).

Can MJ15016G be used as a direct replacement for MJ15015G?

No-MJ15016G is a PNP transistor while MJ15015G is NPN; they are complementary, not interchangeable. In push-pull amplifier designs, MJ15016G must be paired with MJ15015G (or equivalent NPN) to form a matched high-power output stage with symmetrical SOA and gain characteristics.

What thermal interface is recommended for MJ15016G?

For MJ15016G, use a thermally conductive, electrically insulating interface such as silicone-based thermal grease (e.g., Dow Corning TC-5122) or mica washer with compound, ensuring <0.5 °C·in²/W total thermal resistance from junction to ambient. Mounting torque must comply with TO-3 specifications (typically 12–15 in-lb) to maintain R_JC = 0.98 °C/W.

Does MJ15016G require a base resistor in linear operation?

Yes-MJ15016G requires external base current limiting in all operating modes. For linear amplification, a precision emitter-degenerated bias network is recommended; for switching, a low-impedance driver with ≥7.0 A peak sourcing capability and series base resistor (calculated per V_BE(on) and required I_B) ensures stable saturation and prevents thermal runaway.
