Product details
Overview
NJVMJD31CT4G-VF01 from onsemi is an automotive-grade NPN power transistor in DPAK (TO-252) package, rated for 100 VCEO, 3 A continuous collector current, and 15 W power dissipation at TC = 25 °C. It delivers hFE ≥ 10 at IC = 3 A, VCE = 4 V, and VCE(sat) ≤ 1.2 V under same conditions-designed for low-speed switching and linear amplification in motor drivers, power supplies, and industrial control circuits.
For engineers reviewing the NJVMJD31CT4G-VF01 datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, 100 V breakdown rating, thermal resistance RθJC = 8.3 °C/W, Pb-free DPAK-3 footprint, and compatibility with legacy TIP31C designs in surface-mount power stages.
Technical Context
This device operates as a silicon bipolar junction transistor with complementary PNP counterpart NJVMJD32CT4G-VF01. Its safe operating area supports single-pulse currents up to 3 A at VCE ≤ 10 V and DC operation up to 3 A with proper heatsinking. The fT = 3 MHz bandwidth enables stable gain in audio-frequency amplifiers and PWM-driven loads.
Designed for surface-mount assembly in plastic tape-and-reel (2,500 units), it features straight leads per Style 1 pinout and meets UL 94 V-0 flammability standard. The NJV prefix confirms AEC-Q101 qualification, PPAP capability, and controlled manufacturing site traceability for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Withstands 100 V collector-emitter voltage before breakdown; suitable for 48 V and 72 V industrial bus systems. |
| IC (continuous) | 3.0 A - Supports sustained load current up to 3 A with adequate PCB copper area or heatsink. |
| PD @ TC = 25 °C | 15 W - Maximum junction-to-case power dissipation; requires thermal pad and ≥165 mm² 1 oz. Cu for full rating. |
| hFE @ IC = 3 A | 10–50 - Provides predictable DC current gain for base drive design in switching regulators and relay drivers. |
| VCE(sat) @ IC = 3 A | ≤1.2 V - Low saturation voltage minimizes conduction loss and heat generation in high-current switches. |
| RθJC | 8.3 °C/W - Enables precise junction temperature estimation when mounted to heatsink or thermally enhanced PCB. |
| AEC-Q101 Qualified | Yes - Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires current-limited drive (IB ≤ 1.0 A) for reliable saturation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD31CT4G | No NJV prefix; not AEC-Q101 qualified or PPAP capable; identical electrical specs and DPAK-3 package. | Suitable for commercial/industrial use only; excluded from automotive BOMs requiring certified traceability. | Select NJVMJD31CT4G-VF01 when automotive qualification, site-controlled manufacturing, or PPAP submission is required. |
| TIP31C | TO-220 through-hole package; higher RθJA (65 °C/W vs. 80 °C/W); same VCEO/IC/hFE ratings. | Requires PCB hole drilling and manual assembly; less suitable for automated SMT lines or compact layouts. | Choose NJVMJD31CT4G-VF01 for surface-mount production, thermal efficiency, and automotive compliance. |
Compared with MJD31CT4G and TIP31C, NJVMJD31CT4G-VF01 provides identical power switching performance while adding AEC-Q101 validation, controlled manufacturing traceability, and optimized DPAK thermal interface-making it the sole choice for automotive SMT power stages where reliability and compliance are mandatory.

FAQ
What is the maximum junction temperature for NJVMJD31CT4G-VF01?
The NJVMJD31CT4G-VF01 has an operating junction temperature range of −65 °C to +150 °C. This rating is confirmed in the Maximum Ratings table of the official datasheet (Rev. 21, May 2026). Exceeding +150 °C risks permanent degradation of the silicon die and bond wires. Thermal design must ensure TJ remains within this limit under worst-case ambient and power dissipation conditions.
Is NJVMJD31CT4G-VF01 pin-compatible with MJD31CT4G?
Yes, NJVMJD31CT4G-VF01 is pin-compatible with MJD31CT4G: both use identical DPAK-3 (Case 369C) packaging and Style 1 pinout (Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector). The NJV prefix adds AEC-Q101 qualification and controlled site traceability but does not alter mechanical or electrical pin mapping.
What is the typical DC current gain (hFE) of NJVMJD31CT4G-VF01 at 3 A collector current?
The NJVMJD31CT4G-VF01 exhibits hFE ≥ 10 at IC = 3 A, VCE = 4 V, and TC = 25 °C, per the Electrical Characteristics table. At lower currents (e.g., IC = 1 A), hFE increases to ≥25. This gain behavior is verified across temperature ranges from −55 °C to +150 °C in Figures 6 and 7 of the datasheet.
Does NJVMJD31CT4G-VF01 support lead-free reflow soldering?
Yes, NJVMJD31CT4G-VF01 is Pb-free and RoHS compliant, with a maximum lead temperature rating of 260 °C for soldering. Its "G" suffix and UL 94 V-0 epoxy ensure compatibility with standard lead-free reflow profiles. The device is qualified for JEDEC J-STD-020 moisture sensitivity level (MSL) 1, permitting unlimited floor life at ≤30 °C/60% RH.
How does the thermal resistance RθJC of NJVMJD31CT4G-VF01 impact PCB layout?
The NJVMJD31CT4G-VF01 has RθJC = 8.3 °C/W when mounted to a minimum 165 mm², 1 oz. Cu thermal pad per datasheet Note 1. To achieve this value, the PCB must expose the collector pads (pins 2 and 4) to a solid copper pour connected to internal ground or thermal planes. Insufficient copper area raises effective RθJC, risking thermal runaway at full 3 A load.
