Product details
Overview
NJVMJD31CG from onsemi is an AEC-Q101 qualified NPN complementary power transistor in DPAK (Case 369C) package, rated for 100 VCEO, 3 A continuous collector current, and 15 W total power dissipation at TC = 25 °C. It serves as a general-purpose amplifier and low-speed switching device in automotive power supplies, motor drivers, and industrial linear regulators.
For engineers reviewing the NJVMJD31CG datasheet, pinout, applications, or equivalent options, key selection criteria include its 100 V breakdown rating, 25–50 hFE at 1 A, 1.2 V VCE(sat) at 3 A/375 mA drive, thermal resistance of 8.3 °C/W (junction-to-case), and Pb-free, RoHS-compliant DPAK surface-mount construction.
Technical Context
This NPN bipolar junction transistor operates with a minimum DC current gain (hFE) of 25 at IC = 1 A and VCE = 4 V, and supports peak collector current up to 5 A. Its fT is 3 MHz under standard test conditions (IC = 500 mA, VCE = 10 V), confirming suitability for audio-frequency amplification and <100 kHz switching.
The device features a dual-collector DPAK-3 configuration (pins 2 and 4 both connected to collector), enabling enhanced thermal conduction and current handling. Junction temperature range spans −65 °C to +150 °C, and it meets UL 94 V−0 flammability rating with epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD31CG | No NJV prefix; not AEC-Q101 qualified; identical electrical specs and DPAK package. | Suitable for non-automotive industrial or consumer applications where PPAP documentation is not required. | Select MJD31CG for cost-sensitive non-automotive designs needing same performance without automotive traceability. |
| TIP31C | TO-220 package (larger footprint, higher RθJA); same VCEO, IC, hFE, but no AEC-Q101 qualification or dual-collector thermal advantage. | Requires through-hole assembly and external heatsink; less suitable for space-constrained automotive PCBs. | Choose TIP31C only for legacy through-hole designs or prototyping where DPAK reflow is unavailable. |
Compared with NJVMJD31CG, MJD31CG offers identical electrical behavior at lower cost but lacks automotive qualification, while TIP31C provides mechanical compatibility with older designs but sacrifices surface-mount efficiency and thermal performance.

FAQ
What is the maximum collector-emitter voltage rating for NJVMJD31CG?
The NJVMJD31CG has a maximum collector-emitter sustaining voltage (VCEO(sus)) of 100 Vdc at IC = 30 mA and IB = 0. This rating is confirmed in the Maximum Ratings table and Electrical Characteristics section of the official onsemi datasheet (MJD31/D, Rev. 21). The device maintains this breakdown voltage across its full operating temperature range of −65 °C to +150 °C.
Is NJVMJD31CG pin-compatible with standard TIP31C transistors?
No - NJVMJD31CG uses a DPAK-3 surface-mount package with pins 1 (base), 2 & 4 (collector), and 3 (emitter), whereas TIP31C uses a TO-220 through-hole package with different pinout and mechanical dimensions. While NJVMJD31CG is electrically similar to TIP31C, it is not pin-compatible due to distinct packaging and terminal configuration.
Does NJVMJD31CG require a heatsink in typical applications?
NJVMJD31CG can operate without an external heatsink when dissipating ≤1.56 W at ambient temperature (TA = 25 °C), based on its RθJA = 80 °C/W rating. For higher-power applications (e.g., >2 A continuous conduction), a PCB copper pour or small heatsink is recommended - its RθJC = 8.3 °C/W enables efficient thermal transfer when mounted on minimum 165 mm² copper area.
What does the "NJV" prefix signify in NJVMJD31CG?
The "NJV" prefix in NJVMJD31CG indicates automotive-grade manufacturing with unique site and process control change requirements. It denotes AEC-Q101 qualification, PPAP capability, and traceable lot-level documentation - distinguishing it from standard MJD31CG, which shares identical electrical specs but lacks automotive certification.
Can NJVMJD31CG be used in complementary pair configurations?
Yes - NJVMJD31CG (NPN) is explicitly designed as part of a complementary pair with NJVMJD32CG (PNP), sharing identical DPAK-3 packaging, thermal characteristics, and automotive qualification. Their matched VCEO, IC, and hFE profiles enable balanced Class AB amplifier stages and full-bridge motor drivers without thermal or gain mismatch concerns.
