Product details
Overview
NJVMJD31CRLG from onsemi is an NPN complementary power transistor in DPAK (Case 369C) surface-mount package, rated for 100 VCEO, 3 A continuous collector current, and 15 W power dissipation at TC = 25 °C. It serves as a general-purpose amplifier and low-speed switching device in automotive and industrial power stages, including linear regulators and relay drivers.
For engineers reviewing the NJVMJD31CRLG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, 100 V breakdown rating, 1.2 V typical VCE(sat) at 3 A/375 mA, thermal resistance of 8.3 °C/W (junction-to-case), and Pb-free RoHS-compliant DPAK packaging.
Technical Context
This NPN bipolar junction transistor operates with DC current gain (hFE) of 10–50 at IC = 3 A and VCE = 4 V, and delivers fT = 3 MHz at IC = 500 mA, VCE = 10 V. Its safe operating area supports single-pulse operation up to 3 A at 100 V with 1 ms pulse width.
The device features electrically similar characteristics to the TIP31 series but with enhanced voltage rating and automotive-grade qualification. It exhibits VBE(on) ≤ 1.8 V at IC = 3 A and maintains ICEO ≤ 50 µA at VCE = 100 V, ensuring stable cutoff behavior under high-voltage bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Maximum collector-emitter voltage before avalanche breakdown; enables use in 48 V and higher industrial bus applications. |
| IC (continuous) | 3.0 A - Sustained collector current capability; supports medium-power switching without forced cooling at moderate duty cycles. |
| PD @ TC = 25 °C | 15 W - Power dissipation limit when mounted on minimum recommended copper pad (165 mm², 1 oz Cu); defines thermal design baseline. |
| VCE(sat) | ≤1.2 V @ IC = 3 A, IB = 375 mA - Low saturation voltage reduces conduction loss in linear and switching modes. |
| hFE | 10–50 @ IC = 3 A, VCE = 4 V - Confirmed DC current gain range ensures predictable base drive requirements. |
| RθJC | 8.3 °C/W - Junction-to-case thermal resistance; critical for heatsink interface design in surface-mount power stage layouts. |
| AEC-Q101 | Qualified - Validated for automotive temperature cycling, humidity, and mechanical stress; supports PPAP documentation. |
Pinout & Package
DPAK (Case 369C) surface-mount package with 4-terminal configuration: thermally enhanced die attach via exposed collector tab (Pins 2 and 4), standard leadframe layout optimized for PCB heat spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires ≥375 mA base drive for full saturation at 3 A collector current. |
| 2 | Collector | Main high-current output node; electrically connected to exposed metal tab for thermal and electrical path to heatsink or ground plane. |
| 3 | Emitter | Reference terminal for current flow; tied to system ground or low-side return in common-emitter configurations. |
| 4 | Collector | Second collector connection-internally bonded to Pin 2; must be soldered to same copper pour for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments (-40 °C to +150 °C junction); supports PPAP submission for OEM programs. |
| 100 V VCEO rating | Enables direct use in 72 V battery systems and industrial 100 V rail applications without derating or series stacking. |
| DPAK tape-and-reel (1800 pcs) | Optimized for automated SMT placement; eliminates manual handling and supports high-volume production line integration. |
| Pb-free and RoHS compliant | Meets global environmental regulations; compatible with lead-free reflow profiles up to 260 °C peak solder temperature. |
| UL 94 V-0 epoxy | Flame-retardant encapsulation meets safety standards for enclosed power modules and industrial control cabinets. |

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 | Same silicon, identical electrical specs, but supplied in 2500-piece tape-and-reel (T4 suffix) instead of 1800-piece RLG format. | No functional difference; selected when larger reel size aligns with SMT line changeover intervals or procurement batch sizing. | Direct form-fit-function replacement; no layout or thermal redesign required. |
| TIP31C | Through-hole TO-220 package; same 100 V/3 A rating but higher RθJA (65 °C/W vs. 80 °C/W for NJVMJD31CRLG at TA), no AEC-Q101 qualification. | Suitable for prototyping or low-volume non-automotive designs where manual assembly or legacy footprint compatibility is prioritized. | Not drop-in: requires PCB redesign, lacks automotive qualification, and has inferior thermal performance in surface-mount assemblies. |
Compared with NJVMJD31CRLG, MJD31CT4G offers identical performance in a different reel size, while TIP31C provides legacy through-hole compatibility at the cost of thermal efficiency and automotive compliance-making NJVMJD31CRLG the preferred choice for new AEC-Q101-compliant SMT power designs.

FAQ
What is the maximum collector-emitter voltage rating for NJVMJD31CRLG?
The NJVMJD31CRLG 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 rating across its full operating temperature range and is validated for transient overvoltage events in automotive applications.
Is NJVMJD31CRLG qualified for automotive applications?
Yes, NJVMJD31CRLG carries the NJV prefix indicating it is AEC-Q101 qualified and PPAP capable. The datasheet explicitly states "NJV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q101 Qualified and PPAP Capable." This qualification covers temperature cycling, mechanical shock, and humidity testing per AEC-Q101 standards.
What package type and mounting style does NJVMJD31CRLG use?
NJVMJD31CRLG uses the DPAK (Case 369C) surface-mount package with four terminals: Base (Pin 1), Collector (Pins 2 and 4), and Emitter (Pin 3). The exposed collector tab (Pins 2 and 4) serves as both electrical connection and primary thermal path, requiring soldering to a large copper pour for effective heat dissipation.
What is the typical VCE(sat) of NJVMJD31CRLG under full-load conditions?
The typical collector-emitter saturation voltage (VCE(sat)) for NJVMJD31CRLG is ≤1.2 Vdc when IC = 3 Adc and IB = 375 mAdc, as specified in the Electrical Characteristics table. This value is measured at TC = 25 °C and reflects the device's low conduction loss in saturated switching mode, critical for efficiency in linear regulators and relay drivers.
How does NJVMJD31CRLG differ from the standard MJD31CRLG part number?
NJVMJD31CRLG differs from MJD31CRLG solely in manufacturing site control and traceability: the "NJV" prefix denotes production at an onsemi facility meeting unique automotive site requirements, including enhanced process controls and PPAP documentation readiness. Electrically and mechanically, NJVMJD31CRLG is identical to MJD31CRLG per the datasheet ordering information table.
