Product details
Overview
NJVMJD44H11T4G from onsemi is an AEC-Q101-qualified NPN power bipolar junction transistor in DPAK (TO-252) package, rated for 80 V VCEO, 8 A continuous collector current, and 20 W power dissipation at TC = 25 °C. It delivers low 1 V typical VCE(sat) at IC = 8 A / IB = 0.4 A and supports fast switching with td + tr = 300 ns, making it suitable for output stages in automotive DC-DC converters and industrial motor drivers.
For engineers reviewing the NJVMJD44H11T4G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, complementary pairing with NJVMJD45H11T4G, surface-mount DPAK thermal performance (RJC = 6.25 °C/W), and verified safe operating area up to 150 °C junction temperature.
Technical Context
This NPN transistor employs epitaxial base construction for stable hFE across temperature and load, with minimum DC current gain of 60 at IC = 2 A and 40 at IC = 4 A under VCE = 1 V. Its 85 MHz fT and 45 pF Ccb support medium-frequency switching in hard-switched topologies.
The device operates within −55 °C to +150 °C junction range and features UL 94 V-0 compliant epoxy encapsulation. Its DPAK package enables direct heatsinking via the exposed collector tab (pins 2 and 4), while the dual-collector configuration improves current handling and thermal spreading versus standard TO-220 equivalents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum blocking voltage between collector and emitter with base open; defines upper limit for switch-mode power stage bus voltage compatibility. |
| IC (continuous) | 8 A - Continuous DC collector current capability at TC = 25 °C; determines maximum steady-state load drive capacity. |
| PD @ TC = 25 °C | 20 W - Total power dissipation limit when case temperature is maintained at 25 °C; requires external heatsink for full-load operation. |
| VCE(sat) | 1 V max at IC = 8 A / IB = 0.4 A - Low saturation voltage minimizes conduction loss in linear and switching applications. |
| fT | 85 MHz - Current-gain-bandwidth product; sets usable frequency limit for small-signal amplification and high-speed switching control. |
| RJC | 6.25 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing when mounting to PCB copper or metal core. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HBM ESD (3B), and lifetime stress testing per JEDEC standards. |
Pinout & Package
DPAK-3 (Case 369C) surface-mount package with exposed collector tab (pins 2 and 4), 6.10 × 6.54 × 2.28 mm footprint, and Pb-free (RoHS-compliant) finish. Thermal pad must be soldered to ≥100 mm² copper pour for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires ≥0.4 A base drive for full 8 A collector conduction; low-impedance path to internal base region. |
| 2 | Collector | Main high-current output terminal; electrically connected to exposed metal tab for direct thermal coupling to PCB heatsink. |
| 3 | Emitter | Current return path; referenced to system ground in common-emitter configurations; carries full load current. |
| 4 | Collector | Second collector connection-parallel to pin 2-to reduce bond wire inductance and improve current sharing in high-di/dt switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive power electronics including engine control modules and body electronics requiring PPAP documentation. |
| Dual-collector DPAK structure | Reduces effective on-resistance and thermal impedance by distributing current across two parallel collector paths and the exposed tab. |
| Low VCE(sat) (1 V max) | Enables <1.6 W conduction loss at 8 A, improving efficiency in 12 V/24 V automotive switching regulators and motor drivers. |
| Fast switching (td+tr = 300 ns) | Supports PWM frequencies up to ~300 kHz without excessive switching loss, suitable for compact flyback and buck converter designs. |
| UL 94 V-0 epoxy | Meets flammability requirements for enclosed automotive and industrial enclosures without additional potting or shielding. |
Applications
| Automotive DC-DC Converters | Industrial Motor Drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD44H11T4G | No NJV prefix; not AEC-Q101 qualified; identical electrical specs and DPAK-3 package. | Suitable for industrial/commercial use only; lacks automotive traceability and PPAP support. | Select when automotive qualification is unnecessary and cost sensitivity is higher. |
| STN8300 | 80 V VCEO, 8 A IC, but lower fT (30 MHz) and higher VCE(sat) (1.5 V typ); TO-252 package with single collector pin. | Limited to ≤100 kHz switching; less efficient in high-frequency converters due to slower gain-bandwidth response. | Choose for legacy designs where pin compatibility is required but AEC-Q101 is not mandated. |
Compared with MJD44H11T4G, NJVMJD44H11T4G adds automotive qualification and process traceability without sacrificing electrical performance; versus STN8300, it offers superior switching speed and lower conduction loss, enabling smaller magnetics and cooler operation in space-constrained automotive modules.

FAQ
What is the maximum junction temperature rating for NJVMJD44H11T4G?
The NJVMJD44H11T4G has an operating junction temperature range of −55 °C to +150 °C, as specified in the Absolute Maximum Ratings table. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings when mounted on adequately sized copper heatsinks per the recommended pad layout.
Does NJVMJD44H11T4G require a heatsink in all applications?
Yes-NJVMJD44H11T4G requires thermal management to maintain safe junction temperature. At full 8 A continuous current and 20 W dissipation, its RJC = 6.25 °C/W necessitates a heatsink or large PCB copper area to keep TJ ≤ 150 °C. Derating curves in Figure 3 show power must be reduced above 25 °C case temperature.
Is NJVMJD44H11T4G pin-compatible with MJD44H11T4G?
Yes-NJVMJD44H11T4G uses the identical DPAK-3 (Case 369C) package with matching pin 1 (base), pin 2 (collector), pin 3 (emitter), and pin 4 (collector) layout. Mechanical drawings confirm identical footprint, pad dimensions, and thermal tab geometry, enabling drop-in replacement where AEC-Q101 qualification is not required.
What is the Safe Operating Area (SOA) limitation for NJVMJD44H11T4G at 100 °C case temperature?
At TC = 100 °C, NJVMJD44H11T4G's SOA is constrained by second breakdown and thermal limits. Per Figure 2, maximum allowable IC drops to ~4.5 A at VCE = 40 V for DC operation, and further decreases for pulse durations >1 ms. Designers must consult the normalized transient thermal curve (Figure 1) for pulsed conditions.
Can NJVMJD44H11T4G be used in complementary pair configurations?
Yes-NJVMJD44H11T4G is explicitly designed as the NPN complement to NJVMJD45H11T4G (PNP). Both share matched VCEO, IC, VCE(sat), and thermal characteristics, simplifying push-pull, H-bridge, and class AB amplifier designs without cross-conduction risk or gain mismatch.
