Product details
Overview
NJVMJD44H11RLG-VF01 from onsemi is an NPN complementary power transistor in DPAK (Case 369C) surface-mount package, rated for 80 VCEO, 8 A continuous collector current, and 20 W power dissipation at TC = 25 °C. It delivers low 1 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 DC-DC switching regulators and motor driver circuits.
For engineers reviewing the NJVMJD44H11RLG-VF01 datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, 6.25 °C/W junction-to-case thermal resistance, complementary pairing with MJD45H11, and Pb-free RoHS-compliant DPAK-3 footprint for automotive-grade power switching designs.
Technical Context
This NPN bipolar junction transistor operates in linear and saturated switching modes, with hFE ≥ 60 at IC = 2 A and VCE = 1 V. Its safe operating area (SOA) is defined up to 150 °C junction temperature and constrained by both thermal limits and second breakdown, validated under pulsed conditions per Figure 2 of the datasheet.
The device features electrically similar characteristics to the legacy D44H series, supports surface-mount assembly with lead-formed or straight-lead variants, and meets UL 94 V-0 flammability rating at 0.125 in thickness. Its 45 pF Ccb and 85 MHz fT enable stable high-frequency switching in converter topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum collector-emitter voltage before breakdown; defines maximum bus voltage compatibility in switching regulators. |
| IC (continuous) | 8 A - Continuous collector current handling capacity; supports medium-power motor drive and SMPS output stages. |
| PD @ TC = 25 °C | 20 W - Power dissipation limit at case temperature 25 °C; requires heatsinking for sustained operation above ambient. |
| VCE(sat) | 1 V max at IC = 8 A / IB = 0.4 A - Low saturation voltage reduces conduction losses and improves efficiency in hard-switched applications. |
| fT | 85 MHz - Current-gain-bandwidth product; enables reliable operation in PWM frequencies up to several MHz with adequate gain margin. |
| RθJC | 6.25 °C/W - Junction-to-case thermal resistance; determines minimum heatsink requirement when mounted on PCB copper pads per datasheet layout guidelines. |
| AEC-Q101 | Qualified - Validated for automotive underhood applications including temperature cycling, HTRB, and ESD testing per stress test conditions. |
Pinout & Package
DPAK-3 (Case 369C) surface-mount package, 6.10 mm × 6.54 mm × 2.28 mm body size with 2.29 mm lead pitch. Features exposed drain pad (pin 2 & 4) for thermal and electrical connection to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires ~0.4 A base drive for full saturation at 8 A collector current. |
| 2 | Collector | Main high-side current path; electrically tied to pin 4 and thermally connected to exposed pad for heatsinking. |
| 3 | Emitter | Current return path; common reference node for base drive and load connection in common-emitter configurations. |
| 4 | Collector | Second collector terminal; paralleled with pin 2 to reduce bond wire inductance and improve current sharing in high-dI/dt switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including temperature cycling, HTRB, and ESD per JESD22-A114 (HBM Class 3B). |
| Low VCE(sat) | ≤1 V at 8 A ensures <1 W conduction loss per device, critical for thermal management in compact power modules. |
| Fast switching | td + tr = 300 ns / tf = 140 ns enables >100 kHz PWM operation with minimal switching loss in buck converters. |
| Complementary pair | Designed to match MJD45H11 (PNP) for push-pull and H-bridge driver stages without custom biasing networks. |
| Pb-free & RoHS | Meets EU RoHS Directive 2011/65/EU and halogen-free/BFR-free requirements for environmentally compliant manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD44H11RLG | No NJV prefix; not AEC-Q101 qualified; same electrical specs and DPAK-3 package. | Suitable for industrial/non-automotive applications where PPAP and automotive qualification are not required. | Select NJVMJD44H11RLG-VF01 when automotive compliance, traceable sourcing, and PPAP documentation are mandatory. |
| STN8300 | 80 V VCEO, 8 A IC, but higher VCE(sat) (1.5 V typ), lower fT (50 MHz), and no AEC-Q101 certification. | Acceptable for cost-sensitive industrial SMPS where switching speed and automotive reliability are secondary. | Choose NJVMJD44H11RLG-VF01 over STN8300 when fast switching, low saturation loss, and automotive qualification are design-critical. |
Compared with MJD44H11RLG and STN8300, NJVMJD44H11RLG-VF01 provides verified AEC-Q101 qualification, identical pinout and thermal performance, and superior switching speed-making it the only option qualified for automotive underhood deployment without derating or requalification.

FAQ
What is the maximum junction temperature rating for NJVMJD44H11RLG-VF01?
The NJVMJD44H11RLG-VF01 has an operating junction temperature range of −55 °C to +150 °C, as specified in the Maximum Ratings table. This allows use in underhood automotive environments and industrial enclosures with elevated ambient temperatures, provided thermal design maintains TJ ≤ 150 °C using the 6.25 °C/W RθJC value and appropriate PCB copper area.
Is NJVMJD44H11RLG-VF01 pin-compatible with standard MJD44H11 devices?
Yes, NJVMJD44H11RLG-VF01 uses the same DPAK-3 (Case 369C) package and identical 4-pin pinout (Base, Collector, Emitter, Collector) as MJD44H11RLG and MJD44H11G. The NJV prefix denotes automotive qualification and unique site control but does not alter mechanical or electrical pin assignments.
Does NJVMJD44H11RLG-VF01 require a heatsink in typical applications?
NJVMJD44H11RLG-VF01 can operate without an external heatsink when mounted on ≥1 in² of 2-oz copper with thermal vias, leveraging its 6.25 °C/W RθJC. For continuous 8 A operation at ambient >50 °C, a small clip-on heatsink or increased copper area is recommended to maintain TJ < 130 °C per SOA derating curves.
What is the significance of the "VF01" suffix in NJVMJD44H11RLG-VF01?
The "VF01" suffix identifies a specific onsemi internal variant code indicating tape-and-reel packaging (1,800 units per reel), automotive qualification traceability, and controlled manufacturing lot release. It does not alter electrical specifications but confirms compliance with PPAP documentation and AEC-Q101 test reports for that production batch.
Can NJVMJD44H11RLG-VF01 be used in linear amplifier applications?
Yes, NJVMJD44H11RLG-VF01 supports linear operation with hFE ≥ 60 at IC = 2 A and VCE = 1 V, and its SOA curve (Figure 2) validates safe operation up to 100 V × 0.5 A in DC conditions. However, thermal management must account for 1.75 W dissipation at TA = 25 °C to avoid exceeding TJ = 150 °C.
