Product details
Overview
NJVMJD44H11RLG from onsemi is an NPN complementary power transistor in DPAK (Case 369C) surface-mount package, rated for 8 A continuous collector current, 80 V collector-emitter voltage, and 20 W power dissipation at TC = 25 °C. It delivers low VCE(sat) of ≤1 V at IC = 8 A/IB = 0.4 A and fast switching with td + tr ≤300 ns, enabling use in high-efficiency switching regulators and motor driver output stages.
For engineers reviewing the NJVMJD44H11RLG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, Pb-free RoHS-compliant DPAK-3 package, thermal resistance RJC = 6.25 °C/W, and complementary pairing with NJVMJD45H11RLG for push-pull designs.
Technical Context
This device operates as a general-purpose silicon power switch with bipolar junction architecture, optimized for linear and saturated-mode operation in DC-DC converters and audio power amplifiers. Its hFE ranges from 40–60 at IC = 4–2 A, supporting stable current gain across industrial temperature range (−55 °C to +150 °C).
The NJVMJD44H11RLG features low saturation voltage and fast turn-on/turn-off characteristics-ts = 500 ns, tf = 140 ns-enabling efficient pulse-width modulation control. Its safe operating area (SOA) is defined up to 150 °C junction temperature, with second-breakdown limits validated for ≤10% duty cycle pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 Vdc - Withstands up to 80 V between collector and emitter under open-base conditions, suitable for 48 V bus switching applications. |
| IC (cont.) | 8 Adc - Supports continuous load currents up to 8 A without derating when mounted on minimum recommended PCB copper area. |
| VCE(sat) | ≤1 V at IC = 8 A, IB = 0.4 A - Minimizes conduction loss and heat generation in saturated-switching topologies. |
| fT | 85 MHz - Enables stable high-frequency amplifier and switching operation up to mid-VHF range. |
| RJC | 6.25 °C/W - Allows direct thermal path to heatsink via exposed collector pad, critical for maintaining TJ ≤150 °C at full power. |
| hFE | 60 min at IC = 2 A, VCE = 1 V - Ensures sufficient current gain for base-drive efficiency in discrete driver circuits. |
| ESD HBM | Class 3B - Provides robustness against human-body electrostatic discharge during handling and assembly. |
Pinout & Package
DPAK-3 (Case 369C) surface-mount package with exposed collector pad for thermal management; dimensions 6.10 × 6.54 × 2.28 mm, pitch 2.29 mm. Pin 1 = Base, Pins 2 & 4 = Collector (common), Pin 3 = Emitter.
| Pin/Terminal | Circuit Role | 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 |
|---|---|---|---|
| MJD44H11RLG | 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 production programs requiring PPAP documentation. | Select NJVMJD44H11RLG when automotive qualification, traceable sourcing, or change-control compliance is required. |
| STN8300 | Lower VCEO (60 V), higher VCE(sat) (1.2 V typ), same IC (8 A); TO-252 package with different pinout (1=Emitter, 2=Base, 3=Collector). | Not drop-in compatible; requires PCB redesign due to reversed pin assignment and reduced voltage margin. | Choose STN8300 only if 60 V rating suffices and board layout allows TO-252 footprint and routing changes. |
Compared with MJD44H11RLG, NJVMJD44H11RLG adds automotive qualification and controlled manufacturing site tracking, while STN8300 trades voltage headroom and pin compatibility for alternate sourcing-but neither offers the combined AEC-Q101, DPAK-3, and 80 V capability of NJVMJD44H11RLG.

FAQ
What is the maximum junction temperature rating for NJVMJD44H11RLG?
The NJVMJD44H11RLG has an operating junction temperature range of −55 °C to +150 °C, verified per AEC-Q101 stress testing. This allows deployment in under-hood automotive environments and high-ambient industrial enclosures where thermal management is constrained. The device's SOA curves and thermal derating data assume TJ ≤150 °C for reliable long-term operation.
Is NJVMJD44H11RLG pin-compatible with standard MJD44H11 devices?
Yes, NJVMJD44H11RLG uses the identical DPAK-3 (Case 369C) package and pinout: Pin 1 = Base, Pins 2 & 4 = Collector, Pin 3 = Emitter. Mechanical and solder footprint compatibility is maintained with MJD44H11RLG and MJD44H11G, though NJVMJD44H11RLG adds NJV-prefix process controls and AEC-Q101 qualification.
Does NJVMJD44H11RLG require a heatsink in typical applications?
At full 8 A continuous current and 20 W dissipation, NJVMJD44H11RLG requires a heatsink to maintain TJ ≤150 °C-its RJC of 6.25 °C/W means even 10 W dissipation raises junction temperature by 62.5 °C above case. For intermittent loads <3 A, the exposed collector pad may suffice with adequate PCB copper area, but thermal simulation is recommended for each design.
What does the "NJV" prefix signify on NJVMJD44H11RLG?
The "NJV" prefix identifies NJVMJD44H11RLG as manufactured under onsemi's automotive-specific production line with enhanced process controls, unique site tracking, and PPAP documentation readiness. It confirms AEC-Q101 qualification for stress tests including HTSL, TC, and HAST-making it suitable for safety-critical automotive subsystems where standard MJD44H11 variants are not approved.
Can NJVMJD44H11RLG be used in linear amplifier applications?
Yes, NJVMJD44H11RLG is characterized for linear operation with hFE ≥60 at IC = 2 A and VCE = 1 V, and SOA curves covering DC and pulsed conditions. Its low VCE(sat) and stable gain across −55 °C to +150 °C support Class AB audio output stages and precision current-source designs-provided adequate heatsinking and bias stability measures are implemented.
