Product details

Overview

NJVMJD44H11G from onsemi is an AEC-Q101 qualified NPN silicon power transistor in DPAK (Case 369C) package, rated for 80 V_CEO, 8 A continuous collector current, and 20 W power dissipation at T_C = 25 °C. It delivers low 1 V_CE(sat) at I_C = 8 A / I_B = 0.4 A and supports fast switching with t_d + t_r = 300 ns, making it suitable for output stages in automotive DC-DC converters and industrial motor drivers.

For engineers reviewing the NJVMJD44H11G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, complementary pairing with NJVMJD45H11G, thermal resistance R_θJC = 6.25 °C/W, and suitability for surface-mount switching regulator output stages requiring robust SOA and low saturation voltage.

Technical Context

This NPN bipolar junction transistor operates in linear or saturated switching modes with a minimum h_FE of 60 at I_C = 2 A and V_CE = 1 V. Its safe operating area (SOA) is defined up to 150 °C junction temperature, with second-breakdown limits validated for pulse duty cycles ≤10%.

Designed for surface-mount use in DPAK, it features Pb-free, halogen-free construction compliant with RoHS and UL 94 V-0 epoxy. The NJV prefix confirms automotive-grade traceability, PPAP capability, and site-specific control per AEC-Q101 requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum collector-emitter blocking voltage before breakdown under open-base conditions.
I_C (cont.)	8 A - Continuous collector current rating at T_C = 25 °C; derates linearly above 25 °C (0.16 W/°C).
V_CE(sat)	1 V - Collector-emitter saturation voltage at I_C = 8 A and I_B = 0.4 A; enables low conduction loss in switching applications.
f_T	85 MHz - Current-gain-bandwidth product at I_C = 0.5 A, V_CE = 10 V; supports high-frequency switching up to ~10–20 MHz.
R_θJC	6.25 °C/W - Junction-to-case thermal resistance; requires heatsinking via PCB copper pad to maintain T_J ≤ 150 °C.
t_d + t_r	300 ns - Total delay + rise time at I_C = 5 A, I_B1 = 0.5 A; defines minimum practical switching period in hard-switched topologies.
AEC-Q101	Qualified - Validated for automotive temperature cycling, HTRB, ESD (HBM Class 3B), and lifetime reliability per stress test standards.

Pinout & Package

DPAK (Case 369C) surface-mount package with 4-terminal configuration: thermally enhanced exposed collector tab (pins 2 and 4), base (pin 1), and emitter (pin 3). Dimensions: 6.10 × 6.54 × 2.28 mm, pitch 2.29 mm.

Pin/Terminal	Circuit Role	Design Meaning

2 & 4	Collector	Electrically common high-current output terminals; both connected to exposed copper tab for thermal and electrical conduction.
3	Emitter	Reference terminal for base drive and load return path; carries full load current in common-emitter configuration.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive under-hood environments including temperature cycling, high-temp reverse bias, and ESD robustness.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD44H11G	No NJV prefix; standard commercial grade, not AEC-Q101 qualified or PPAP capable.	Lacks automotive traceability and extended reliability testing; unsuitable for OEM automotive programs.	Select NJVMJD44H11G when AEC-Q101 compliance, PPAP documentation, or unique site control is required.
STN8300	80 V_CEO, 8 A, but TO-220 package (R_θJA ≈ 65 °C/W vs. DPAK's 71.4 °C/W); h_FE min = 40 at 4 A.	Through-hole mounting only; higher thermal resistance requires larger heatsink; lower gain demands stronger base drive.	Choose STN8300 only if legacy through-hole assembly is mandatory and thermal budget allows higher R_θJA.

Compared with MJD44H11G and STN8300, NJVMJD44H11G uniquely combines automotive qualification, DPAK surface-mount compatibility, and matched complementary pairing-enabling smaller footprint, better thermal coupling to PCB, and direct integration into AEC-compliant power designs without redesign.

FAQ

What is the maximum junction temperature rating for NJVMJD44H11G?

The NJVMJD44H11G has an operating junction temperature range of −55 °C to +150 °C, as specified in the Absolute Maximum Ratings table. This rating is validated under AEC-Q101 stress testing and applies to both continuous and pulsed operation when thermal design maintains T_J within limits using the stated R_θJC = 6.25 °C/W and recommended PCB pad layout.

Is NJVMJD44H11G pin-compatible with MJD44H11G?

Yes, NJVMJD44H11G is pin-compatible with MJD44H11G - both use identical DPAK (Case 369C) packaging with the same 4-pin layout (Base, Collector, Emitter, Collector). However, NJVMJD44H11G adds AEC-Q101 qualification, PPAP capability, and NJV-prefix traceability, while MJD44H11G is commercial-grade only.

What base drive current is required to saturate NJVMJD44H11G at 8 A collector current?

To achieve V_CE(sat) ≤ 1 V at I_C = 8 A, the NJVMJD44H11G requires I_B = 0.4 A, as tested per the Electrical Characteristics table. For reliable saturation across temperature and process variation, design with ≥0.5 A base drive and verify with worst-case h_FE (min 40 at I_C = 4 A) in final circuit validation.

Does NJVMJD44H11G support complementary operation with a PNP device?

Yes, NJVMJD44H11G is explicitly designed as the NPN complement to NJVMJD45H11G (PNP), sharing identical voltage/current ratings, thermal characteristics, and AEC-Q101 qualification. Their matched parameters simplify push-pull, totem-pole, and half-bridge driver design without external balancing components.

What is the Safe Operating Area (SOA) limit for NJVMJD44H11G at 100 µs pulse width?

Per Figure 2 in the datasheet, the NJVMJD44H11G SOA at 100 µs pulse width supports up to ~60 V_CE at 8 A (DC limit), constrained by second breakdown. At shorter pulses (e.g., 10 µs), it extends to ~80 V at 5 A. Always reference the normalized transient thermal curve (Figure 1) and apply derating for case temperature above 25 °C.
