Product details
Overview
NJVMJD122T4G-VF01 from onsemi is an AEC-Q101-qualified complementary NPN Darlington power transistor in DPAK (TO-252) package, rated for 8 A continuous collector current, 100 V collector-emitter sustaining voltage, and 20 W power dissipation at TC = 25 °C. It features monolithic construction with built-in base-emitter shunt resistors, high DC current gain (hFE = 1000–12,000), and is designed for low-speed switching and general-purpose amplifier applications in automotive and industrial motor control circuits.
For engineers reviewing the NJVMJD122T4G-VF01 datasheet, pinout, applications, or equivalent options, key selection criteria include its 100 V VCEO(sus), 2.0 V typical VCE(sat) at IC = 4 A / IB = 16 mA, integrated base resistors enabling direct microcontroller drive, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
The NJVMJD122T4G-VF01 implements a monolithic Darlington pair with internal base-emitter shunt resistors (≈8 kΩ and ≈120 Ω), eliminating external bias components. Its architecture delivers high hFE (≥1000 at IC = 4 A) while maintaining low saturation voltage and robust thermal performance via DPAK's low RθJC of 6.25 °C/W.
It operates within −65 °C to +150 °C junction temperature range and supports surface-mount assembly with Pb-free, halogen-free, RoHS-compliant packaging. The device meets ESD ratings of >8000 V (HBM Class 3B) and >400 V (MM Class C), ensuring reliability in automated manufacturing and harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO(sus) | 100 V - Sustains full rated voltage with IC = 30 mA and open base, enabling use in 24 V/48 V automotive power stages without derating. |
| IC (continuous) | 8 A - Supports high-current loads such as solenoid drivers, fan motors, and relay coils without external heat sinking at moderate duty cycles. |
| hFE | 1000–12,000 - High DC current gain reduces required base drive current, allowing direct interface with 3.3 V/5 V logic and MCU GPIOs. |
| VCE(sat) | 2.0 V max @ IC = 4 A / IB = 16 mA - Limits conduction loss to ≤8 W at 4 A, improving thermal efficiency in linear and saturated-switching modes. |
| RθJC | 6.25 °C/W - Enables effective heat transfer to PCB copper pour or heatsink, supporting 20 W power dissipation at TC = 25 °C. |
| Package | DPAK (TO-252-3) - Surface-mount outline with exposed collector tab (pins 2 & 4) for low-inductance, high-current routing and thermal conduction. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control modules, body electronics, and ADAS power subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Darlington power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD122T4G | No NJV prefix; not AEC-Q101 qualified; identical electrical specs and DPAK package. | Intended for industrial/commercial use only; unsuitable for automotive production without additional qualification. | Select MJD122T4G for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
| BD679A | TO-126 package; lower IC = 4 A; VCEO = 80 V; no integrated base resistors; hFE = 750 min. | Requires external base bias network; limited to lower-voltage, lower-power applications with less stringent thermal demands. | Choose BD679A only when legacy TO-126 footprint is required and 80 V rating suffices. |
Compared with MJD122T4G and BD679A, NJVMJD122T4G-VF01 uniquely combines AEC-Q101 qualification, 100 V rating, 8 A capability, and integrated biasing in DPAK - making it the only drop-in solution for automotive-grade high-current Darlington switching where reliability and regulatory compliance are mandatory.

FAQ
What is the maximum continuous collector current rating for NJVMJD122T4G-VF01?
The NJVMJD122T4G-VF01 is rated for 8 A continuous collector current at TC = 25 °C. Derating applies above 25 °C at 0.16 W/°C for case-mounted operation. At TA = 25 °C (surface mount on minimum recommended pad), the rating drops to 1.75 A due to higher thermal resistance (RθJA = 71.4 °C/W). Always verify actual board-level thermal performance using measured junction temperature.
Does NJVMJD122T4G-VF01 require external base resistors?
No, NJVMJD122T4G-VF01 does not require external base resistors. It integrates monolithic base-emitter shunt resistors (≈8 kΩ and ≈120 Ω) as part of its Darlington structure. This design enables direct interface with microcontroller GPIOs and eliminates discrete bias components, simplifying circuit layout and improving reliability in high-vibration environments.
Is NJVMJD122T4G-VF01 suitable for automotive applications?
Yes, NJVMJD122T4G-VF01 is AEC-Q101 qualified and PPAP capable, making it suitable for automotive applications including engine control, body electronics, and ADAS subsystems. Its −65 °C to +150 °C operating junction temperature range, >8000 V HBM ESD rating, and Pb-free RoHS-compliant DPAK package meet stringent automotive manufacturing and field reliability requirements.
What is the collector-emitter saturation voltage of NJVMJD122T4G-VF01?
The NJVMJD122T4G-VF01 has a maximum VCE(sat) of 2.0 V at IC = 4 A and IB = 16 mA, and 4.0 V at IC = 8 A and IB = 80 mA. These values reflect guaranteed worst-case performance under specified test conditions and define conduction losses critical for thermal design in high-duty-cycle switching applications.
How does the DPAK package of NJVMJD122T4G-VF01 improve thermal performance?
The DPAK (TO-252-3) package of NJVMJD122T4G-VF01 features an exposed collector tab (Pins 2 and 4) that serves as both high-current path and primary thermal conduction route to the PCB copper pour or heatsink. With RθJC = 6.25 °C/W, it achieves significantly lower junction-to-case resistance than through-hole alternatives, enabling 20 W power dissipation at TC = 25 °C and supporting compact, fanless designs.
