onsemi NJVMJD148T4G-VF01

Overview

NJVMJD148T4G-VF01 from onsemi is an NPN silicon power transistor in DPAK (TO-252) package, rated for 45 V_CEO, 4.0 A continuous collector current, and 20 W power dissipation at T_C = 25°C. It delivers high DC current gain (h_FE = 50–375), low V_CE(sat) (≤0.5 V at I_C = 2 A), and f_T = 3 MHz - optimized for general-purpose amplification and low-speed switching in automotive and industrial power control circuits.

For engineers reviewing the NJVMJD148T4G-VF01 datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, Pb-free RoHS-compliant DPAK-3 package, thermal resistance R_JC = 6.25°C/W, and validated performance across −55°C to +150°C junction temperature range.

Technical Context

This NPN bipolar junction transistor operates in linear amplification and saturated switching modes, with base-emitter turn-on voltage ≤1.1 V and collector-emitter sustaining voltage rated at 45 V under I_C = 100 mA, I_B = 0 conditions. Its gain-bandwidth product of 3 MHz supports audio-frequency and PWM-driven load control up to ~100 kHz.

The device uses a surface-mount DPAK-3 (Case 369C) thermally enhanced package with dual collector terminals (pins 2 and 4), enabling higher current handling and improved heat transfer to PCB copper. Thermal derating is defined at 0.16 W/°C above 25°C case temperature.

FAQ

What is the maximum continuous collector current rating for NJVMJD148T4G-VF01?

The NJVMJD148T4G-VF01 is rated for 4.0 A continuous collector current (I_C) at case temperature T_C = 25°C. Derating applies above this temperature at 0.16 W/°C for power dissipation, and actual current capability depends on PCB copper area, heatsinking, and ambient conditions. At T_C = 100°C, the usable I_C drops to approximately 2.8 A based on thermal limits.

Is NJVMJD148T4G-VF01 AEC-Q101 qualified and PPAP capable?

Yes, NJVMJD148T4G-VF01 carries the NJV prefix indicating it is manufactured under automotive-specific process controls and is fully AEC-Q101 qualified. It is also PPAP capable, meaning onsemi provides complete Production Part Approval Process documentation - including test reports, process flow diagrams, and control plans - required for Tier 1 automotive supply chain integration.

What package type and pin configuration does NJVMJD148T4G-VF01 use?

NJVMJD148T4G-VF01 uses the DPAK-3 (TO-252-3) surface-mount package (Case 369C), with pin 1 = Base, pins 2 and 4 = Collector (internally connected), and pin 3 = Emitter. The exposed collector tab serves as both electrical terminal and primary thermal path to the PCB, requiring soldering to a large copper pour for optimal thermal performance.

What is the typical DC current gain (h_FE) of NJVMJD148T4G-VF01 at 2 A collector current?

At I_C = 2 A and V_CE = 1 V, the NJVMJD148T4G-VF01 exhibits h_FE between 30 and 50, as specified in the Electrical Characteristics table. This range reflects production variation and must be accounted for in base drive design - e.g., using I_B ≥ 200 mA ensures saturation across all units at full load.

Can NJVMJD148T4G-VF01 replace MJD148T4G in existing designs?

Yes, NJVMJD148T4G-VF01 is functionally and electrically identical to MJD148T4G, sharing the same die, package, pinout, and specifications. The NJV prefix denotes additional automotive traceability and control - no layout or schematic changes are needed, though documentation updates may be required for PPAP compliance in automotive programs.
