Product details
Overview
NJVMJD44H11T4G-VF01 from onsemi is an NPN silicon power transistor in DPAK (TO-252) 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, targeting output/driver stages in switching regulators, DC-DC converters, and linear power amplifiers.
For engineers reviewing the NJVMJD44H11T4G-VF01 datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, complementary pairing with MJD45H11, thermal resistance RJC = 6.25 °C/W, and Pb-free RoHS-compliant DPAK-3 package with dual collector terminals.
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, and fT = 85 MHz under IC = 0.5 A/VCE = 10 V conditions. Its safe operating area (SOA) is defined up to 150 °C junction temperature, constrained by both thermal limits and second breakdown.
The device features electrically similar characteristics to legacy D44H series transistors but adds automotive-grade traceability via NJV prefix, UL 94 V-0 epoxy, and PPAP capability. Its dual-collector DPAK-3 configuration (pins 2 and 4) enables enhanced current handling and thermal path optimization in PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum blocking voltage before avalanche in common-emitter configuration; defines upper rail limit in switch-mode topologies. |
| IC (cont.) | 8 A - Continuous collector current rating at TC = 25 °C; requires heatsinking above ambient to sustain full load. |
| VCE(sat) | ≤1 V @ IC = 8 A, IB = 0.4 A - Low saturation voltage minimizes conduction loss and heat generation in high-current switching. |
| fT | 85 MHz - Current-gain bandwidth product; supports stable operation in audio and medium-frequency SMPS feedback loops. |
| RJC | 6.25 °C/W - Junction-to-case thermal resistance; enables direct mounting to heatsinks for efficient power dissipation. |
| hFE | ≥60 @ IC = 2 A, VCE = 1 V - Sufficient DC gain for base-driven applications without excessive drive current overhead. |
| td + tr | ≤300 ns @ IC = 5 A, IB1 = 0.5 A - Fast turn-on delay and rise time reduces switching losses in PWM-based power stages. |

FAQ
What is the maximum junction temperature rating for NJVMJD44H11T4G-VF01?
The NJVMJD44H11T4G-VF01 has an operating junction temperature range of −55 °C to +150 °C, as specified in the Absolute Maximum Ratings table. This allows reliable operation in under-hood automotive environments and high-temperature industrial enclosures when thermal design adheres to RJC = 6.25 °C/W and recommended PCB pad layout.
Does NJVMJD44H11T4G-VF01 support direct replacement for legacy D44H11 devices?
Yes, NJVMJD44H11T4G-VF01 is electrically similar to the D44H11 series and shares identical pinout, voltage/current ratings, and switching characteristics. However, it adds AEC-Q101 qualification, NJV prefix traceability, and Pb-free RoHS compliance-making it a drop-in upgrade for new designs requiring automotive-grade assurance.
What is the purpose of the dual collector terminals (pins 2 and 4) on NJVMJD44H11T4G-VF01?
The dual collector terminals on NJVMJD44H11T4G-VF01 provide redundant current paths and improved thermal conduction to the PCB. Pin 2 and pin 4 are internally connected, allowing designers to route separate low-inductance traces or connect both to a large copper pour-enhancing reliability in high-di/dt applications like motor drives and SMPS.
Is NJVMJD44H11T4G-VF01 compatible with lead-free reflow soldering processes?
Yes, NJVMJD44H11T4G-VF01 is Pb-free and RoHS compliant, with a maximum lead temperature rating of 260 °C for 10 seconds. It is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260 °C and ramp rates within specification limits.
How does the thermal resistance RJA = 71.4 °C/W affect PCB layout for NJVMJD44H11T4G-VF01?
The RJA = 71.4 °C/W value applies only when mounted on minimum recommended pad sizes; actual thermal performance depends heavily on PCB copper area and layer stack-up. To approach the 20 W power rating, designers must use ≥2 oz copper, thermal vias under the exposed pad, and avoid narrow traces-otherwise junction temperature will exceed 150 °C even at moderate loads.
