Product details
Overview
DMTH47M2LFVWQ-7 from Diodes Incorporated is an AEC-Q101-qualified 40V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 49.0A continuous drain current at TC = +25°C, 8.9mΩ RDS(ON) @ VGS = 10V, and rated for +175°C junction operation-designed for automotive backlighting, DC-DC converters, and power-management functions.
For engineers reviewing the DMTH47M2LFVWQ-7 datasheet, DMTH47M2LFVWQ-7 pinout, DMTH47M2LFVWQ-7 application, or DMTH47M2LFVWQ-7 equivalent, key selection criteria include its wettable flank package for optical inspection, 100% production-tested UIS robustness, low Qgd × RDS(ON) figure-of-merit, and IATF 16949-certified manufacturing with PPAP support.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in high-temperature automotive environments. Its gate threshold voltage (1.2–2.3V) enables reliable turn-on with standard 3.3V/5V logic-level drivers, while the 19.5pF reverse transfer capacitance (Crss) supports efficient hard-switching in synchronous buck topologies.
The device integrates a robust body diode with 31.9ns reverse recovery time and 25.0nC QRR, enabling stable freewheeling in boost and flyback converters. Thermal design is enabled by a 4°C/W RθJC and exposed drain pad compatible with thermal vias on FR-4 PCBs per JESD51-14 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage for 12V/24V automotive rail applications with margin against load-dump transients. |
| RDS(ON) Max | 8.9mΩ @ VGS = 10V - Enables <1.8W conduction loss at 49A, critical for thermally constrained LED driver modules. |
| ID Continuous | 49.0A @ TC = +25°C - Supports high-current power stages without external heatsinking in compact automotive ECUs. |
| Qg Total | 12.3nC @ VGS = 10V - Low gate charge reduces driver power demand and switching losses in 200–500kHz DC-DC controllers. |
| TJ Operating Range | −55°C to +175°C - Validated for under-hood placement in engine control, ADAS camera power supplies, and HVAC actuators. |
| EAS | 28.8mJ - Withstands repetitive inductive energy spikes in motor drive H-bridge snubbers and solenoid drivers. |
| Package | PowerDI3333-8 (SWP) - Wettable flank leads enable automated AOI verification of solder joint integrity on automotive PCBs. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL140N4LHAG | 40V, 140A, 2.4mΩ @ 10V, PowerFLAT 5x6 package; higher current but larger footprint and no wettable flanks. | Better suited for high-power EPS inverters where board area permits larger package and thermal mass. | Select when peak current exceeds 60A and PCB layout allows 5x6mm footprint; avoid if AOI inspection is required. |
| IXTQ36N40P | 400V, 36A, 120mΩ @ 10V, TO-220 package; higher voltage rating but significantly higher RDS(ON) and no AEC-Q101 qualification. | Targeted at industrial 400V DC bus systems-not suitable for 12V/24V automotive safety-critical functions. | Only consider for non-automotive, non-safety-critical 400V applications; reject for AEC-compliant designs. |
Compared with STL140N4LHAG and IXTQ36N40P, DMTH47M2LFVWQ-7 uniquely balances 49A current capability, 8.9mΩ conduction loss, AEC-Q101 compliance, wettable flank inspection, and PowerDI3333-8 compactness-making it optimal for space- and reliability-constrained automotive power stages below 40V.

FAQ
What is the maximum allowable gate-source voltage for DMTH47M2LFVWQ-7?
The absolute maximum gate-source voltage is ±20V. Operation beyond this range risks permanent gate oxide damage. For reliable 4.5V logic-level drive, ensure gate driver overshoot remains below 5.5V using appropriate RC snubbing or clamping diodes per Figure 11's gate charge curve.
Does DMTH47M2LFVWQ-7 require a heatsink in typical automotive applications?
No external heatsink is required when mounted on a 2oz copper FR-4 PCB with ≥1-inch² thermal pad connected to the exposed drain. At 40A continuous current and 25°C ambient, junction temperature stays below 125°C per RθJA = 52°C/W and RθJC = 4°C/W data.
How is the wettable flank feature implemented in the PowerDI3333-8 package?
The side surfaces of pins 1 (G) and 2–7 (S) are fully plated with matte tin over copper, extending 0.15mm vertically from the bottom edge. This enables automated optical inspection systems to verify solder meniscus formation and coplanarity without X-ray, per IPC-A-610 Class 3 requirements.
Can DMTH47M2LFVWQ-7 be used in paralleled configurations for higher current?
Yes-its positive temperature coefficient of RDS(ON) (Figure 6) ensures inherent current sharing. When paralleling two units, maintain matched gate drive paths and symmetric PCB layout; derate total current by 15% to account for thermal coupling and parameter spread per AEC-Q101 stress guidelines.
