Product details
Overview
DMTH47M2LFVW-7 from Diodes Incorporated is a 40V, +175°C-rated N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 8.9mΩ RDS(ON) at VGS = 10V and 49.0A continuous drain current at TC = +25°C. It features wettable flanks for optical inspection, 100% production-tested UIS robustness, and AEC-Q101 readiness for automotive power management.
For engineers reviewing the DMTH47M2LFVW-7 datasheet, DMTH47M2LFVW-7 pinout, DMTH47M2LFVW-7 application, or DMTH47M2LFVW-7 equivalent, key selection criteria include its low RDS(ON) × Qgd figure-of-merit, high-temperature operation up to +175°C, and PowerDI3333-8 thermal performance with 4°C/W RθJC.
Technical Context
This MOSFET uses planar silicon technology optimized for high-current, high-temperature switching in DC-DC converters and backlighting drivers. Its gate threshold voltage (1.2–2.3V) enables compatibility with 3.3V and 5V logic-level drive, while the 12.3nC total gate charge at VGS = 10V supports efficient high-frequency PWM control.
The device integrates a robust body diode with 31.9ns reverse recovery time and 25.0nC QRR, enabling reliable synchronous rectification and freewheeling in buck and boost topologies. Thermal design is supported by an exposed drain pad and 4°C/W junction-to-case resistance under soldered conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH47M2LPSQ-13 | Same die, PQFN-8 package with different leadframe plating (NiPdAu vs. matte tin); identical RDS(ON), Qg, and thermal specs | Designed for higher-reliability automotive PPAP programs; includes AEC-Q101 qualification report and IATF 16949 traceability | Select when full automotive change control, PPAP documentation, and certified manufacturing site are required |
| DMN3029LSD-13 | 30V VDSS, 2.9mΩ @ 10V, 60A ID - lower voltage rating but significantly lower RDS(ON) and higher current capability | Better suited for 12V-input systems where 40V headroom is excessive; not rated for +175°C operation (max TJ = +150°C) | Choose for cost-sensitive 12V applications needing ultra-low conduction loss, where ambient temperature stays below 105°C |
Compared with DMTH47M2LFVW-7, DMTH47M2LPSQ-13 adds automotive qualification rigor without electrical trade-offs, while DMN3029LSD-13 sacrifices voltage margin and high-temperature capability for lower RDS(ON) in milder thermal environments.

FAQ
What is the maximum continuous drain current at TC = +100°C?
The DMTH47M2LFVW-7 supports 34.7A continuous drain current at case temperature +100°C, per the Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerDI3333-8 package under real-world PCB mounting conditions with defined copper area and airflow.
Does this MOSFET require a gate resistor for safe operation?
A gate resistor is recommended to control dV/dt and suppress ringing during switching. The typical gate resistance is 2.06Ω (measured), and a 5–10Ω external series resistor is commonly used with 3.3V/5V gate drivers to limit peak current and ensure stable turn-on/turn-off behavior in high-frequency applications.
Is the body diode suitable for synchronous rectification?
Yes - the integrated body diode has a typical forward voltage of 0.9V at 20A and 31.9ns reverse recovery time, making it viable for synchronous rectification in buck converters up to ~500kHz. However, external Schottky diodes may be preferred for lowest-loss operation above 1MHz.
Can DMTH47M2LFVW-7 be used in place of a TO-252 DPAK MOSFET?
Yes, with PCB layout adaptation: the PowerDI3333-8 offers superior thermal resistance (RθJC = 4°C/W vs. ~6°C/W for DPAK) and higher current density, but requires revised footprint and stencil design. Its wettable flanks also enable AOI verification unavailable in standard DPAK packages.
