Product details

Overview

DMTH4014LFVW-7 from Diodes Incorporated is a 40V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI3333-8 package, with R_DS(ON) = 13.7 mΩ @ V_GS = 10V, 49.8A continuous drain current at T_C = +25°C, and wettable flank terminals for automated optical inspection-designed for high-efficiency DC-DC converters in automotive and industrial power management.

For engineers reviewing the DMTH4014LFVW-7 datasheet, DMTH4014LFVW-7 pinout, DMTH4014LFVW-7 application, or DMTH4014LFVW-7 equivalent, key selection criteria include its 175°C junction rating, low Q_gd × R_DS(ON) figure-of-merit (FOM), 100% production-tested UIS robustness, and PowerDI3333-8 thermal performance with R_θJC = 2.5°C/W.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching, supporting high-frequency synchronous rectification in buck and boost topologies. Its gate threshold voltage (1–3 V) enables compatibility with 3.3V and 5V logic-level drive, while the 11.2 nC total gate charge at V_GS = 10V balances switching speed and drive loss.

The device integrates a robust body diode with t_RR = 11.3 ns and Q_RR = 9.5 nC under 400 A/μs di/dt, enabling efficient freewheeling in hard-switched converters. Thermal design is anchored to the exposed drain pad, delivering 57.7 W power dissipation at T_C = +25°C and stable R_DS(ON) up to 175°C junction temperature.

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
DMTH4014LFVWQ-7	Identical electrical specs but qualified to AEC-Q101 Grade 0 (−40°C to +175°C) with extended reliability testing (HTOL, UHAST, TC).	Required for automotive safety-critical functions (e.g., ADAS power stages); not needed for industrial or medical non-safety systems.	Select when automotive qualification and PPAP documentation are mandatory-same footprint and thermal behavior.
IPB180N04S4-02	40V, 180A, 2.0 mΩ R_DS(ON), TO-263-7 package; higher current, lower R_DS(ON), but larger footprint and 3× gate charge (33 nC).	Suitable for higher-power (>60 A) applications where board space allows TO-263 and thermal mass supports higher P_D.	Choose only if system requires >50 A continuous current and can accommodate larger thermal solution-no pin compatibility.

Compared with DMTH4014LFVW-7, the DMTH4014LFVWQ-7 adds automotive qualification without altering electrical or thermal performance, while the IPB180N04S4-02 trades compactness and gate-drive efficiency for raw current capacity-making the DMTH4014LFVW-7 optimal for space-constrained, high-frequency 30–50 A designs.

FAQ

What is the maximum safe operating frequency for DMTH4014LFVW-7 in a hard-switched buck converter?

Based on its 11.2 nC total gate charge and 21 pF reverse transfer capacitance, the DMTH4014LFVW-7 supports reliable hard-switched operation up to 1.2 MHz with proper gate drive (≤2 Ω resistance) and layout (minimized loop inductance). Above this, switching losses increase nonlinearly due to C_rss Miller effect-verified via measured t_D(ON) = 3.5 ns and t_F = 4.9 ns at 20 V drive.

Does DMTH4014LFVW-7 require a negative gate voltage for reliable turn-off in high-noise environments?

No. The device's gate threshold voltage (1–3 V) and ±20 V gate-source rating allow robust turn-off with 0 V gate drive. A negative voltage is unnecessary; however, a −2 V to −5 V turn-off bias may reduce dv/dt-induced false triggering in >100 V/ns noise environments-validated by its 100% UIS test margin and low Crss (21 pF).

Can DMTH4014LFVW-7 replace SiC MOSFETs in 400 kHz PFC circuits?

No. While it excels in DC-DC conversion, its 750 pF input capacitance and 12.4 ns turn-off delay limit efficiency above 200 kHz in PFC applications. SiC devices offer superior C_iss/C_oss ratios and faster recovery-this part is optimized for buck/boost topologies, not high-voltage, high-frequency PFC where SiC's advantages dominate.

Is the PowerDI3333-8/SWP package compatible with standard reflow profiles for lead-free assembly?

Yes. The package meets J-STD-020 Level 1 moisture sensitivity and is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C for ≤60 seconds. Its matte tin annealed finish ensures reliable solderability per MIL-STD-202, Method 208, with no pre-bake required for typical production runs.
