Product details

Overview

DMTH4014LFVWQ-13 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for 40 V V_DSS, 13.7 mΩ R_DS(ON) @ 10 V_GS, and 49.8 A I_D at T_C = +25°C. It operates up to +175°C junction temperature and supports automotive DC-DC converters, backlighting, and power-management functions.

For engineers reviewing the DMTH4014LFVWQ datasheet, DMTH4014LFVWQ pinout, DMTH4014LFVWQ application, or DMTH4014LFVWQ equivalent, this part delivers verified 100% UIS-tested ruggedness, wettable flank terminals for automated optical inspection, and low Q_gd × R_DS(ON) figure-of-merit for high-efficiency switching in thermally constrained automotive environments.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in 12 V/24 V automotive systems. Its ±20 V gate rating and 1–3 V gate threshold support robust drive with standard logic-level controllers and enable stable operation across -55°C to +175°C ambient ranges.

The device integrates a low-forward-voltage body diode (V_SD = 0.9–1.2 V @ 20 A) and exhibits 21 pF Crss, 225 pF Coss, and 11.2 nC total gate charge at 10 V_GS, enabling efficient synchronous rectification and high-frequency PWM control in buck and boost topologies.

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
STL135N4LF6AG	40 V, 1.35 mΩ R_DS(ON) @ 10 V_GS, PowerFLAT 5×6 package, higher current but larger footprint.	Targets higher-power ADAS ECUs where thermal mass allows larger package; lacks wettable flank.	Select when >50 A continuous current is required and board area permits larger outline.
ONsemi NTMFS4C10NT1G	40 V, 10.5 mΩ R_DS(ON) @ 10 V_GS, SO-8FL package, no AEC-Q101 qualification or PPAP support.	Suitable for industrial or consumer-grade DC-DC; not approved for automotive production programs.	Choose only for non-automotive prototypes or cost-sensitive non-safety applications.

Compared with STL135N4LF6AG and NTMFS4C10NT1G, DMTH4014LFVWQ uniquely combines AEC-Q101 compliance, wettable flank inspection capability, and 2.5 °C/W R_θJC in a 3.3 mm × 3.3 mm footprint-making it optimal for volume automotive designs requiring audit-ready traceability and compact thermal design.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The DMTH4014LFVWQ-13 supports 35.2 A continuous drain current at T_C = +100°C with V_GS = 10 V, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerDI3333-8 package and must be validated against actual PCB layout and heatsinking.

Does this MOSFET require a gate resistor for safe operation?

A gate resistor is recommended to control dV/dt and suppress ringing during switching. Typical values range from 1.6 Ω to 10 Ω depending on drive strength and layout parasitics; the datasheet specifies t_D(ON), t_R, t_D(OFF), and t_F using R_g = 1.6 Ω in test conditions.

Is the body diode suitable for synchronous rectification?

Yes-the body diode has a forward voltage of 0.9–1.2 V at 20 A and reverse recovery time of 11.3 ns, making it viable for synchronous rectification in medium-frequency DC-DC converters where external Schottky replacement is impractical.

How is moisture sensitivity classified for this package?

The PowerDI3333-8/SWP package carries J-STD-020 Moisture Sensitivity Level (MSL) 1, meaning it is not moisture-sensitive and may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow soldering.
