Product details

Overview

DMTH4014LFVW-13 from Diodes Incorporated is a 40V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 49.8A continuous drain current at TC = +25°C and R_DS(ON) of 13.7mΩ @ V_GS = 10V. It features wettable flanks for automated optical inspection, 100% production-tested UIS robustness, and automotive-grade thermal reliability-used in high-efficiency DC-DC converters and LED backlighting power stages.

For engineers reviewing the DMTH4014LFVW-13 datasheet, DMTH4014LFVW-13 pinout, DMTH4014LFVW-13 application, or DMTH4014LFVW-13 equivalent, key selection criteria include R_DS(ON) at 4.5V (26mΩ), Q_gd × R_DS(ON) figure-of-merit, +175°C operation capability, and PowerDI3333-8 thermal performance with exposed drain pad.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in synchronous buck and load-switch topologies. Its gate threshold voltage (1–3V) enables compatibility with 3.3V and 5V logic-level drivers, while the 2.2nC Q_gd and 11.2nC total gate charge at V_GS = 10V support efficient high-frequency PWM control up to 1MHz.

Thermal design leverages the PowerDI3333-8's low R_θJC of 2.5°C/W to the exposed drain pad, enabling 57.7W power dissipation at T_C = +25°C. The device sustains 19.8A avalanche current (L = 0.1mH) and exhibits normalized R_DS(ON) drift of ≤1.8× across –55°C to +175°C junction range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage for 12V/24V input rail protection and point-of-load conversion
R_DS(ON) @ 10V	13.7mΩ - Enables <1.0W conduction loss at 20A, critical for thermally constrained PCB layouts
R_DS(ON) @ 4.5V	26mΩ - Ensures usable on-resistance with standard 5V gate drivers without level-shifting
I_D (T_C=25°C)	49.8A - Supports high-current single-phase buck stages without paralleling devices
Q_gd	2.2nC - Low Miller charge minimizes switching-induced shoot-through risk in synchronous rectification
T_J max	+175°C - Qualified for under-hood automotive, industrial motor drives, and sealed enclosure applications
E_AS	19.6mJ - Withstands repetitive inductive energy spikes in solenoid and relay drive circuits

Pinout & Package

Package: PowerDI®3333-8/SWP (Type UX), surface-mount, thermally enhanced with exposed drain pad on bottom side. Wettable flank terminals enable automated optical solder-joint inspection.

Pin/Terminal	Circuit Role	Design Meaning
D (Drain)	Main current path output / heat sink node	Exposed copper pad on bottom - must be connected to large PCB copper area for thermal management
G (Gate)	Control terminal for channel modulation	Low-input-capacitance node (C_iss = 750pF); requires <1.6Ω series resistor to damp ringing
S (Source)	Reference node for gate drive and current sensing	Three parallel source pins reduce parasitic inductance in high-di/dt switching paths

Key Features

Feature	Design Value
100% UIS tested	Guarantees robustness against inductive turn-off transients without derating in motor or solenoid drivers
Wettable flank leads	Enables AOI verification of solder fillet height on all four side terminals - eliminates X-ray inspection cost
+175°C rated operation	Validated over full temperature range; supports extended-life designs in engine control units and power tool ECUs
Halogen- & antimony-free	Meets JEDEC J-STD-020 MSL Level 1 and RoHS 3 (2015/863/EU) without compromising thermal cycling reliability
Low Q_gd × R_DS(ON)	Figure-of-merit of ~29.5 mΩ·nC - balances switching loss and conduction loss for 300–500kHz DC-DC operation

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-13	Automotive-grade variant (AEC-Q101 qualified); identical electrical specs and package	Required for automotive safety-critical systems (e.g., ADAS lighting, EPS); includes PPAP documentation	Select when ISO/TS 16949 compliance and zero-defect manufacturing traceability are mandatory
IPB120N04S4-02	40V, 120A, 2.0mΩ @ 10V in TO-263; higher current but larger footprint and no wettable flanks	Better for >60A applications where board space permits; lacks AOI-ready leads and MSL Level 1 rating	Choose only if peak current exceeds 50A and thermal interface to heatsink is available

Compared with DMTH4014LFVWQ-13, the base part lacks AEC-Q101 certification but offers identical performance and lower cost for industrial use; versus IPB120N04S4-02, it trades raw current capacity for superior manufacturability, thermal density, and inspection readiness in space-constrained designs.

FAQ

What is the maximum allowable gate-source voltage for DMTH4014LFVW-13?

The absolute maximum V_GS is ±20V per the datasheet. Operation beyond ±12V risks gate oxide degradation, especially at elevated temperatures. For reliable 4.5V logic-level drive, a 10V gate bias is recommended to ensure full enhancement while maintaining margin against transient overshoot.

Does DMTH4014LFVW-13 require a gate resistor, and what value is recommended?

Yes-a series gate resistor is required to control dV/dt and suppress oscillation. Based on measured R_g = 1.1Ω and typical layout inductance, a 1.6Ω resistor provides optimal trade-off between switching speed (t_r = 4.6ns) and EMI suppression, as validated in the datasheet's switching time test conditions.

Can DMTH4014LFVW-13 be used in linear (analog) regulation mode?

No-it is not characterized or guaranteed for linear-mode operation. The Safe Operating Area (SOA) curve shows only single-pulse capability down to DC; sustained linear operation risks thermal runaway due to positive R_DS(ON) temperature coefficient and lack of SOA derating data below 1ms.

How does the wettable flank feature impact reflow profile and solder inspection?

The wettable flank geometry ensures consistent solder meniscus formation on all four side terminals during standard lead-free reflow (peak 260°C). This enables reliable 2D AOI detection of solder joint height and voiding-eliminating need for costly 3D SPI or X-ray for process validation in high-volume manufacturing.
