Product details

Overview

DMTH4014LFVWQ-7 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 backlighting, DC-DC converters, and power-management functions.

For engineers reviewing the DMTH4014LFVWQ-7 datasheet, DMTH4014LFVWQ-7 pinout, DMTH4014LFVWQ-7 application, or DMTH4014LFVWQ-7 equivalent, key selection criteria include its wettable flank package for optical inspection, 100% production-tested UIS robustness, low Q_gd × R_DS(ON) figure-of-merit, and IATF 16949-certified manufacturing.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for high-temperature automotive operation. Its gate threshold voltage (1–3 V) enables compatibility with 3.3 V and 5 V logic-level drivers, while the 2.5 °C/W R_θJC thermal resistance supports high-power density mounting on exposed drain pads.

The device integrates a robust body diode with 11.3 ns reverse-recovery time and 9.5 nC Q_RR at 15 A/400 A/μs, enabling efficient synchronous rectification and freewheeling in buck and boost topologies. Its 750 pF C_iss and 21 pF Cr_ss support fast switching with controlled EMI in 200–500 kHz DC-DC stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Withstands peak drain-source transients in 12 V and 24 V automotive systems without avalanche breakdown.
R_DS(ON) @ 10 V_GS	13.7 mΩ max - Limits conduction loss to ≤13.7 W at 100 A in parallel configurations with proper thermal management.
I_D @ T_C = 25°C	49.8 A - Supports high-current power rails in engine control units and ADAS domain controllers with heatsink attachment.
T_J Operating Range	−55°C to +175°C - Enables placement near heat sources (e.g., powertrain modules) without derating in under-hood environments.
Q_g @ 10 V_GS	11.2 nC - Determines gate drive power requirement (~112 μJ per switch cycle at 10 V), critical for selecting driver IC output current.
E_AS	19.6 mJ - Specifies single-pulse avalanche energy handling capability, essential for inductive load switching reliability.
Wettable Flank	Yes - Enables automated optical inspection (AOI) of solder joints on bottom-side terminals, improving SMT yield in automotive PCB assembly.

Pinout & Package

Package: PowerDI3333-8/SWP (Type UX), surface-mount, thermally enhanced with exposed drain pad. Molded green compound, UL 94V-0 rated, 0.029 g mass.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (D)	Drain	Main high-current path; electrically and thermally connected to exposed copper pad - must be soldered to large PCB copper area for thermal dissipation.
Pins 2, 3, 4, 5 (S)	Source	Common source connection for all internal cells; used for current return and gate drive reference; multiple pins reduce parasitic inductance.
Pins 6, 7, 8 (G)	Gate	Control input; three parallel terminals minimize gate loop inductance and improve switching stability in high-dI/dt applications.

Key Features

Feature	Design Value
AEC-Q101 qualification & PPAP support	Validated for automotive production use with full change control, traceable lot documentation, and IATF 16949 manufacturing.
175°C maximum junction temperature	Enables operation in under-hood locations (e.g., battery disconnect units) without thermal throttling or forced cooling.
Low Q_gd × R_DS(ON) FOM	22.2 mΩ·nC - Balances switching speed and conduction loss, reducing total power loss in hard-switched 200–300 kHz converters.
100% production UIS testing	Each unit passes unclamped inductive switching stress test (L = 0.1 mH, I_AS = 19.8 A), ensuring field reliability in motor drive and solenoid loads.
Matte tin annealed terminals	Ensures consistent solderability per MIL-STD-202 Method 208, eliminating intermetallic growth issues in lead-free reflow profiles.

Applications

Automotive LED Backlighting

Use Scenario: Driving high-brightness LED strings in instrument clusters and center displays with PWM dimming.

IC Role / Device Role / Timing Role: High-side switch controlling LED current path; switched at 1–20 kHz for brightness regulation.

Use Value: Low R_DS(ON) minimizes heat generation in confined display bezels; 175°C rating avoids thermal shutdown during prolonged sunload exposure.

Use Scenario: Primary switch in 12 V input, 3.3 V/5 V output synchronous buck converter for infotainment SoCs.

IC Role / Device Role / Timing Role: Main power switch operating at 300–500 kHz; paired with low-V_F Schottky sync rectifier.

Use Value: 11.2 nC Q_g enables efficient gate driving with low-power controllers; wettable flank ensures AOI detection of solder voids affecting thermal performance.

Engine Control Unit Power Management

Electric Power Steering (EPS) Motor Driver Stage

Use Scenario: Load switching for fuel injector drivers and sensor bias supplies in ECU mainboard power distribution.

IC Role / Device Role / Timing Role: High-reliability power switch activated by microcontroller GPIO; subjected to load dump and cold crank transients.

Use Value: 40 V V_DSS withstands ISO 7637-2 Pulse 5a (load dump up to 35 V); 100% UIS testing prevents failure during inductive flyback events.

Use Scenario: Half-bridge high-side switch in 3-phase EPS motor gate driver stage, controlling 12–48 V motor phases.

IC Role / Device Role / Timing Role: Fast-switching power transistor with <15 ns turn-off delay; operated with bootstrap gate drive and shoot-through protection.

Use Value: 21 pF Cr_ss reduces Miller-induced false turn-on risk; 2.5 °C/W R_θJC allows direct thermal coupling to aluminum heatsink in compact EPS module housing.

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
STL220N4F7AG	40 V, 2.2 mΩ R_DS(ON) @ 10 V_GS, PowerFLAT 5x6 package, no wettable flank.	Lower R_DS(ON) but higher gate charge (34 nC); requires larger gate driver; lacks AOI-compatible terminals.	Select when ultra-low conduction loss dominates over optical inspection requirements and board space permits larger footprint.
IXTQ36N40P	400 V, 0.12 Ω R_DS(ON), TO-220AB package, −55°C to +175°C, no AEC-Q101 qualification.	Higher voltage rating but 9× higher R_DS(ON); through-hole mounting; not PPAP-capable or automotive qualified.	Select only for non-automotive industrial 40 V applications where qualification and SMT are not required.

Compared with STL220N4F7AG and IXTQ36N40P, DMTH4014LFVWQ-7 uniquely balances automotive qualification, wettable flank AOI support, and mid-range R_DS(ON)/Q_g trade-off - making it optimal for cost-sensitive, safety-critical SMT power stages requiring production traceability and thermal resilience.

FAQ

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

The DMTH4014LFVWQ-7 supports 35.2 A continuous drain current at T_C = +100°C with V_GS = 10 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerDI3333-8 package's 2.5 °C/W R_θJC and PCB copper layout constraints.

Does this MOSFET require a gate resistor for automotive PWM applications?

Yes - a 1.6 Ω gate resistor is used in the datasheet's switching time test conditions (t_D(ON), t_R). For 300–500 kHz automotive DC-DC operation, a 2.2–4.7 Ω resistor balances EMI suppression and switching loss; lower values increase dI/dt stress on gate drivers.

Is the body diode suitable for synchronous rectification in buck converters?

Yes - the body diode has 11.3 ns reverse-recovery time and 9.5 nC Q_RR at 15 A/400 A/μs, enabling efficient freewheeling in medium-frequency buck stages. However, external Schottky diodes or dedicated sync-FETs are preferred for >1 MHz operation due to lower Q_RR.

How does the wettable flank feature impact PCB assembly yield?

The wettable flank enables side-view AOI detection of solder fillet height and bridging on the exposed drain and source terminals. In automotive SMT lines, this reduces escape of insufficient-solder defects by >95% compared to standard PowerDI packages without flank plating.
