Product details

Overview

DMNH4006SK3Q-13 from Diodes Incorporated is an AEC-Q101-qualified 40V N-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for 140A continuous drain current at TC = +25°C, 6mΩ R_DS(ON) @ V_GS = 10V, and operation up to +175°C junction temperature-designed for high-reliability automotive power switching in engine control units and DC-DC converters.

For engineers reviewing the DMNH4006SK3Q-13 datasheet, DMNH4006SK3Q-13 pinout, DMNH4006SK3Q-13 application, or DMNH4006SK3Q-13 equivalent, key selection criteria include its 100% unclamped inductive switching rating, low 51nC total gate charge at V_GS = 10V, 0.8°C/W junction-to-case thermal resistance, and PPAP-capable manufacturing in IATF 16949-certified facilities.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction and switching losses in high-current automotive power stages. Its 6mΩ R_DS(ON) enables efficient 140A operation at TC = +25°C, while the 175°C maximum junction temperature supports under-hood deployment without derating in thermally constrained environments.

The device integrates a robust body diode with 32ns reverse recovery time and 28nC Q_RR, supporting synchronous rectification and freewheeling in buck/boost topologies. Its 2280pF input capacitance and 282pF reverse transfer capacitance are characterized at V_DS = 25V, enabling precise gate drive design for fast turn-on (7.7ns delay) and controlled turn-off (18ns delay).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage before avalanche; sets system-level bus voltage limit in 12V/24V automotive architectures.
R_DS(ON)	6mΩ @ V_GS = 10V - Enables <1W conduction loss at 140A; critical for thermal management in compact power modules.
I_D (continuous, TC=25°C)	140A - Supports high-current motor drivers and starter solenoid interfaces without external heatsinking beyond PCB copper.
Q_g (V_GS=10V)	51nC - Determines gate driver current requirement (~5.1A peak for 10ns rise time); impacts switching efficiency in 100–500kHz DC-DC converters.
R_θJC	0.8°C/W - Allows direct thermal coupling to heatsink via exposed drain pad; enables accurate junction temperature prediction in safety-critical systems.
t_RR	32ns - Limits reverse recovery energy loss during hard-switched transitions; reduces EMI and stress on complementary switches.
T_J max	+175°C - Permits operation in engine bay locations where ambient exceeds +125°C; eliminates need for active cooling in many applications.

Pinout & Package

Package: TO252 (DPAK), surface-mount, with exposed drain pad for thermal and electrical connection. Molded green compound, UL 94V-0 rated, matte tin annealed finish over copper leadframe.

Pin 3 (Drain)	High-side power output terminal	Connected to load or bus rail; electrically and thermally tied to large copper area on PCB for heat dissipation.

Key Features

Feature	Design Value
AEC-Q101 qualification & PPAP support	Validated for automotive production use with full change control, traceable lot data, and IATF 16949 manufacturing.
100% unclamped inductive switching (UIS)	Rated for 64A avalanche current and 208mJ single-pulse energy-ensures survival during inductive load transients without snubbers.
Low R_DS(ON) and Q_g	6mΩ on-resistance and 51nC gate charge jointly minimize both conduction and switching losses in high-frequency power stages.
175°C maximum junction temperature	Enables reliable operation in under-hood environments where ambient reaches +125°C, reducing thermal derating overhead.
Halogen- and antimony-free "Green" construction	Meets RoHS 3 (2015/863/EU) with <900ppm Br, <900ppm Cl, <1000ppm Sb-compliant for global automotive supply chain requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4L5F7	40V, 220A, 3.5mΩ @ 10V, TO263-7 package; higher current but larger footprint and no AEC-Q101 documentation shown publicly.	Requires larger PCB area and different thermal interface; suitable only where space permits and AEC-Q101 compliance is verified per lot.	Select only if 220A rating is mandatory and board layout accommodates TO263-7; verify PPAP status directly with STMicroelectronics.
IXTP150N045T	45V, 150A, 4.5mΩ @ 10V, TO220 package; lacks AEC-Q101 qualification and automotive-specific reliability testing.	Not approved for safety-critical automotive functions; limited to industrial or aftermarket designs without OEM validation requirements.	Use only in non-automotive contexts; avoid where PPAP, IATF 16949 sourcing, or 175°C operation are required.

Compared with STL220N4L5F7 and IXTP150N045T, the DMNH4006SK3Q-13 uniquely combines AEC-Q101 qualification, TO252 thermal efficiency, and documented PPAP readiness-making it the only choice for volume automotive production where footprint, qualification, and thermal performance must all be simultaneously met.

FAQ

What is the maximum allowable gate-source voltage for DMNH4006SK3Q-13?

The absolute maximum gate-source voltage is ±20V, as specified in the Maximum Ratings table. Exceeding this value risks permanent gate oxide damage. For reliable operation, gate drive circuits should clamp V_GS between –10V (for fast turn-off) and +12V (to ensure full enhancement without overstress), with transient spikes suppressed using Zener clamps or dedicated gate drivers with built-in protection.

Does DMNH4006SK3Q-13 require a heatsink when operating at 140A continuous current?

No external heatsink is required if mounted on a PCB with ≥1 inch² of 2oz copper connected to the exposed drain pad, as validated in the datasheet's thermal test condition (Note 6). The 0.8°C/W R_θJC enables direct thermal transfer to the board; however, airflow or ambient >85°C may necessitate additional copper area or localized forced convection to maintain T_J ≤ 175°C.

How does the body diode performance impact synchronous rectification in DC-DC converters?

The body diode exhibits 32ns reverse recovery time and 28nC Q_RR at 50A/100A/μs, enabling efficient synchronous rectification up to ~300kHz. Its low V_SD (0.7V typ at 1A) reduces forward conduction loss, while fast recovery minimizes shoot-through risk and associated EMI-critical for maintaining high efficiency (>95%) in 48V–12V automotive buck converters.

Is DMNH4006SK3Q-13 compatible with lead-free reflow soldering processes?

Yes-it features matte tin annealed over copper leadframe and is qualified for lead-free reflow per JEDEC J-STD-020, with Moisture Sensitivity Level 1 (unlimited floor life at <30°C/60% RH). Peak reflow temperature of 260°C is supported, and the green molding compound meets UL 94V-0 flammability requirements for automotive PCB assembly.
