Product details
Overview
DMN6040SFDEQ-13 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET qualified to AEC-Q101, with RDS(ON) = 38 mΩ @ VGS = 10 V, ID = 6.5 A at TA = +25°C, and housed in a U-DFN2020-6 (Type E) package. It serves as a high-reliability power switch in automotive DC-DC converters and backlighting circuits.
For engineers reviewing the DMN6040SFDEQ-13 datasheet, DMN6040SFDEQ-13 pinout, DMN6040SFDEQ-13 application, or DMN6040SFDEQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 0.6 mm height, 4 mm² PCB footprint, 100% production-tested UIS capability, and dual gate-drive compatibility (4.5 V and 10 V).
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in automotive-grade power stages. Its thermal design supports 61 °C/W RθJA under enhanced pad layout, enabling sustained 2.03 W power dissipation at +25°C ambient.
The device integrates a robust body diode with tRR = 18 ns and QRR = 11.9 nC, supporting synchronous rectification and flyback recovery in compact DC-DC topologies. Gate charge parameters (Qg = 22.4 nC @ 10 V, Qgd = 3.0 nC) are tuned for efficient drive with standard gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Withstands up to 60 V drain-source blocking voltage in automotive 42 V systems. |
| RDS(ON) | 38 mΩ @ VGS = 10 V - Enables <1.5 W conduction loss at 6.5 A continuous current. |
| ID (max) | 6.5 A @ TA = +25°C - Supports high-current load switching in space-constrained modules. |
| Qg | 22.4 nC @ VGS = 10 V - Matches common gate drivers (e.g., TI UCC2753x) without excessive drive power. |
| tRR | 18 ns - Minimizes reverse recovery loss during hard-switched operation in buck converters. |
| RθJA | 61 °C/W - Achievable with 1-inch² copper pour; enables thermal management in sealed automotive enclosures. |
| Package | U-DFN2020-6 (Type E) - 2.0 × 2.0 × 0.6 mm footprint ideal for ultra-thin LED driver PCBs. |
Pinout & Package
U-DFN2020-6 (Type E) is a 6-terminal, bottom-exposed thermal pad package with 0.65 mm pitch and NiPdAu-plated terminals. The exposed pad improves thermal transfer to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Common source connection for low-side switching; tied to thermal pad for enhanced heat sinking. |
| 4 | Gate | Control input requiring ≤±20 V rating; low Ciss (1287 pF) reduces driver loading. |
| 5, 6 | Drain | High-side power node; dual-drain configuration lowers parasitic inductance in high-frequency switching. |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested | Guarantees ruggedness against inductive kickback in motor drivers and solenoid controls without external snubbers. |
| 0.6 mm profile | Enables integration into sub-1 mm total board height assemblies such as automotive instrument cluster backlights. |
| AEC-Q101 qualified | Validated for automotive temperature range (−55°C to +150°C) and PPAP-ready for Tier-1 production release. |
| Halogen/antimony-free | Meets automotive OEM green material requirements (<900 ppm Br/Cl, <1000 ppm Sb) without compromising reliability. |

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 |
|---|---|---|---|
| DMN6040SFDEQ-7 | Same die and package; differs only in tape-and-reel quantity (3,000 pcs vs. 10,000 pcs). | No functional difference; used for smaller-batch prototyping or JIT assembly lines. | Select -7 for engineering validation; -13 for volume production with extended reel life. |
| DMN6040SFH-7 | Same electrical specs but in U-DFN2020-6 (Type H) - identical outline but different marking and traceability scheme. | Approved for same AEC-Q101 applications; Type H adds enhanced moisture sensitivity level (MSL) tracking per J-STD-020. | Choose -7 if MSL Level 1 compliance verification is required beyond standard qualification. |
Compared with DMN6040SFDEQ-13, the -7 variant offers identical performance in smaller reels for flexibility, while the SFH-7 variant provides tighter process traceability for high-audit automotive programs-neither alters thermal, electrical, or mechanical behavior in circuit design.

FAQ
What is the maximum continuous drain current at 100°C ambient?
At TA = +100°C, the DMN6040SFDEQ-13 supports 3.2 A continuous drain current (ID) when mounted on FR-4 with 1-inch² copper pour, based on its RθJA = 61 °C/W and PD derating curve. This value assumes no additional airflow or heatsinking.
Does this MOSFET require a gate resistor for automotive 12 V systems?
A gate resistor is recommended between driver output and pin 4 (Gate) to dampen ringing caused by PCB trace inductance and gate capacitance (Ciss = 1287 pF). Typical values range from 5 Ω to 22 Ω depending on switching frequency and EMI targets-no internal gate resistor is present.
Is the thermal pad electrically isolated?
No-the exposed thermal pad (pins 1–3 and underside metal) is internally connected to Source. It must be soldered to a PCB ground plane or source-coupled copper area to ensure both thermal performance and correct circuit reference.
Can this MOSFET replace older TO-252 devices in existing designs?
Direct replacement is not possible due to package incompatibility: U-DFN2020-6 (2.0 × 2.0 mm) has no leaded pins and requires re-layout for solder paste stencil, pad geometry, and thermal relief. Electrical equivalence exists, but mechanical redesign is mandatory.
