Product details
Overview
DMTH4007SK3-13 from Diodes Incorporated is a 40V, 80A N-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for continuous operation up to +175°C junction temperature, with 6mΩ RDS(ON) at VGS = 10V and 20A, optimized for high-efficiency DC-DC converters and automotive-grade power management systems.
For engineers reviewing the DMTH4007SK3-13 datasheet, DMTH4007SK3-13 pinout, DMTH4007SK3-13 application, or DMTH4007SK3-13 equivalent, key selection criteria include its AEC-Q101 qualification, 100% unclamped inductive switching rating, low Qgd × RDS(ON) figure-of-merit, thermal robustness at +175°C, and TO252 package suitability for high-current PCB layouts with exposed drain pad.
Technical Context
This MOSFET employs planar silicon technology with optimized gate oxide and channel doping to achieve ultra-low on-resistance while maintaining fast switching transitions and robust avalanche capability. Its 2.5°C/W RθJC enables high-power dissipation when mounted to heatsinked copper planes.
The device integrates a body diode with 1.2V forward voltage at 20A and 29.9ns reverse recovery time, supporting synchronous rectification and freewheeling in buck and half-bridge topologies. Gate charge parameters (Qg = 41.9nC, Qgd = 11.5nC) are tuned for efficient drive with standard gate drivers at 10V logic levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage before avalanche onset; sets upper limit for input voltage in buck converters. |
| RDS(ON) | 6mΩ @ VGS = 10V, ID = 20A - Enables <1.2W conduction loss at 20A, critical for thermal management in compact power stages. |
| ID (TC = 25°C) | 76A - Continuous drain current rating under ideal heatsinking; defines maximum safe steady-state load current. |
| EAS | 60mJ - Avalanche energy rating at L = 0.3mH; ensures reliable operation during inductive turn-off transients without failure. |
| TJ Range | –55°C to +175°C - Extended junction temperature range supports under-hood automotive and industrial environments without derating. |
| Qgd × RDS(ON) | 69 mΩ·nC - Low figure-of-merit reduces switching losses and improves efficiency in high-frequency (>500kHz) power supplies. |
| RθJC | 2.5°C/W - Thermal resistance from junction to case; enables precise thermal modeling when soldered to copper thermal pads. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL130N4LF6AG | 40V, 130A, RDS(ON) = 3.2mΩ @ 10V, PowerFLAT 5x6 package, lower RDS(ON) but higher Qg (65nC) | Better conduction loss at >30A; less suitable for space-constrained layouts due to larger footprint | Select when peak efficiency >98% is required and board area permits larger package. |

FAQ
Is DMTH4007SK3-13 suitable for synchronous rectification in a 400kHz buck converter?
Yes. With Qgd = 11.5nC, RDS(ON) = 6mΩ, and tr/tf = 11.5ns/8.8ns, it supports efficient synchronous rectification up to 1MHz. Its low Crss minimizes Miller-induced cross-conduction, and the 100% UIS rating ensures resilience against transient overvoltage during dead-time transitions.
What is the recommended PCB layout for thermal performance?
Use a minimum 25mm² exposed copper pad (2oz copper) connected to internal ground/power planes via ≥6 thermal vias (0.3mm diameter, 0.8mm pitch). The drain pad must be the sole thermal path; avoid solder mask over the pad. Follow Diodes' suggested TO252 pad layout (C = 4.572mm × 1.060mm) for optimal solder joint reliability and thermal transfer.
Does DMTH4007SK3-13 require gate resistors for driving with an ISOS6741 isolated driver?
Yes. A 5–10Ω series gate resistor is recommended to dampen ringing and control dV/dt during switching. This prevents false triggering and reduces EMI. The gate threshold voltage (2–4V) and 0.46Ω intrinsic Rg make external damping essential when using fast isolated drivers with high peak current capability.
Can this MOSFET replace SiC devices in 40V applications?
No. While DMTH4007SK3-13 excels in silicon-based 40V systems, it lacks the ultra-fast switching, near-zero reverse recovery, and high-temperature capability of SiC MOSFETs. It is not a drop-in replacement for SiC in >200kHz, high-efficiency PFC or resonant topologies where SiC's advantages dominate.
