Product details
Overview
DMTH4007LK3Q-13 from Diodes Incorporated is a 40V, 70A N-channel enhancement-mode MOSFET in TO252 (DPAK) package, qualified to AEC-Q101 and rated for continuous operation at +175°C. It delivers 7.3mΩ RDS(ON) at VGS = 10V and 9.8mΩ at VGS = 4.5V, with 160A pulsed drain current capability-designed for high-efficiency DC-DC converters in engine-management systems.
For engineers reviewing the DMTH4007LK3Q-13 datasheet, DMTH4007LK3Q-13 pinout, DMTH4007LK3Q-13 application, or DMTH4007LK3Q-13 equivalent, key selection criteria include its AEC-Q101 qualification, low RDS(ON) at 4.5V gate drive, thermal robustness up to +175°C junction temperature, and TO252 package suitability for automotive PCB layouts with exposed drain pad thermal management.
Technical Context
This MOSFET employs planar trench-gate technology optimized for fast switching and low conduction loss in 12V/24V automotive power rails. Its gate threshold voltage (1–3V) ensures reliable turn-on with standard microcontroller GPIOs, while low input capacitance (1895pF) and gate charge (29.1nC at 10V) support efficient PWM control at frequencies up to 500kHz.
The device integrates a robust body diode with 30.6ns reverse-recovery time and 28.1nC QRR, enabling synchronous rectification in buck converters without external Schottky diodes. Thermal design is anchored by RθJC = 2.5°C/W to the exposed drain pad, supporting >50W continuous dissipation when mounted on a 1-inch² 2oz copper pad.
Key Specifications

|---|---|
| VDSS | 40V - Withstands transients up to 32V in 12V automotive systems without avalanche breakdown. |
| RDS(ON) @ 10V | 7.3mΩ max - Enables <1.5W conduction loss at 70A, critical for high-current DC-DC output stages. |
| RDS(ON) @ 4.5V | 9.8mΩ max - Ensures stable on-state performance with 5V logic-level gate drivers in body control modules. |
| ID (TC=25°C) | 70A - Supports peak load currents in starter motor drivers and HVAC blower controllers. |
| EAS | 20mJ - Absorbs inductive energy during switching transitions in solenoid and relay drive circuits. |

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 | 40V, 220A, 1.6mΩ @ 10V, PowerFLAT 5x6 package; higher current but larger footprint and no AEC-Q101 documentation publicly available. | Targeted at high-power inverters rather than space-constrained body electronics; requires larger thermal pad and different layout. | Select when >100A peak current is required and board area permits 5x6mm footprint; verify PPAP status directly with STMicroelectronics. |
| IXTP44N10P | 100V, 44A, 24mΩ @ 10V, TO-220 package; higher voltage rating but significantly higher RDS(ON) and no AEC-Q101 qualification. | Suitable for industrial 24V systems but not certified for automotive production; lacks PPAP and IATF 16949 traceability. | Use only for non-automotive prototyping or cost-sensitive industrial DC-DC where AEC-Q101 is not mandated. |
Compared with STL220N4F7AG and IXTP44N10P, the DMTH4007LK3Q-13 uniquely balances AEC-Q101 compliance, TO252 manufacturability, and 7.3mΩ/4.5V drive in a single solution-making it optimal for volume automotive designs requiring zero-change qualification and compact thermal design.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMTH4007LK3Q-13 supports 51A continuous drain current at TC = +100°C with VGS = 10V, as specified in the Absolute Maximum Ratings table. This value assumes proper PCB thermal design with ≥1-inch² 2oz copper connected to the exposed drain pad.
Does this MOSFET require a gate resistor for automotive PWM applications?
Yes-a 3Ω gate resistor is used in the datasheet's switching time test conditions (tD(ON), tR). For 200–500kHz DC-DC operation, a 2.2–4.7Ω resistor balances EMI suppression and switching speed; values below 1.5Ω risk ringing due to low gate resistance (0.1–1.8Ω typical).
Is the body diode suitable for synchronous rectification?
Yes-the body diode has 30.6ns reverse-recovery time and 28.1nC QRR at IF = 20A, enabling use in synchronous buck topologies up to 300kHz. However, external Schottky diodes remain preferred for >400kHz operation due to lower QRR and zero recovery loss.
Can this part replace the DMTH4007LK3-13 in existing designs?
Yes-the DMTH4007LK3Q-13 is the automotive-qualified (AEC-Q101) version of the commercial DMTH4007LK3-13, sharing identical electrical specs, pinout, and TO252 package. The "Q" suffix denotes PPAP-capable manufacturing and IATF 16949 process control-no layout or firmware changes are needed for upgrade.
