Product details
Overview
DMN6040SK3Q-13 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET qualified to AEC-Q101, with RDS(ON) = 40 mΩ @ VGS = 10 V, ID = 20 A at TC = +25°C, and TO252 (DPAK) package. It serves as a high-efficiency power switch in automotive DC-DC converters and power-management circuits requiring robust thermal performance and low conduction loss.
For engineers reviewing the DMN6040SK3Q-13 datasheet, DMN6040SK3Q-13 pinout, DMN6040SK3Q-13 application, or DMN6040SK3Q-13 equivalent, key selection criteria include its AEC-Q101 qualification, 40 mΩ on-resistance at 10 V gate drive, 30 A pulsed drain current capability, and suitability for thermally constrained automotive power stages.
Technical Context
This MOSFET employs planar trench-gate technology optimized for low RDS(ON) and fast switching in 12 V/24 V automotive systems. Its gate threshold voltage (1–3 V) ensures reliable turn-on with standard logic-level drivers, while low Ciss (1287 pF) and Qg (22.4 nC @ 10 V) support high-frequency operation up to 500 kHz in synchronous buck topologies.
The device integrates a body diode with tRR = 18 ns and QRR = 11.9 nC, enabling efficient freewheeling in hard-switched converters. Thermal resistance RθJC = 3°C/W allows 42 W power dissipation at TC = +25°C, supporting compact heatsinkless designs when mounted on 2 oz copper FR-4 with 1-inch² pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Withstands peak bus transients in 24 V automotive systems without avalanche breakdown. |
| RDS(ON) | 40 mΩ @ VGS = 10 V - Enables ≤0.8 W conduction loss at 20 A, reducing thermal load in power rails. |
| ID (TC = +25°C) | 20 A - Supports continuous output currents in 100–200 W DC-DC modules without derating. |
| Qg | 22.4 nC @ VGS = 10 V - Requires ≤1.12 µC gate drive energy per cycle at 500 kHz, minimizing driver losses. |
| tRR | 18 ns - Limits reverse-recovery di/dt-induced voltage spikes and EMI in synchronous rectification. |
| RθJC | 3°C/W - Delivers 14°C temperature rise per watt at junction-to-case interface, enabling direct heatsink mounting. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive under-hood applications including HTOL, TC, and HAST. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, 3-terminal plastic molded case with exposed drain pad for thermal conduction. UL 94V-0 rated, matte tin-plated copper leadframe, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output / thermal interface | Exposed metal tab electrically connected to drain; must be soldered to large copper pour for thermal management and electrical return. |
| Source | Reference node for gate control / current return | Low-inductance source connection critical for stable gate drive and minimizing shoot-through risk in half-bridge configurations. |
| Gate | Control input for channel modulation | High-impedance input requiring <100 nA leakage; layout must minimize trace inductance to prevent oscillation during fast switching. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 60 V automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL60N3LLH6 | RDS(ON) = 3.3 mΩ @ 10 V (lower), but SO-8FL package limits thermal dissipation to 2.5 W (RθJA = 50°C/W). | Better for low-power, space-constrained modules (<5 W); unsuitable for >5 A continuous loads due to package thermal limit. | Select when board area is critical and power <3 W; avoid for DC-DC primary switches above 3 A. |
| IXTP50N065T | TO-220 package, RDS(ON) = 6.5 mΩ @ 10 V, but not AEC-Q101 qualified; RθJC = 1.5°C/W. | Higher power handling (100 W), but requires external qualification effort and fails automotive PPAP requirements. | Acceptable for industrial or commercial prototypes; reject for production automotive programs requiring certified change control. |
Compared with STL60N3LLH6 and IXTP50N065T, the DMN6040SK3Q-13 uniquely balances AEC-Q101 compliance, 40 mΩ on-resistance, and TO252 thermal capability-making it optimal for mid-power automotive DC-DC stages where qualification, efficiency, and manufacturability must coexist.

FAQ
What is the maximum continuous drain current at TC = +100°C?
The DMN6040SK3Q-13 supports 13 A continuous drain current at case temperature +100°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO252 package and must be validated against actual PCB layout and ambient conditions using RθJC = 3°C/W and RθJA = 44°C/W values.
Is the body diode suitable for synchronous rectification?
No-the body diode is not optimized for synchronous rectification. Its reverse recovery time (tRR = 18 ns) and charge (QRR = 11.9 nC) are designed for freewheeling in non-synchronous topologies. For synchronous rectification, an external Schottky or dedicated synchronous MOSFET with lower QRR is recommended.
Does this part support 3.3 V gate drive in automotive applications?
Yes-RDS(ON) is specified at 58 mΩ @ VGS = 4.5 V and ID = 12 A, confirming usable conduction with 3.3 V logic-level drivers when paired with appropriate gate resistors and layout. However, full 20 A capability requires ≥10 V gate drive.
What is the moisture sensitivity level (MSL) and reflow profile requirement?
The DMN6040SK3Q-13 has MSL Level 3 per J-STD-020, requiring floor life of 168 hours at ≤30°C/60% RH before reflow. Standard lead-free reflow profile applies: peak temperature 260°C, time above 217°C ≤60 seconds, ramp rate ≤3°C/s. Refer to Diodes' packaging documentation for full profile details.
