Product details
Overview
DMTH4005SK3Q-13 from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for 40V VDSS, 4.5mΩ RDS(ON) @ 10V VGS, and 95A continuous drain current at TC = +25°C. It operates up to +175°C junction temperature and is designed for high-reliability automotive power switching in engine management and DC-DC converters.
For engineers reviewing the DMTH4005SK3Q-13 datasheet, DMTH4005SK3Q-13 pinout, DMTH4005SK3Q-13 application, or DMTH4005SK3Q-13 equivalent, key selection criteria include its 1.5°C/W RθJC, 49.1nC total gate charge, 100% unclamped inductive switching rating, and PPAP-capable automotive qualification status.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction and switching losses in high-current automotive power stages. Its 3.6mΩ typical RDS(ON) at 10V gate drive enables efficient operation in 12V/24V battery-fed systems, while the 175°C rating supports placement near hot engine compartments without derating.
The device integrates a robust body diode with 31.8ns reverse recovery time and 26.5nC QRR, supporting synchronous rectification and freewheeling in buck and half-bridge topologies. Its 3,062pF Ciss and 179.2pF Crss support stable gate driving with standard 3Ω external gate resistors under 20V VDD conditions.
Key Specifications

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, 2.2mΩ RDS(ON), 220A ID, PowerFLAT 5x6 package, higher current but larger footprint | Better suited for high-power inverters requiring >150A; less optimal for space-constrained DPAK layouts | Select when board area allows larger package and higher current headroom is needed beyond 95A |
| IXTP40N40P | 400V, 40mΩ RDS(ON), TO-220 package, non-automotive grade, no AEC-Q101 | Designed for industrial SMPS, not qualified for automotive use; lacks PPAP and 175°C rating | Only consider for non-automotive prototypes or cost-sensitive industrial designs where qualification is not required |
Compared with STL220N4F7AG and IXTP40N40P, DMTH4005SK3Q-13 uniquely balances AEC-Q101 compliance, DPAK form factor, 4.5mΩ conduction loss, and 175°C operation-making it optimal for volume automotive power stages where footprint, qualification, and thermal resilience are jointly constrained.

FAQ
What is the maximum allowable gate-source voltage for DMTH4005SK3Q-13?
The absolute maximum VGS is ±20V. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be limited to +10V to +15V for full enhancement and –5V to –10V for fast turn-off, with transient spikes clamped using Zener diodes or gate drivers with built-in protection.
Is DMTH4005SK3Q-13 suitable for synchronous rectification in a 48V automotive DC-DC converter?
Yes. With its 0.9V body diode forward voltage, 31.8ns reverse recovery time, and 4.5mΩ RDS(ON), it delivers low conduction and recovery losses in secondary-side synchronous rectification. Its 175°C rating also supports high-temperature converter operation near engines or batteries.
Does DMTH4005SK3Q-13 require a heatsink in a 95A application?
At 95A continuous, junction temperature will exceed safe limits without thermal management. The 1.5°C/W RθJC requires a low-thermal-resistance interface (e.g., thermal pad or solder) to a heatsink or large copper plane. Derating to ~73A is necessary at TC = +100°C per datasheet specifications.
How does the 100% UIS rating impact system-level reliability?
The 100% unclamped inductive switching validation means the device can safely absorb the stored inductive energy (E = ½L·I²) during turn-off without breakdown-even without external snubbers. This eliminates single-point failure modes in solenoid, relay, and motor control circuits where inductive kickback is unavoidable.
