Product details
Overview
DMTH4005SPSQ from Diodes Incorporated is a 40V, 100A N-channel enhancement-mode MOSFET in PowerDI5060-8 package, qualified to AEC-Q101 and rated for +175°C operation. It delivers 3.7mΩ RDS(ON) at VGS = 10V, supports 150W power dissipation at TC = +25°C, and features 49.1nC total gate charge - optimized for high-current automotive DC-DC converters and engine control modules.
For engineers reviewing the DMTH4005SPSQ datasheet, DMTH4005SPSQ pinout, DMTH4005SPSQ application, or DMTH4005SPSQ equivalent, key selection criteria include its AEC-Q101 qualification, 100% unclamped inductive switching rating, low RDS(ON) at high temperature, thermal resistance of 1°C/W (junction-to-case), and compatibility with high-ambient automotive power stages requiring robust body diode recovery (tRR = 31.8ns).
Technical Context
This MOSFET employs trench-gate silicon technology with optimized cell pitch and deep-trench isolation to achieve low on-resistance while maintaining rugged avalanche capability (EAS = 132.3mJ). Its gate threshold voltage (2–4V) enables reliable turn-on with standard 5V or 10V logic-level drivers in automotive power rails.
The device integrates an intrinsic body diode with 0.88V forward voltage at 50A and exhibits stable RDS(ON) over temperature (normalized to 2.0× at 175°C), supported by a 1°C/W RθJC path through the exposed drain pad - critical for thermally constrained under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage compatible with 12V/24V automotive battery systems with transient margin |
| RDS(ON) max | 3.7mΩ @ VGS = 10V - Enables <1.85W conduction loss at 70A continuous current |
| ID (TC = +25°C) | 100A - Package-limited continuous drain current enabling high-power synchronous rectification |
| Qg | 49.1nC - Low gate charge reduces driver power demand and switching energy in 100kHz–500kHz DC-DC stages |
| EAS | 132.3mJ - Confirmed avalanche energy rating ensures reliability during inductive load switching transients |
| tRR | 31.8ns - Fast body diode recovery minimizes shoot-through risk and commutation losses in half-bridge topologies |
| TJ max | +175°C - Extended junction temperature rating supports operation in engine bay environments without derating |
Pinout & Package

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, RDS(ON) = 1.6mΩ @ 10V, PowerFLAT 5x6 package, RθJC = 0.7°C/W | Higher current rating but larger footprint; requires more PCB area and higher gate drive current (Qg = 105nC) | Select when >150A peak current or lower thermal resistance is required; not drop-in due to different pinout and layout |
| IXTP100N044T | 44V, 100A, RDS(ON) = 4.4mΩ @ 10V, TO-220AB package, RθJC = 0.9°C/W, non-AEC-Q101 | Through-hole package with inferior thermal performance in SMT assemblies; lacks automotive qualification and PPAP support | Acceptable for industrial prototypes or cost-sensitive non-automotive designs; unsuitable for production automotive programs |

FAQ
Is DMTH4005SPSQ qualified for automotive use?
Yes, DMTH4005SPSQ is fully AEC-Q101 qualified, manufactured in IATF 16949 certified facilities, and supported by PPAP documentation. It meets stringent automotive reliability standards including temperature cycling, humidity testing, and mechanical shock validation - confirmed in Diodes' DS38159 datasheet Rev. 3-2.
What is the thermal resistance from junction to case (RθJC)?
The junction-to-case thermal resistance is 1°C/W, measured from the silicon die to the exposed drain pad of the PowerDI5060-8 package. This value is validated under standard test conditions (Note 6 in DS38159) and enables 150W power dissipation at TC = +25°C without exceeding TJ = +175°C.
Does DMTH4005SPSQ have a specified body diode reverse recovery time?
Yes, the body diode reverse recovery time (tRR) is specified as 31.8ns under test conditions of IF = 50A and di/dt = 100A/μs. This parameter is guaranteed and measured per JEDEC standards, confirming suitability for high-frequency synchronous rectification and half-bridge topologies.
Can DMTH4005SPSQ be used in a high-side configuration?
Yes, DMTH4005SPSQ can operate in high-side configurations when paired with a gate driver capable of providing VGS ≥ 10V referenced to the source node. Its ±20V VGSS rating and 4V maximum VGS(TH) ensure reliable turn-on even with bootstrap voltage droop in typical automotive high-side gate drive circuits.
