Product details
Overview
DMTH4004SPS from Diodes Incorporated is a 40V, 185A N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for continuous operation at +175°C junction temperature, with RDS(ON) = 2.7 mΩ @ VGS = 10 V and Qg = 68.6 nC - optimized for high-current DC-DC converters and automotive body control modules.
For engineers reviewing the DMTH4004SPS datasheet, DMTH4004SPS pinout, DMTH4004SPS application, or DMTH4004SPS equivalent, key selection criteria include its AEC-Q-qualified reliability, low RDS(ON) at high temperature, unclamped inductive switching rating, and thermal resistance of 0.9°C/W (junction-to-case), critical for thermally constrained power stages.
Technical Context
This MOSFET employs trench-gate silicon technology to achieve ultra-low on-resistance while maintaining robust switching performance. Its 100% unclamped inductive switching (UIS) rating of 45 A / 200 mJ ensures survivability under transient overcurrent conditions common in automotive load switching.
The device features a thermally enhanced PowerDI5060-8 package with exposed drain pad for direct PCB heat sinking, enabling 167 W total power dissipation at TC = +25°C. Gate threshold voltage (2–4 V) and low gate resistance (0.77 Ω) support fast, predictable turn-on with standard 10 V gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage for 12 V/24 V automotive and industrial bus applications. |
| RDS(ON) | 2.7 mΩ @ VGS = 10 V - Enables <1.5 W conduction loss at 90 A, reducing heatsink requirements. |
| Qg | 68.6 nC - Low gate charge minimizes driver power and switching energy loss in high-frequency (>100 kHz) converters. |
| TJ max | +175°C - Qualified per AEC-Q101, supporting engine bay and transmission control environments. |
| ID (TC = 25°C) | 185 A - Continuous drain current rating based on thermal limit at solder point, not ambient. |
| RθJC | 0.9°C/W - Junction-to-case thermal resistance enables efficient heat transfer to external copper planes or heatsinks. |
| Ciss | 4305 pF - Input capacitance impacts gate drive loop stability and Miller effect during hard switching. |
Pinout & Package
Package: PowerDI5060-8 - surface-mount, thermally enhanced 8-pin molded plastic package with exposed drain pad (pins 2, 4, 5, 6, 7 connected internally to drain). UL 94V-0 rated, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Source | Main source terminal; electrically isolated from drain and gate; connects to low-side return path. |
| Pins 2, 4, 5, 6, 7 | Drain | Internally paralleled drain terminals; tied to exposed metal pad for thermal and electrical conduction. |
| Pin 3 | Gate | Control input; requires 10 V for full enhancement; gate threshold 2–4 V enables TTL/CMOS-compatible driving. |
| Pins 8, S (exposed pad) | Source (thermal) | Secondary source connection via soldered thermal pad; improves mechanical stability and thermal coupling to PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per JEDEC standards, including temperature cycling, HTRB, and UIS stress testing. |
| 100% UIS tested | Each unit screened for unclamped inductive switching up to 45 A / 200 mJ - eliminates field failure due to inductive kickback. |
| Low RDS(ON) at +175°C | RDS(ON) increases only ~1.8× from 25°C to 175°C (per Figure 6), ensuring stable conduction loss in hot environments. |
| Green, lead-free construction | Meets RoHS 3 and Diodes' "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb); matte tin annealed finish ensures reliable solderability. |
| Optimized dynamic parameters | Qgd/Qg = 0.207 - low ratio reduces Miller plateau duration and improves switching controllability. |
Applications
| Engine Control Unit (ECU) Power Stages | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXTP40N40P | 400 V, 40 A, TO-220 package; RDS(ON) = 100 mΩ - higher voltage rating but 37× higher on-resistance. | Designed for 400 V SMPS, not 48 V automotive; lacks AEC-Q qualification and +175°C rating. | Select only if higher breakdown voltage is required and thermal constraints allow larger package. |
| STL220N4F7AG | 40 V, 220 A, PowerFLAT 5x6; RDS(ON) = 1.4 mΩ - lower RDS(ON), but Qg = 110 nC and no UIS rating published. | Optimized for ultra-high-efficiency server VRMs; not AEC-Q qualified and untested for inductive switching. | Prefer for non-automotive, high-frequency digital power where UIS robustness is secondary to conduction loss. |
Compared with IXTP40N40P and STL220N4F7AG, DMTH4004SPS uniquely balances ultra-low RDS(ON), AEC-Q101 qualification, +175°C operation, and guaranteed UIS - making it the only choice for thermally aggressive, safety-critical automotive power switching where reliability under fault conditions is mandatory.

FAQ
What is the maximum continuous drain current at +100°C case temperature?
The DMTH4004SPS supports 131 A continuous drain current when the case temperature is maintained at +100°C, as specified in the Absolute Maximum Ratings table (Note 6). This derating reflects thermal limits of the PowerDI5060-8 package's junction-to-case path and must be validated with actual PCB thermal design using the provided RθJC = 0.9°C/W value.
Is DMTH4004SPS pin-compatible with the automotive-grade DMTH4004SPSQ variant?
Yes - DMTH4004SPS and DMTH4004SPSQ share identical PowerDI5060-8 packaging, pinout, and electrical specifications. The SPQ suffix denotes AEC-Q101 qualification with extended test coverage (e.g., additional temperature cycling and HTOL), but both parts use the same die and layout; SPQ is recommended for new automotive designs requiring full qualification documentation.
Can this MOSFET replace a mechanical relay in a 24 V, 50 A load application?
Yes - with appropriate gate drive (≥10 V, ≥2 A peak), snubbing, and thermal management, DMTH4004SPS can replace relays in 24 V systems. Its 185 A continuous rating at TC = 25°C and 740 A pulsed rating exceed typical relay contact ratings, while eliminating contact wear, bounce, and acoustic noise - provided the PCB layout accommodates the exposed drain pad for heat dissipation.
Does the body diode have soft recovery characteristics suitable for synchronous rectification?
No - the body diode exhibits tRR = 52.4 ns and QRR = 78.2 nC (measured at dI/dt = 100 A/μs), indicating moderately fast but not soft recovery. It is suitable for synchronous rectification in moderate-frequency DC-DC converters, but not for zero-voltage-switching topologies requiring ultra-soft recovery; external Schottky catch diodes may be needed for EMI-sensitive designs.
