Product details
Overview
DMTH4004SPSQ from Diodes Incorporated is an AEC-Q101-qualified 40V N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for continuous drain current of 185A at TC = +25°C, RDS(ON) = 2.7 mΩ @ VGS = 10V, and operating up to +175°C junction temperature. It delivers low switching loss (Qg = 68.6 nC) and robust unclamped inductive switching for automotive power stages.
For engineers reviewing the DMTH4004SPSQ datasheet, DMTH4004SPSQ pinout, DMTH4004SPSQ application, or DMTH4004SPSQ equivalent, this part is selected for high-current, high-temperature DC-DC converters, engine control units, and body electronics where thermal reliability and AEC-Q101 compliance are mandatory.
Technical Context
This MOSFET uses a trench-gate silicon process optimized for low RDS(ON) and fast switching in automotive-grade packaging. Its 100% UIS-rated ruggedness supports repetitive inductive turn-off stress without derating, critical for solenoid drivers and motor phase switches.
The device integrates a low-forward-voltage body diode (VSD = 0.9 V @ IS = 20A) with tRR = 52.4 ns and QRR = 78.2 nC, enabling efficient synchronous rectification and freewheeling in buck and half-bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage before avalanche onset; suitable for 12V/24V automotive bus systems with transient margin. |
| RDS(ON) | 2.7 mΩ @ VGS = 10V - Enables ≤0.5 W conduction loss at 100A, reducing heatsink requirements in compact modules. |
| Qg | 68.6 nC - Low gate charge allows fast switching with moderate gate driver strength (e.g., 2A peak), minimizing turn-on energy loss. |
| ID (TC = +25°C) | 185 A - Continuous current rating referenced to case temperature; requires direct thermal coupling to PCB copper or heatsink. |
| TJ max | +175°C - Extended junction temperature rating enables operation in under-hood environments without thermal throttling. |
| EAS | 200 mJ - Avalanche energy capability ensures survivability during load dump or short-circuit events without external snubbers. |
| Ciss | 4305 pF - Input capacitance impacts gate drive loop stability and Miller effect; requires careful layout to avoid oscillation. |
Pinout & Package
Package: PowerDI5060-8 - thermally enhanced 8-pin molded plastic package with exposed drain pad (D) on bottom side for direct PCB thermal conduction. UL 94V-0 rated, RoHS-compliant, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6 | Drain (D) | Multiple parallel drain terminals connected internally to exposed pad; primary current path and thermal conduction path to PCB. |
| 7 | Source (S) | Main source connection; used for low-side sensing and return path in high-side configurations with level-shifting gate drive. |
| 8 | Gate (G) | Control input; requires <±20V absolute rating; low Rg (0.77 Ω) minimizes gate ringing in high-dI/dt applications. |

Use Scenario: Synchronous rectification in high-frequency (200–500 kHz) buck converter supplying 12V auxiliary systems from 48V mild-hybrid bus. IC Role / Device Role / Timing Role: Secondary-side synchronous MOSFET; commutates high RMS current with low forward voltage and fast recovery. Use Value: 0.9 V VSD and 52.4 ns tRR reduce conduction loss and reverse-recovery energy, improving efficiency by ≥1.2% versus standard Schottky alternatives. | Use Scenario: Half-bridge leg switching in three-phase EPS motor inverters, subject to high dI/dt, voltage transients, and ambient temperatures up to +125°C. IC Role / Device Role / Timing Role: High-current phase-leg switch; must survive repeated short-circuit events and operate reliably at TJ = +175°C. Use Value: +175°C rating and 0.9°C/W RθJC allow sustained 131A operation at TC = +100°C-meeting EPS thermal derating requirements without forced cooling. |
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 | RDS(ON) = 2.4 mΩ @ 10V, Qg = 72 nC, same PowerFLAT 5x6 package, AEC-Q101 qualified | Higher gate charge increases switching loss in high-frequency DC-DC; slightly better conduction but lower UIS rating (150 mJ) | Select when lowest possible RDS(ON) dominates over switching speed and avalanche margin. |
| IXTP180N045T | RDS(ON) = 4.5 mΩ @ 10V, TO-220AB package, non-AEC-Q101, RθJC = 0.5°C/W | Larger footprint, no automotive qualification, higher conduction loss, but superior thermal resistance for discrete heatsink mounting | Select for non-automotive industrial motor drives where AEC-Q101 is not required and mechanical mounting flexibility is prioritized. |
Compared with STL220N4F7AG and IXTP180N045T, DMTH4004SPSQ uniquely balances ultra-low RDS(ON), industry-leading UIS robustness, and AEC-Q101 compliance in a surface-mount thermally optimized package-making it optimal for safety-critical, space-constrained automotive power stages.

FAQ
What is the maximum continuous drain current for DMTH4004SPSQ at +100°C case temperature?
The datasheet specifies 131 A continuous drain current at TC = +100°C. This derating reflects thermal limitations of the PowerDI5060-8 package and must be validated with actual PCB copper area and airflow conditions per Figure 5 and Figure 6 in DS37562 Rev. 7-2.
Does DMTH4004SPSQ require a gate resistor for automotive ECU applications?
Yes-a gate resistor (typically 2.2–4.7 Ω) is recommended to dampen ringing caused by low Rg (0.77 Ω) and parasitic inductance in high-dI/dt injector drive circuits. Layout must minimize gate loop area and use Kelvin source connection to maintain switching stability.
Can DMTH4004SPSQ replace mechanical relays in body control modules?
Yes-its 100% UIS rating, 740 A pulsed drain current, and AEC-Q101 qualification make it suitable for solid-state relay replacement in BCMs. Designers must ensure adequate PCB copper for thermal dissipation and verify SOA compliance per Figure 12 under worst-case load profiles.
Is the PowerDI5060-8 package compatible with standard reflow profiles for lead-free assembly?
Yes-the device is RoHS-compliant with matte tin annealed finish and rated for moisture sensitivity level 1 (MSL-1). It supports JEDEC J-STD-020 standard lead-free reflow profiles, including peak temperatures up to 260°C for ≤60 seconds, provided solder paste and profile match IPC-7095 guidelines.
