Product details
Overview
DMNH4005SPSQ-13 from Diodes Incorporated is a 40V N-channel TrenchMOS™ power MOSFET in PowerDI5060-8 package, rated for 80A continuous drain current at TC = +25°C, with RDS(ON) of 4.0 mΩ at VGS = 10V and qualified to AEC-Q101 for automotive use. It delivers robust unclamped inductive switching (UIS) performance (IAS = 30A, EAS = 445 mJ), operates up to +175°C junction temperature, and is deployed in engine management systems and DC-DC converters where high-current, low-loss switching is critical.
For engineers reviewing the DMNH4005SPSQ-13 datasheet, DMNH4005SPSQ-13 pinout, DMNH4005SPSQ-13 application, or DMNH4005SPSQ-13 equivalent, key selection criteria include its 4.0 mΩ on-resistance at 10V gate drive, 175°C thermal rating, PowerDI5060-8 thermal performance (RθJC = 0.9°C/W), AEC-Q101 qualification, and suitability for high-reliability automotive power stages requiring low Qg (48 nC) and fast switching (tD(OFF) = 18.3 ns).
Technical Context
This MOSFET uses Diodes' proprietary TrenchMOS™ process to achieve low RDS(ON) and optimized charge characteristics. Its internal structure features eight parallel die with dual-source/dual-drain layout in PowerDI5060-8, enabling high current handling while maintaining low thermal resistance (RθJC = 0.9°C/W) and stable operation across -55°C to +175°C.
The device supports gate drive voltages from 4.5V to 10V, with VGS(TH) ranging 1–3V and tightly controlled threshold variation over temperature (±0.3V from -55°C to +175°C). Its 100% UIS-rated ruggedness and low Crss (243 pF) support reliable hard-switching in automotive DC-DC and motor control topologies without external snubbing.
Key Specifications

| VDSS | 40 V - Maximum blocking voltage before avalanche conduction; defines safe operating range in 12V/24V automotive systems. |
| RDS(ON) | 4.0 mΩ @ VGS = 10V - Enables <1.6W conduction loss at 80A; critical for minimizing heat generation in compact power modules. |
| ID (TC = +25°C) | 80 A - Continuous current capability under ideal heatsink conditions; supports high-power buck converter primary switches. |
| Qg | 48 nC @ VGS = 10V - Determines gate driver power requirement and switching speed; enables efficient 100–500 kHz operation. |
| TJ Range | -55°C to +175°C - Validated operation across full automotive ambient range; eliminates derating in under-hood applications. |
| EAS | 445 mJ - Energy-handling capacity during inductive turn-off; ensures reliability in solenoid drivers and motor phase legs without external clamping. |
| RθJC | 0.9°C/W - Thermal resistance from junction to case; enables direct mounting to copper planes or heatsinks for high-power density designs. |
Pinout & Package
Package: PowerDI5060-8 - thermally enhanced surface-mount package with exposed copper thermal pad, 1.0 mm profile, and RoHS-compliant matte tin finish over copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (S) | Source | Primary current return path; electrically tied to thermal pad; requires low-impedance PCB copper pour for thermal and electrical performance. |
| Pin 2 (D) | Drain | Main high-side power node; connected internally to 4 drain terminals for current sharing and reduced parasitic inductance. |
| Pin 3 (D) | Drain | Parallel drain connection; improves current distribution and reduces package-level RDS(ON) contribution. |
| Pin 4 (G) | Gate | Control input; low gate resistance (2.0 Ω) minimizes ringing; requires stable 10V drive for full RDS(ON) specification. |
| Pin 5 (D) | Drain | Third drain terminal; part of 8-terminal internal configuration optimizing thermal and electrical symmetry. |
| Pin 6 (D) | Drain | Fourth drain terminal; contributes to low-inductance, high-current path from die to PCB. |
| Pin 7 (S) | Source | Secondary source connection; ties to same potential as Pin 1; enhances current sharing and reduces source inductance. |
| Pin 8 (S) | Source | Third source terminal; completes low-impedance return path; critical for minimizing VGS instability during fast switching. |

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 |
|---|---|---|---|
| IXTQ48N25L2 | 250V VDSS, 48A ID, TO-264 package, RDS(ON) = 22 mΩ - higher voltage rating but lower current and larger footprint. | Used in industrial 200V DC bus applications; not AEC-Q101 qualified; lacks UIS rating and 175°C operation. | Select only if 250V blocking is required and automotive qualification is unnecessary; unsuitable for space-constrained automotive modules. |
| STL220N4LF8AG | 40V VDSS, 220A ID, PowerFLAT 5x6 package, RDS(ON) = 1.2 mΩ - lower RDS(ON) but higher Qg (120 nC) and no documented UIS rating. | Targeted at high-current battery disconnects; lacks AEC-Q101 documentation and PPAP support; thermal resistance higher (RθJC = 1.2°C/W). | Prefer for ultra-low-loss battery switching where gate drive strength permits; avoid in inductive load applications without external protection. |
Compared with IXTQ48N25L2 and STL220N4LF8AG, DMNH4005SPSQ-13 uniquely balances 80A current, 4.0 mΩ on-resistance, AEC-Q101 qualification, 445 mJ UIS, and 0.9°C/W thermal resistance in a low-profile package-making it optimal for thermally constrained, safety-critical automotive power stages.

FAQ
What is the maximum continuous drain current at TC = +100°C?
The DMNH4005SPSQ-13 supports 60A continuous drain current when case temperature is maintained at +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerDI5060-8 package and must be verified using actual PCB thermal design with 2oz copper and thermal vias.
Is the PowerDI5060-8 package lead-free and RoHS compliant?
Yes - the DMNH4005SPSQ-13 uses matte tin annealed over copper leadframe, meeting EU RoHS Directive 2015/863/EU (RoHS 3), with halogen and antimony content below 900 ppm bromine/chlorine and 1000 ppm antimony, certified as "Green" per Diodes' definitions.
Does this MOSFET require a gate resistor for automotive applications?
A gate resistor (typically 2–10 Ω) is recommended to dampen ringing caused by PCB trace inductance and low gate resistance (2.0 Ω), especially in high-di/dt environments like fuel injector drivers. Values must be validated against measured VGS overshoot and switching loss trade-offs in the target layout.
Can DMNH4005SPSQ-13 replace older DMP4005LKQ-13 in existing designs?
No - DMP4005LKQ-13 uses PowerDI3333 package (RθJC = 2.0°C/W, ID = 50A), while DMNH4005SPSQ-13 uses PowerDI5060-8 with different pinout, thermal pad geometry, and higher current rating. Layout redesign and thermal validation are required; it is not a drop-in replacement.
