Product details
Overview
DMTH4004SPSWQ from Diodes Incorporated is a 40V, 185A N-channel enhancement-mode MOSFET in PowerDI5060-8/SWP package, rated for +175°C operation, with RDS(ON) = 2.3 mΩ (typ) at VGS = 10 V and Qg = 68.6 nC, designed for high-current automotive DC-DC converters and engine management systems.
For engineers reviewing the DMTH4004SPSWQ datasheet, DMTH4004SPSWQ pinout, DMTH4004SPSWQ application, or DMTH4004SPSWQ equivalent, this AEC-Q101-qualified device supports high-temperature under-hood deployment, low conduction loss, robust unclamped inductive switching, and IATF 16949-manufactured traceability.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-current automotive power stages. Its 100% unclamped inductive switching (UIS) rating of 45 A / 200 mJ ensures survivability during transient overloads in motor control and converter circuits.
The device features a thermally enhanced PowerDI5060-8/SWP package with exposed drain pad, delivering RθJC = 0.9 °C/W and enabling 167 W continuous power dissipation at TC = +25°C - critical for compact, high-efficiency power modules requiring minimal heatsinking.

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 @ 10 V; Qg = 72 nC; same PowerFLAT 5x6 package | Higher gate charge increases driver loss; identical thermal resistance but lower UIS rating (150 mJ) | Prefer when existing STMicro design reuse is prioritized over marginal switching efficiency gain |
| IXTP180N045T | RDS(ON) = 4.5 mΩ @ 10 V; TO-220 package; RθJC = 0.45 °C/W but no AEC-Q101 qualification | Higher conduction loss; discrete heatsink required; not approved for automotive production | Acceptable only for industrial prototyping where qualification is not mandated |
Compared with STL220N4F7AG and IXTP180N045T, DMTH4004SPSWQ delivers superior switching efficiency via lower Qg, guaranteed automotive qualification, and higher avalanche ruggedness - making it the optimal choice for production-grade 48 V automotive power stages.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMTH4004SPSWQ supports 131 A continuous drain current at TC = +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by junction-to-case resistance (0.9 °C/W) and safe operating area constraints under sustained load conditions.
Does this MOSFET include an integrated body diode, and what is its forward voltage?
Yes, it integrates a parasitic body diode with VSD = 0.9 V (typ) at IS = 20 A and TA = +25°C. The diode is rated for 185 A continuous and 740 A pulsed forward current, and exhibits tRR = 52.4 ns under IF = 50 A / di/dt = 100 A/μs conditions.
Can DMTH4004SPSWQ be used in synchronous rectification topologies?
Yes - its low RDS(ON) (2.3 mΩ), low Qg (68.6 nC), and fast switching parameters (tr = 6.7 ns, tf = 8.1 ns) make it suitable for synchronous rectification in high-frequency DC-DC converters, provided gate drive timing accounts for its 14.2 nC Qgd and 16.8 nC Qgs.
What is the recommended PCB layout for thermal performance?
Diodes specifies mounting on 25 mm × 25 mm 2 oz copper on FR4 with the exposed drain pad fully soldered. Minimum recommended copper area is 200 mm² per drain terminal; thermal vias (≥8×0.3 mm) under the pad are strongly advised to enhance heat transfer to inner layers or heatsink.
