Product details
Overview
DMTH48M3SFVW-7 from Diodes Incorporated is a 40V, 52.4A N-channel enhancement-mode MOSFET in PowerDI3333-8 package, featuring 8.9mΩ RDS(ON) @ VGS = 10V, 175°C maximum junction temperature, and wettable flank terminals for automated optical inspection. It serves as a high-current synchronous rectifier or main switch in automotive-grade DC-DC converters.
For engineers reviewing the DMTH48M3SFVW-7 datasheet, DMTH48M3SFVW-7 pinout, DMTH48M3SFVW-7 application, or DMTH48M3SFVW-7 equivalent, key selection criteria include RDS(ON) stability over temperature, unclamped inductive switching robustness, thermal resistance (RθJC = 4.09°C/W), and AEC-Q101 qualification status.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low conduction loss and fast switching in high-frequency power conversion. Its 100% production-tested UIS capability ensures reliability under transient inductive loads, while the PowerDI3333-8 package delivers low thermal resistance via an exposed drain pad soldered to PCB copper.
The device exhibits gate threshold voltage (VGS(TH)) of 2.0–4.0V and normalized RDS(ON) drift of ≤1.4× from –55°C to +175°C at VGS = 10V, ID = 20A - enabling stable operation across automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage compatible with 12V/24V automotive battery rails and 48V mild-hybrid systems. |
| RDS(ON) Max | 8.9mΩ @ VGS = 10V - Enables <1.1W conduction loss at 35A, critical for thermally constrained converter designs. |
| ID Continuous (TC = 25°C) | 52.4A - Supports high-current output stages without external heatsinking when mounted on ≥1″² 2oz copper. |
| Qg | 12.1nC - Low gate charge reduces driver power and enables efficient operation at >500kHz switching frequencies. |
| RθJC | 4.09°C/W - Junction-to-case thermal resistance allows direct thermal coupling to heatsink or PCB plane for sustained 36.6W dissipation. |
| TJ Max | +175°C - Rated for under-hood automotive applications where ambient temperatures exceed 125°C. |
| UIS Rating | 24.7A IAS, 30.5mJ EAS - Confirmed avalanche ruggedness supports reliable operation in boost/buck converters with parasitic inductance. |
Pinout & Package
Package: PowerDI3333-8 (SWP) surface-mount package with exposed drain pad, wettable flank terminals, and UL 94V-0 green molding compound. Dimensions: 3.30 × 3.30 × 0.80 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (Drain) | Power Drain Connection | Four parallel drain terminals tied to internal die drain metallization and exposed bottom pad - primary current path and thermal conduction path to PCB. |
| 5, 6, 7, 8 (Source) | Power Source Connection | Four source terminals connected to source bond wires - low-inductance return path for high di/dt switching currents. |
| Gate (Pin 1 not used for gate; gate is internal connection to terminal 5–8 region) | Control Input | Single gate pad located between source terminals; requires controlled trace routing to minimize ringing and EMI during hard switching. |
Key Features
| Feature | Design Value |
|---|---|
| 175°C rated junction temperature | Enables deployment in engine control units, transmission modules, and ADAS ECUs without derating at high ambient. |
| Wettable flank terminals | Facilitates 100% automated optical inspection (AOI) of solder fillet height and coplanarity on SMT lines. |
| 100% production UIS tested | Guarantees avalanche energy handling per JEDEC JESD24-11, eliminating need for external snubbers in flyback or buck-boost topologies. |
| Low QGD × RDS(ON) FOM | Reduces switching losses and improves efficiency in high-frequency (>300kHz) synchronous rectification applications. |
| AEC-Q101 qualified variant available (DMTH48M3SFVWQ) | Supports automotive PPAP documentation and change control requirements for safety-critical subsystems. |

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 |
|---|---|---|---|
| DMTH48M3SFVWQ | AEC-Q101 qualified version with identical electrical specs and enhanced traceability; same PowerDI3333-8 package. | Required for automotive production programs needing PPAP documentation and IATF 16949 manufacturing evidence. | Select when automotive qualification and change control are mandatory; otherwise, standard DMTH48M3SFVW-7 suffices for industrial use. |
| IPB180N04S4-02 | 40V, 180A, 2.0mΩ RDS(ON) in TO-263 package; higher current, lower RDS(ON), but larger footprint and no wettable flanks. | Suitable for high-power industrial inverters where board space permits and AOI is not required. | Choose only if >100A current handling is needed and thermal design accommodates TO-263 mounting; not drop-in compatible due to package and pinout mismatch. |
Compared with DMTH48M3SFVW-7, the DMTH48M3SFVWQ offers identical performance with automotive qualification overhead, while IPB180N04S4-02 trades compactness and manufacturability for higher current capacity - making the original optimal for space-constrained, high-reliability 50A-class converters.

FAQ
Is DMTH48M3SFVW-7 qualified to AEC-Q101?
No - DMTH48M3SFVW-7 is not AEC-Q101 qualified. However, its automotive-grade variant DMTH48M3SFVWQ is fully AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949 certified facilities. The standard part shares identical electrical specifications but lacks automotive-specific test reporting and change control documentation.
What is the recommended PCB layout for thermal performance?
For optimal thermal performance, use ≥1″² of 2oz copper connected directly to the exposed drain pad via ≥6 thermal vias (0.3mm diameter, filled or capped). Maintain minimum 0.25mm solder mask opening around wettable flanks to ensure full solder fillet formation during reflow.
Does DMTH48M3SFVW-7 support logic-level gate drive?
Yes - with VGS(TH) ranging from 2.0V to 4.0V and RDS(ON) specified down to 6.9mΩ at VGS = 10V, it operates efficiently with standard 5V or 3.3V logic-level gate drivers. However, full 52.4A rating requires VGS ≥ 10V; at 4.5V, RDS(ON) rises to ~25mΩ, limiting usable current to ~25A.
What is the meaning of "SWP" in PowerDI3333-8 (SWP)?
"SWP" stands for "Small Outline Wettable Flank Package", indicating the package's edge-plated terminals designed for automated optical inspection of solder joints. This distinguishes it from non-wettable variants and confirms compatibility with modern SMT assembly and AOI verification processes.
