Product details
Overview
DMP4026SFVW-7 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for -49A at TC = +25°C, with RDS(ON) of 25 mΩ @ VGS = -10V and 45 mΩ @ VGS = -4.5V. It delivers low on-resistance and robust UIS capability (IAS = -27A, EAS = 109 mJ), enabling high-efficiency reverse-polarity protection and DC-DC converter power switches.
For engineers reviewing the DMP4026SFVW-7 datasheet, DMP4026SFVW-7 pinout, DMP4026SFVW-7 application, or DMP4026SFVW-7 equivalent, key selection criteria include its thermally efficient PowerDI3333-8 footprint, -40V VDSS, gate threshold range (-0.8 to -1.8 V), body diode forward voltage (0.7–1.0 V), and junction-to-case thermal resistance (1.25 °C/W).
Technical Context
This P-channel MOSFET operates as a high-side load switch or reverse-battery protection device, leveraging its negative VGS(th) and low RDS(ON) to minimize conduction loss in 12V/24V automotive and industrial power rails. Its 100% production-tested UIS rating ensures reliability under inductive switching stress.
The device uses an optimized trench-gate structure to balance RDS(ON) and gate charge (Qg = 45.8 nC @ VGS = -10V), supporting fast turn-on/off times (tD(ON) = 4.3 ns, tF = 23.9 ns) while maintaining low Ciss (2064 pF) and Crss (182 pF) for stable gate drive behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Withstands up to 40V reverse drain-source voltage without breakdown, suitable for 24V automotive systems with load dump margins. |
| RDS(ON) @ VGS = -10V | 25 mΩ - Enables ≤1.2 W conduction loss at -37A, critical for high-current reverse-polarity protection circuits. |
| ID (TC = +25°C) | -49 A - Continuous drain current rating at case temperature, defining maximum steady-state power-switching capability. |
| Qg @ VGS = -10V | 45.8 nC - Total gate charge determines required driver strength and switching energy in high-frequency DC-DC applications. |
| RθJC | 1.25 °C/W - Junction-to-case thermal resistance enables direct heatsinking via exposed drain pad for high-power operation. |
| EAS | 109 mJ - Avalanche energy rating supports reliable operation during inductive load switching without external snubbers. |
| VGS(th) | -0.8 to -1.8 V - Gate threshold range ensures predictable turn-on with standard logic-level control signals (e.g., microcontroller GPIO). |
Pinout & Package
Package: PowerDI3333-8 (SWP, Type UX), surface-mount, thermally enhanced with exposed drain pad. Dimensions: 3.30 × 3.30 × 0.80 mm (L × W × H), moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 (Drain) | Drain (D) | All eight pins are internally connected to the drain terminal and exposed copper pad - provides low-inductance, high-current path and primary thermal conduction path to PCB. |
| Source (S) | Source (S) | Terminal 1 (top view marking indicator) is source - used as return path for load current and reference for gate drive. |
| Gate (G) | Gate (G) | Terminal 2 (adjacent to source) - controls channel conduction; requires negative VGS relative to source for turn-on. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 4.5V drive | 45 mΩ - Enables use with 5V logic controllers without level-shifting, reducing BOM count in compact power modules. |
| Thermally optimized package | RθJC = 1.25 °C/W - Allows >3× higher power dissipation than SO-8 equivalents under identical PCB layout conditions. |
| Board area reduction | 33% of SO-8 footprint - Frees PCB space for additional circuitry or smaller end-product form factors in space-constrained designs. |
| 100% UIS tested | IAS = -27A, EAS = 109 mJ - Guarantees ruggedness against inductive kickback in motor drivers and hot-swap circuits without derating. |
| Green, RoHS-compliant construction | Halogen- and antimony-free, <900 ppm Br/Cl - Meets automotive and industrial environmental compliance requirements without performance trade-offs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT4006LPS-13 | RDS(ON) = 3.2 mΩ @ -10V (lower), but rated only for -40V and packaged in PowerDI5060 (larger, 5.0 × 6.0 mm). | Higher current density but requires more PCB area and different thermal layout; not drop-in compatible. | Select when peak current exceeds 49A and board space allows larger footprint. |
| SiR466DP-T1-GE3 | RDS(ON) = 22 mΩ @ -10V (slightly lower), 40V rating, PowerPAK® SO-8 package with RθJA = 45 °C/W (less efficient thermal path). | Larger RθJA limits continuous power in confined layouts; lacks 100% UIS test documentation. | Prefer for legacy SO-8 designs where re-layout is impractical and avalanche testing is non-critical. |
Compared with DMT4006LPS-13 and SiR466DP-T1-GE3, DMP4026SFVW-7 offers optimal balance of ultra-compact size, verified avalanche ruggedness, and thermal performance - making it ideal for new designs prioritizing board area, reliability, and thermal management in automotive and industrial power switches.

FAQ
What is the maximum continuous drain current at 70°C case temperature?
The DMP4026SFVW-7 supports -39 A continuous drain current at TC = +70°C with VGS = -10V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerDI3333-8 package under sustained high-temperature operation, and must be validated against actual PCB thermal design using RθJC = 1.25 °C/W.
Does this MOSFET require a gate resistor for stability in switching applications?
A gate resistor (typically 5–22 Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 182 pF) and PCB trace inductance. The device's low gate resistance (Rg = 2.5 Ω) and fast switching times (tF = 23.9 ns) make it susceptible to oscillation without proper gate drive impedance control.
Can DMP4026SFVW-7 be used in automotive applications requiring AEC-Q101 qualification?
No - the DMP4026SFVW-7 is not AEC-Q101 qualified. Diodes states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; this part is intended for industrial and commercial applications. For AEC-Q101, consult Diodes' APxxxx or DMPxxx-AQ product families.
How does the PowerDI3333-8 package improve thermal performance over SO-8?
The PowerDI3333-8 exposes the drain pad directly to the PCB, achieving RθJC = 1.25 °C/W - over 5× better than typical SO-8 RθJC (~7–10 °C/W). Its 3.3 mm × 3.3 mm footprint also reduces thermal spreading resistance, allowing higher power density without external heatsinks in properly designed 2-oz copper layouts.
