Product details
Overview
DMP4026SFVW-13 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for -49A continuous drain current at TC = +25°C, with RDS(ON) of 25mΩ @ VGS = -10V and 45mΩ @ VGS = -4.5V. It serves as a high-efficiency power switch in reverse-polarity protection and DC-DC converter output stages.
For engineers reviewing the DMP4026SFVW-13 datasheet, DMP4026SFVW-13 pinout, DMP4026SFVW-13 application, or DMP4026SFVW-13 equivalent, key selection criteria include verified RDS(ON) at low gate drive (-4.5V), thermal resistance (RθJC = 1.25°C/W), UIS ruggedness (EAS = 109 mJ), and PowerDI3333-8 board-area efficiency (33% of SO-8 footprint).
Technical Context
This MOSFET employs trench-gate silicon process to achieve low on-resistance while maintaining fast switching performance: tD(ON) = 4.3 ns, tD(OFF) = 71.8 ns, and Qg = 45.8 nC at VGS = -10V. Its body diode exhibits tRR = 17.3 ns and QRR = 8.7 nC under 100 A/µs dI/dt, supporting synchronous rectification in buck converters.
The device operates across -55°C to +150°C junction temperature range, with normalized RDS(ON) variation ≤1.8× over that range at VGS = -10V. Its 100% production-tested UIS capability ensures robustness against inductive load transients in automotive and industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Withstands up to 40V reverse drain-source voltage before breakdown, suitable for 24V system rail protection. |
| RDS(ON) | 25 mΩ @ VGS = -10V - Enables <1.2W conduction loss at 7A, critical for thermally constrained PCB layouts. |
| ID (TC = +25°C) | -49 A - Supports high-current load switching when mounted on heatsinked copper planes per Note 5. |
| EAS | 109 mJ - Confirmed avalanche energy rating ensures reliable operation during unclamped inductive turn-off events. |
| RθJC | 1.25 °C/W - Low junction-to-case thermal resistance enables direct thermal coupling to PCB copper or heatsinks. |
| Qg | 45.8 nC @ VGS = -10V - Gate charge value determines driver strength requirement for <100 ns switching transitions. |
| tRR | 17.3 ns - Fast body diode recovery reduces cross-conduction losses in synchronous DC-DC topologies. |
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), weight ≈ 0.03 g.
| 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 of leadframe (visible on bottom view diagram) - connects to source node; requires proper trace routing to minimize loop inductance in switching paths. |
| Gate (G) | Gate (G) | Terminal 2 of leadframe (visible on bottom view diagram) - high-impedance control input; layout must isolate from noisy drain traces to prevent false turn-on. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at -4.5V | 45 mΩ - Enables efficient operation from standard 5V logic-level gate drivers without level-shifting circuitry. |
| PowerDI3333-8 footprint | 33% board area vs SO-8 - Reduces PCB real estate in space-constrained applications like USB-C PD adapters and portable power banks. |
| 100% UIS tested | EAS = 109 mJ - Guarantees ruggedness against repetitive inductive switching stress in motor drivers and hot-swap circuits. |
| Thermal performance | RθJC = 1.25°C/W - Allows >40W power dissipation with modest heatsinking, enabling higher current density than SO-8 equivalents. |
| Green compliance | Halogen- and antimony-free, RoHS 3 compliant - Meets automotive and industrial environmental requirements without derating penalties. |
Applications
| Reverse-Polarity Protection | DC-DC Synchronous Buck Converter |
|---|---|
Use Scenario: Input protection for 24V industrial controllers where battery or supply polarity reversal may occur during field servicing. IC Role / Device Role / Timing Role: High-side P-channel MOSFET configured as ideal diode replacement, conducting only when VIN is correctly polarized. Use Value: Eliminates 0.3–0.7V forward drop of Schottky diodes, reducing power loss by >80% at 10A and enabling cooler operation in sealed enclosures. |
Use Scenario: High-efficiency 12V-to-3.3V step-down converter in network switch PoE midspans. IC Role / Device Role / Timing Role: Synchronous rectifier (low-side switch) operating at 500 kHz with 100 ns dead-time control. Use Value: 45 mΩ RDS(ON) at -4.5V allows direct drive from PWM controller's logic-level output, removing gate driver IC and saving BOM cost. |
| Hot-Swap Circuitry | Automotive Body Control Module |
Use Scenario: Inrush-limited 12V power distribution to peripheral modules (e.g., infotainment USB ports) in server backplanes. IC Role / Device Role / Timing Role: Controlled turn-on switch with external RC gate timing, limiting dV/dt during insertion. Use Value: 1.25°C/W RθJC supports 15A steady-state current with minimal heatsink, enabling compact, fanless module design. |
Use Scenario: Load switching for interior lighting and window lift motors in 12V vehicle architectures. IC Role / Device Role / Timing Role: High-side power switch controlled via CAN-linked microcontroller GPIO with diagnostic feedback. Use Value: -40V VDSS withstands load-dump transients up to ISO 7637-2 Pulse 5a (±60V), eliminating need for external TVS clamping. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT4007LPS-13 | RDS(ON) = 3.2mΩ @ -10V but rated only to -30V VDSS; larger PowerDI5060 package (5.0 × 6.0 mm). | Not suitable for 40V systems or space-constrained designs; better for ultra-low-loss 24V applications with ample board area. | Select if VDSS margin >10V is unnecessary and lowest possible conduction loss dominates thermal budget. |
| SI7157DP-T1-GE3 | RDS(ON) = 32mΩ @ -4.5V; same PowerDI3333-8 package; lower ID rating (-25A) and EAS (42 mJ). | Adequate for <15A loads; insufficient for 49A-rated reverse-polarity protection or high-current buck outputs. | Choose when cost sensitivity outweighs peak current and avalanche robustness requirements. |
Compared with DMT4007LPS-13 and SI7157DP-T1-GE3, DMP4026SFVW-13 uniquely balances 40V rating, 49A current capacity, 45mΩ logic-level RDS(ON), and 109 mJ UIS in the smallest footprint - making it optimal for high-density 24–36V industrial and automotive power switches where both voltage margin and board area are constrained.

FAQ
What is the maximum safe operating junction temperature for DMP4026SFVW-13?
The absolute maximum junction temperature is +150°C, validated across all electrical parameters in the datasheet. Derating begins above +125°C ambient when mounted on FR-4 with 2 oz copper; thermal design must maintain TJ ≤ 150°C under worst-case power dissipation (PD = 3.3 W at TA = +25°C with thermal bias).
Does DMP4026SFVW-13 require a gate resistor for stability in switching applications?
Yes - a 10–22 Ω series gate resistor is recommended to dampen ringing caused by gate-drain capacitance (Crss = 182 pF) and PCB trace inductance. This prevents spurious turn-on during fast VDS transitions and ensures clean 4.3 ns turn-on delay and 23.9 ns fall time.
Can DMP4026SFVW-13 be used in parallel configurations?
Yes, but only with matched devices and symmetrical PCB layout: identical gate drive paths, equal source inductance, and shared thermal plane. The positive RDS(ON) temperature coefficient (1.8× increase from -55°C to +150°C) enables inherent current sharing, provided VGS is tightly regulated across all paralleled units.
Is DMP4026SFVW-13 qualified to AEC-Q101 for automotive use?
No - the datasheet explicitly states AEC-Q101 qualification requires special change control and PPAP capability, which must be requested separately. Standard DMP4026SFVW-13 is not automotive-qualified; Diodes offers AEC-Q101 variants under different part numbers (e.g., DMP4026SFVWQ-13) with full PPAP documentation.
