Product details
Overview
DMPH4026SFVW-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40V VDSS, 25 mΩ RDS(ON) @ VGS = -10V, and -52A continuous drain current at TC = +25°C, operating up to +175°C junction temperature. It is designed for reverse-polarity protection and high-efficiency DC-DC power management in space-constrained automotive and industrial systems.
For engineers reviewing the DMPH4026SFVW-7 datasheet, DMPH4026SFVW-7 pinout, DMPH4026SFVW-7 application, or DMPH4026SFVW-7 equivalent, this device's PowerDI3333-8 package, low RDS(ON) at 4.5V gate drive, 100% UIS-tested ruggedness, and thermal performance at elevated ambient temperatures are critical selection criteria.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low on-resistance while preserving fast switching characteristics. Its gate threshold voltage (VGS(TH) = -0.8 to -1.8 V) ensures reliable turn-on with standard logic-level drivers, and its body diode exhibits tRR = 17.3 ns and QRR = 8.7 nC under 100 A/µs dI/dt conditions.
The device features a thermally enhanced PowerDI3333-8 package with exposed drain pad, delivering RθJC = 1.25 °C/W and RθJA = 38.4 °C/W on 2 oz copper FR-4 - enabling high-power density without external heatsinking in compact board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Withstands up to -40V drain-source blocking voltage before avalanche conduction. |
| RDS(ON) | 25 mΩ max @ VGS = -10V, ID = -3A - Enables <1.3 W conduction loss at 52A, critical for thermal budget control. |
| ID (TC = 25°C) | -52 A - Supports high-current reverse-polarity protection paths without derating at case temperature. |
| TJ Range | -55°C to +175°C - Qualified for under-hood automotive and industrial environments where ambient exceeds 125°C. |
| Qg | 45.8 nC @ VGS = -10V - Determines gate driver strength requirement for <76 ns total switching time (td(on) + tr + td(off) + tf). |
| EAS | 109 mJ - Specifies single-pulse avalanche energy handling capability, supporting unclamped inductive load robustness. |
| Ciss | 2064 pF - Impacts high-frequency gate drive impedance and EMI generation in synchronous buck or OR-ing configurations. |
Pinout & Package
Package: PowerDI3333-8 (SWP), surface-mount, thermally enhanced with exposed drain pad. Dimensions: 3.30 mm × 3.30 mm × 0.80 mm (L × W × H); weight ≈ 0.03 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (Top-side D) | Drain | Four parallel drain terminals connected to internal die drain metallization and exposed bottom pad - primary heat path and high-current return node. |
| 5 (Top-side G) | Gate | Single gate input controlling channel conduction; requires ≤±20V gate-source voltage per rating. |
| 6, 7, 8 (Top-side S) | Source | Three parallel source terminals forming low-inductance source connection; referenced to system ground or input rail in high-side switch configurations. |
Key Features
| Feature | Design Value |
|---|---|
| +175°C rated operation | Enables deployment in engine bay, motor control, and industrial power supplies where ambient exceeds 125°C without thermal shutdown. |
| 25 mΩ RDS(ON) @ -10V | Reduces conduction loss by >40% vs. comparable SO-8 P-MOSFETs, directly improving efficiency in 12V/24V reverse-battery protection circuits. |
| PowerDI3333-8 footprint | Occupies only 33% board area of SO-8 - allows denser PCB layout in space-limited modules like automotive ECUs and PoE injectors. |
| 100% UIS tested | Guarantees avalanche ruggedness across production lot - eliminates need for external snubbers in inductive load switching applications. |
| Halogen- and antimony-free | Meets "Green" compliance (Br+Cl <1500 ppm, Sb <1000 ppm) required for EU automotive and industrial environmental certifications. |
Applications
| Automotive Reverse-Polarity Protection | Industrial DC-DC Converter High-Side Switch |
|---|---|
Use Scenario: Protects vehicle infotainment and ADAS ECUs from damage due to incorrect battery terminal connection during service or jump-starting. IC Role / Device Role / Timing Role: P-channel high-side switch placed between battery input and downstream power rail; operates in static on/off state with no PWM timing requirements. Use Value: Eliminates need for series diode drop (≥0.4V), preserving 12V system headroom and reducing heat dissipation by >80% vs. Schottky solutions. |
Use Scenario: Controls power delivery to isolated 5V/3.3V rails in programmable logic controllers and sensor hubs powered from 24V industrial buses. IC Role / Device Role / Timing Role: High-side load switch enabling controlled inrush current and hot-swap capability; driven by microcontroller GPIO with slow slew rate. Use Value: Leverages low RDS(ON) at 4.5V gate drive to maintain <15 mV dropout at 20A, ensuring stable downstream regulator input voltage. |
| Server OR-ing Diode Replacement | Motor Drive Power Stage Protection |
Use Scenario: Replaces discrete Schottky diodes in redundant 48V server power supply OR-ing circuits to reduce forward voltage drop and improve efficiency. IC Role / Device Role / Timing Role: Synchronous OR-ing FET used in back-to-back configuration; body diode conducts during dead-time, then channel conducts during active phase. Use Value: Achieves <0.05V effective forward drop at 30A (vs. 0.35V for Schottky), cutting conduction loss by ~85% and enabling higher power density. |
Use Scenario: Provides overvoltage and reverse-current protection for BLDC motor gate drivers and Hall sensor interfaces in HVAC blowers and pump controllers. IC Role / Device Role / Timing Role: Input-stage protection switch placed upstream of motor controller IC; activated only during fault conditions (e.g., battery reversal or regen surge). Use Value: Withstands 109 mJ avalanche energy and operates reliably at +150°C ambient - prevents latch-up or destruction during motor stall or short-circuit events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4007LPSQ-13 | Same -40V rating but 7.3 mΩ RDS(ON) @ -10V; larger PowerFLAT 5x6 package; AEC-Q101 qualified. | Targeted at automotive safety-critical systems requiring full qualification; not drop-in due to footprint and thermal pad layout differences. | Select when AEC-Q101 compliance and lower RDS(ON) justify larger board area and cost premium. |
| SI7157DP-T1-GE3 | 40V P-MOSFET in PowerPAK SO-8; 22 mΩ RDS(ON) @ -10V; RθJA = 50°C/W (higher thermal resistance). | Compatible with legacy SO-8 layouts but lacks +175°C rating and fails UIS testing per datasheet. | Choose only for cost-sensitive, non-automotive designs where ambient stays below 105°C and inductive stress is absent. |
Compared with DMTH4007LPSQ-13 and SI7157DP-T1-GE3, DMPH4026SFVW-7 uniquely balances ultra-compact PowerDI3333-8 size, +175°C operation, and production-tested UIS ruggedness - making it optimal for next-gen automotive and industrial power modules where space, temperature, and reliability are co-constrained.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMPH4026SFVW-7 supports -38A continuous drain current at TC = +100°C with VGS = -10V, as specified in the Absolute Maximum Ratings table. This derating reflects junction-to-case thermal resistance and safe operating area limits under steady-state conduction.
Does this MOSFET require a gate resistor for driving with a microcontroller GPIO?
A gate resistor is recommended to limit peak gate current and damp ringing, especially given its 45.8 nC total gate charge and 2.5 Ω intrinsic gate resistance. For 3.3V GPIO driving, a 10–22 Ω series resistor ensures controlled turn-on while avoiding excessive shoot-through risk in half-bridge configurations.
Can DMPH4026SFVW-7 be used in linear regulation mode?
No - this MOSFET is not characterized or rated for linear (ohmic) operation. Its Safe Operating Area (SOA) curve shows only pulsed operation above 10 µs, and thermal runaway risk is high under sustained VDS × ID > 2W conditions without active cooling. Use only in switching or saturated on/off modes.
Is the PowerDI3333-8 package compatible with standard reflow profiles?
Yes - the package meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for standard lead-free reflow profiles (peak 260°C). The matte tin finish on copper leadframe ensures solderability per MIL-STD-202, Method 208, and the UL 94V-0 molding compound withstands thermal cycling without delamination.
