Product details
Overview
DMPH4025SFVWQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40 V VDSS, 25 mΩ RDS(ON) @ VGS = -10 V, and -40 A continuous drain current at TC = +25°C. It is AEC-Q101 qualified, PPAP-capable, and housed in the thermally efficient PowerDI3333-8 package-designed specifically for automotive reverse-polarity protection and DC-DC converter power switches.
For engineers reviewing the DMPH4025SFVWQ-13 datasheet, DMPH4025SFVWQ-13 pinout, DMPH4025SFVWQ-13 application, or DMPH4025SFVWQ-13 equivalent, key selection criteria include its -40 V breakdown rating, low 25 mΩ on-resistance at -10 V gate drive, +175°C junction temperature capability, AEC-Q101 qualification status, and PowerDI3333-8 thermal performance in high-density automotive PCB layouts.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-temperature automotive environments. Its gate threshold voltage (VGS(TH)) ranges from -0.8 V to -1.8 V, enabling robust turn-on with standard -4.5 V or -10 V logic-level gate drivers.
The device integrates a body diode with -1 V forward voltage at -1 A and supports avalanche energy of 82 mJ (L = 0.3 mH). Thermal resistance is specified as RθJC = 2.5 °C/W and RθJA = 53 °C/W on FR-4 with 2 oz copper, confirming suitability for thermally constrained under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Withstands up to 40 V reverse drain-source voltage without breakdown in automotive battery systems. |
| RDS(ON) Max | 25 mΩ @ VGS = -10 V - Ensures ≤0.9 W conduction loss at -30 A, critical for high-efficiency power management. |
| ID Continuous | -40 A @ TC = +25°C - Supports high-current load switching in engine control units and ADAS modules. |
| Junction Temp | +175°C max - Enables reliable operation in under-hood ambient temperatures exceeding +125°C. |
| Qg Total | 38.6 nC @ VGS = -10 V - Determines gate driver strength requirement for <75 ns turn-off delay in 100 kHz+ converters. |
| Ciss | 1918 pF @ VDS = -20 V - Impacts high-frequency switching losses and EMI behavior in synchronous rectifier designs. |
| Avalanche Energy | 82 mJ (L = 0.3 mH) - Provides ruggedness against inductive load transients in motor drivers and solenoid controls. |

Use Scenario: Installed in-series with vehicle battery input to prevent damage during jump-start misconnection or battery reversal. IC Role / Device Role / Timing Role: High-side P-channel switch controlling main power rail entry; operates in linear or saturated mode depending on fault condition. Use Value: Withstands -40 V reverse bias and delivers <1.0 V drop at 30 A due to 25 mΩ RDS(ON), minimizing voltage loss and thermal stress. |
Use Scenario: Used as synchronous rectifier or high-side switch in 12 V → 5 V/3.3 V buck converters for infotainment and ADAS ECUs. IC Role / Device Role / Timing Role: Power-switching element operating at 200–500 kHz; body diode conducts during dead-time, requiring low VSD. Use Value: 82 mJ avalanche energy and -1 V VSD at -1 A ensure robustness against inductive kickback and reduce need for external snubbers. |
| Engine Control Unit Power Management | Body Control Module Load Switching |

Use Scenario: Controls power to fuel injectors, ignition coils, or sensors in engine bay environments where ambient reaches +125°C. IC Role / Device Role / Timing Role: High-current load switch activated via microcontroller GPIO; must survive repeated hot/cold cycling and vibration. Use Value: +175°C TJ rating and 2.5 °C/W RθJC allow direct mounting on thick copper layers, eliminating heatsinks in space-constrained ECU housings. |
Use Scenario: Drives door locks, window motors, or lighting loads in BCMs requiring precise current limiting and short-circuit protection. IC Role / Device Role / Timing Role: Low-side or high-side load switch with integrated thermal shutdown behavior governed by RDS(ON) temperature coefficient. Use Value: RDS(ON) increases only 1.6× from -55°C to +175°C (per Fig. 6), ensuring stable current-limiting behavior across full automotive temperature range. |
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 | RDS(ON) = 7.2 mΩ @ -10 V, but rated only to +150°C; larger PowerDI5060 package (5.0 × 6.0 mm). | Better conduction efficiency but unsuitable for >+150°C ambient zones like near exhaust manifolds. | Select when lower RDS(ON) outweighs size and temperature constraints. |
| DMT6009LPSQ-13 | RDS(ON) = 9.0 mΩ @ -10 V, +175°C rated, but uses larger PowerDI5060 package and has higher Qg (52 nC). | Higher gate charge increases driver complexity and switching loss in high-frequency DC-DC stages. | Prefer for ultra-low-loss linear regulation where gate drive overhead is acceptable. |
Compared with DMTH4007LPSQ-13 and DMT6009LPSQ-13, DMPH4025SFVWQ-13 uniquely balances 25 mΩ RDS(ON), +175°C rating, and minimal 3.3 mm × 3.3 mm footprint-making it optimal for space- and temperature-constrained automotive power switches where moderate conduction loss is acceptable.

FAQ
What is the maximum allowable gate-source voltage for DMPH4025SFVWQ-13?
The absolute maximum VGS is ±20 V per the datasheet's Maximum Ratings table. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be clamped to -12 V maximum in negative logic applications, with transient spikes limited by external Zener diodes if needed.
Does DMPH4025SFVWQ-13 require a gate resistor for automotive PWM switching?
Yes-a series gate resistor (typically 10–47 Ω) is recommended to damp ringing and limit peak gate current. With Qg = 38.6 nC and typical driver rise/fall times, uncontrolled gate drive can cause overshoot exceeding ±20 V or induce EMI in sensitive CAN/LIN networks.
How does the PowerDI3333-8 package improve thermal performance over SO-8?
PowerDI3333-8 reduces RθJC to 2.5 °C/W versus ~3.5–4.0 °C/W for SO-8 due to its exposed drain pad directly soldered to large PCB copper areas. This enables 60 W power dissipation at TC = +25°C-nearly double SO-8's capability-and lowers junction temperature by up to 25°C in identical layouts.
Is DMPH4025SFVWQ-13 compatible with lead-free reflow profiles?
Yes-it is fully RoHS 3 compliant and rated for moisture sensitivity level 1 per J-STD-020. The device supports standard Pb-free reflow profiles (peak 260°C, 30 sec max), with matte tin annealed terminals ensuring reliable solder wetting and intermetallic formation on OSP- or ENIG-finished PCBs.
