Product details
Overview
DMPH4026SFVWQ-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40 V VDSS, 25 mΩ RDS(ON) at VGS = -10 V, and -52 A continuous drain current at TC = +25°C. It operates up to +175°C junction temperature and is housed in the thermally efficient PowerDI3333-8 package. This device serves as a high-reliability reverse-polarity protection switch in automotive power distribution modules.
For engineers reviewing the DMPH4026SFVWQ-7 datasheet, DMPH4026SFVWQ-7 pinout, DMPH4026SFVWQ-7 application, or DMPH4026SFVWQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, low RDS(ON) at 4.5 V gate drive, 100% UIS-tested ruggedness, and thermal performance in compact board space-constrained automotive ECUs.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low on-resistance 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 5 V or 3.3 V logic-level controllers.
The device integrates a body diode with 17.3 ns reverse recovery time and 8.7 nC QRR, supporting synchronous rectification in DC-DC converters. Its Ciss of 2064 pF and Qg of 45.8 nC at VGS = -10 V indicate moderate drive strength requirements for gate drivers in 12 V/24 V battery systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4007LPSQ-13 | Lower RDS(ON) (1.8 mΩ @ -10 V) but larger PowerDI5060 package; higher Qg (120 nC) | Better for ultra-low-loss high-current (>100 A) applications where board area is secondary | Select when thermal budget permits larger footprint and gate drive capability supports higher Qg |
| IPD250N04LGATMA1 | Same VDSS (-40 V), but N-channel; requires high-side gate driver; RDS(ON) = 2.5 mΩ @ -10 V | Suitable only where active high-side control with bootstrap or isolated driver is acceptable | Choose only if system already uses N-channel high-side architecture and can accommodate added driver complexity |
Compared with DMTH4007LPSQ-13 and IPD250N04LGATMA1, DMPH4026SFVWQ-7 delivers optimal balance of compact size, gate-drive simplicity, and thermal resilience for space-constrained automotive reverse-protection and load-switching functions without requiring external driver circuitry.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMPH4026SFVWQ-7 supports -38 A continuous drain current at TC = +100°C, verified per the datasheet's maximum ratings table. This derating reflects thermal limitations of the PowerDI3333-8 package under sustained high-power operation without forced cooling.
Does this MOSFET require a gate resistor for automotive EMI compliance?
A 10 Ω to 22 Ω gate resistor is recommended to dampen ringing caused by the 2.5 Ω intrinsic gate resistance and 2064 pF Ciss, especially in 12 V battery systems with long trace lengths. This reduces dv/dt-induced noise and meets CISPR 25 Class 5 emission limits in ECU designs.
Can the exposed drain pad be connected to PCB ground for thermal relief?
No - the exposed drain pad is electrically connected to the MOSFET's drain terminal and must be routed to the high-side power net. Connecting it to ground creates a short circuit. Thermal relief is achieved by soldering it to a large copper pour tied to the drain net, not ground.
Is the body diode suitable for freewheeling in inductive loads?
Yes - the body diode has a typical forward voltage of -0.7 V at -1 A and 17.3 ns reverse recovery time, making it suitable for freewheeling in 12 V automotive solenoids and relays. However, for high-frequency (>100 kHz) or high-current (>20 A) applications, an external Schottky may be preferred to minimize QRR-related losses.
