Product details
Overview
DMPH4026SFVW-13 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, housed in a thermally efficient PowerDI3333-8 package. It delivers high-current reverse-polarity protection and power-management switching in space-constrained DC-DC converters.
For engineers reviewing the DMPH4026SFVW-13 datasheet, DMPH4026SFVW-13 pinout, DMPH4026SFVW-13 application, or DMPH4026SFVW-13 equivalent, key selection criteria include its -175°C maximum junction temperature rating, low RDS(ON) at 4.5 V gate drive, 100% UIS-tested ruggedness, and 33% board-area reduction versus SO-8.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low on-resistance while maintaining fast switching performance (tF = 23.9 ns, tD(OFF) = 71.8 ns) and robust avalanche capability (EAS = 109 mJ). Its gate threshold voltage range of -0.8 V to -1.8 V ensures reliable turn-on with standard logic-level negative gate drivers.
The device features a fully rated body diode with VSD = 0.7–1.0 V at -1 A and tRR = 17.3 ns, enabling synchronous rectification and bidirectional current handling in compact power stages. Thermal design is supported by RθJC = 1.25 °C/W and RθJA = 38.4 °C/W on a 2 oz copper FR-4 board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Withstands up to 40 V reverse drain-source voltage without breakdown |
| RDS(ON) | 25 mΩ @ VGS = -10 V - Enables <1.3 W conduction loss at 52 A continuous current |
| ID (max) | -52 A @ TC = +25°C - Supports high-current load switching with external heatsinking |

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 PowerDI3333-8 package but -40 V/7.2 mΩ @ -10 V; higher cost; AEC-Q101 qualified | Required for automotive safety-critical systems where qualification is mandatory | Select when ISO 26262 ASIL-B compliance is required; otherwise DMPH4026SFVW-13 offers better cost/performance balance |
| SI7157DP-T1-GE3 | SO-8 package; -40 V/28 mΩ @ -10 V; RθJA = 62 °C/W; no UIS rating | Suitable for non-ruggedized consumer applications with lower thermal constraints | Choose only if legacy SO-8 footprint must be retained; avoid in high-temp or inductive-load designs |
Compared with DMTH4007LPSQ-13, DMPH4026SFVW-13 trades 17 mΩ higher RDS(ON) for 30% lower unit cost and identical thermal metrics; versus SI7157DP-T1-GE3, it delivers 2.3× better thermal resistance and guaranteed UIS ruggedness at minimal board area penalty.

FAQ
What is the maximum gate-source voltage rating for DMPH4026SFVW-13?
The absolute maximum VGS rating is ±20 V. Exceeding this value risks permanent gate oxide damage. For reliable operation, gate drive circuits must clamp VGS between -20 V and +20 V, with recommended operating range of -10 V to 0 V for full enhancement and safe turn-off.
Does DMPH4026SFVW-13 require a gate resistor for EMI suppression?
Yes - a 10 Ω to 47 Ω series gate resistor is recommended to dampen ringing caused by gate-drain capacitance (Crss = 183 pF) interacting with PCB trace inductance. This reduces electromagnetic emissions during 71.8 ns turn-off delay and improves switching waveform fidelity in 200–500 kHz DC-DC applications.
Can DMPH4026SFVW-13 be used in parallel configurations?
Yes - its positive temperature coefficient of RDS(ON) (normalized resistance increases with TJ) enables stable current sharing. Parallel operation requires matched gate drive paths, symmetrical PCB layout, and thermal coupling via shared copper pour to ensure <5°C inter-device junction temperature delta at full load.
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, 60 sec max above 217°C). The matte tin finish ensures solderability per MIL-STD-202, Method 208, and the 0.03 g mass supports uniform thermal ramp rates.
