Product details
Overview
DMP4026SFVWQ-7 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) = 25 mΩ @ VGS = -10V and AEC-Q101 qualified for automotive reverse-polarity protection and DC-DC converter power switches.
For engineers reviewing the DMP4026SFVWQ-7 datasheet, DMP4026SFVWQ-7 pinout, DMP4026SFVWQ-7 application, or DMP4026SFVWQ-7 equivalent, key selection criteria include its -40V VDSS, thermally efficient PowerDI3333-8 footprint, 1.25°C/W RθJC, AEC-Q101 qualification, and 100% production-tested UIS capability.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-density automotive power rails. Its gate threshold voltage (VGS(TH) = -0.8 to -1.8V) enables robust turn-on with standard 5V or 3.3V logic-level gate drivers in high-side configurations.
The device integrates a body diode with tRR = 17.3 ns and QRR = 8.7 nC under 100 A/µs dI/dt, supporting synchronous rectification and bidirectional current handling in buck converters and load switches without external freewheeling diodes.

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 |
|---|---|---|---|
| DMT4007LPSQ-13 | RDS(ON) = 3.2 mΩ @ -10V (lower), but SO-8 package (larger footprint, higher RθJA) | Better conduction efficiency but requires more PCB area and less thermal margin in confined ECUs | Select when board space permits and lowest RDS(ON) dominates over thermal density |
| IPB40P04P4L-04 | TO-263-3 package, RDS(ON) = 4.0 mΩ @ -10V, higher ID = -120A, but no AEC-Q101 certification | Suitable for industrial motor drives but not approved for automotive safety-critical use | Select only for non-automotive applications where AEC-Q101 is not mandated |
Compared with DMT4007LPSQ-13 and IPB40P04P4L-04, the DMP4026SFVWQ-7 uniquely balances AEC-Q101 compliance, ultra-compact PowerDI3333-8 packaging, and production-validated UIS robustness-making it optimal for space-constrained, safety-certified automotive power stages where thermal density and reliability are co-prioritized.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMP4026SFVWQ-7 supports -39A continuous drain current at TC = +70°C per datasheet Table "Maximum Ratings". At TC = +100°C, derating applies: using RθJC = 1.25°C/W and TJ(max) = 150°C, maximum allowable power is 62.5W, yielding ~50A theoretical limit-but the safe operational limit remains -39A as specified for TC ≤ +70°C. No rating is provided beyond +70°C case temperature.
Is the PowerDI3333-8 package lead-free and RoHS compliant?
Yes. The DMP4026SFVWQ-7 uses matte tin annealed over copper leadframe and green molding compound meeting RoHS 3 (2015/863/EU), with <900 ppm bromine, <900 ppm chlorine, and <1000 ppm antimony. It is fully lead-free with no purposely added lead and certified to UL 94V-0 flammability rating.
Does this MOSFET require a gate resistor for automotive 12V applications?
A gate resistor is recommended to control dV/dt and prevent oscillation, especially in high-noise automotive environments. With Qg = 45.8 nC and typical gate driver output impedance of 1–5 Ω, a 10–22 Ω series resistor limits peak gate current to <1A and ensures clean turn-on/turn-off transitions without ringing, as verified in Diodes' application note AP02011.
Can the DMP4026SFVWQ-7 be used in parallel configurations?
Yes-its negative temperature coefficient of RDS(ON) (normalized RDS(ON) increases with temperature, Figure 6) enables inherent current sharing. Parallel operation is validated in Diodes' AN-2017-02, recommending matched layout symmetry, individual gate resistors, and shared source Kelvin connection to minimize imbalance under transient loads up to 100A total.
