Product details
Overview
DMP4026SFGQ-7 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for -28A continuous drain current at TC = +25°C, with RDS(ON) = 25 mΩ @ VGS = -10V and 45 mΩ @ VGS = -4.5V. It is AEC-Q101 qualified and PPAP-capable, designed for automotive motor controls, DC-DC converters, backlighting, and printer equipment.
For engineers reviewing the DMP4026SFGQ-7 datasheet, DMP4026SFGQ-7 pinout, DMP4026SFGQ-7 application, or DMP4026SFGQ-7 equivalent, key selection criteria include its low RDS(ON) at 4.5V gate drive, 100% production-tested UIS capability, thermal resistance of 3.8°C/W (junction-to-case), and IATF 16949-certified manufacturing.
Technical Context
This P-channel MOSFET operates as a high-side switch in automotive power management systems, supporting logic-level gate drive down to -4.5V. Its -40V VDSS, -1.8V maximum VGS(TH), and 2.3Ω gate resistance enable fast turn-on/turn-off with controlled dV/dt and minimal switching loss.
The device integrates a robust body diode with tRR = 18.5 ns and QRR = 9.5 nC under 100 A/µs di/dt, suitable for synchronous rectification and bidirectional current paths. Thermal design is supported by an exposed drain pad and RθJC = 3.8°C/W for direct heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Maximum drain-source blocking voltage for 12V/24V automotive rail protection |
| RDS(ON) @ VGS = -10V | 25 mΩ - Enables ≤0.7 W conduction loss at -28A, critical for high-current load switches |
| RDS(ON) @ VGS = -4.5V | 45 mΩ - Supports direct microcontroller GPIO drive without level-shifting in low-voltage control |
| Qg @ VGS = -10V | 48 nC - Determines gate driver power requirement and switching speed in PWM applications |
| trr / Qrr | 18.5 ns / 9.5 nC - Minimizes reverse recovery loss in flyback and buck-boost topologies |
| RθJC | 3.8°C/W - Allows direct thermal coupling to PCB copper or heatsink for sustained 33W power dissipation |
| EAS | 65 mJ - Withstands inductive energy spikes in motor drive and solenoid control without failure |
Pinout & Package
Package: PowerDI3333-8 - surface-mount, thermally enhanced 8-pin package with exposed drain pad (pins 1–4 and 6–8 are source; pin 5 is gate; drain connected to underside thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 6, 7, 8 | Source | Common source connection; multiple pins reduce bondwire inductance and improve current sharing |
| 5 | Gate | Single-point gate input; low 2.3Ω Rg supports clean edge control and EMI reduction |
| Bottom Pad | Drain | Exposed metal pad electrically and thermally connected to drain; requires solder mask defined stencil for reliable thermal transfer |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested in production | Guarantees ruggedness against unclamped inductive transients up to 20A and 65mJ without derating |
| AEC-Q101 qualification & PPAP support | Validated for automotive use with full change control, traceability, and IATF 16949 manufacturing compliance |
| Green, halogen-free construction | Meets <900 ppm Br/Cl and <1000 ppm Sb; UL 94V-0 rated molding compound for safety-critical assemblies |
| Low RDS(ON) at VGS = -4.5V | Enables direct interface with 5V/3.3V logic controllers-no external level shifter required in most automotive modules |

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 |
|---|---|---|---|
| DMT4006LPSQ-13 | RDS(ON) = 3.8 mΩ @ -10V (lower), but 5x larger package (SO-8); no AEC-Q101 certification | Not approved for automotive production; limited to industrial/commercial designs | Select only if higher current density and non-automotive qualification are acceptable |
| IPD450P04P4L-1R | RDS(ON) = 4.5 mΩ @ -10V; TO-252 package; AEC-Q101 qualified but lacks PPAP documentation | Requires larger PCB footprint and less thermal efficiency than PowerDI3333-8 | Prefer when lower RDS(ON) outweighs board space constraints and PPAP is not mandatory |
Compared with DMT4006LPSQ-13 and IPD450P04P4L-1R, the DMP4026SFGQ-7 uniquely balances AEC-Q101 qualification, PPAP readiness, compact PowerDI3333-8 footprint, and verified 4.5V drive capability-making it optimal for space-constrained, safety-compliant automotive modules.

FAQ
What is the maximum continuous drain current at 70°C case temperature?
The DMP4026SFGQ-7 supports -22A continuous drain current at TC = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by junction-to-case resistance (3.8°C/W) and ambient heat dissipation constraints on the PCB layout.
Is the body diode suitable for synchronous rectification in buck converters?
Yes-the body diode has tRR = 18.5 ns and QRR = 9.5 nC under 100 A/µs di/dt, enabling efficient synchronous rectification in 300–500 kHz buck converters. Its low VSD (-0.7 V typ. at -1A) further reduces conduction loss versus external Schottky diodes.
Does the PowerDI3333-8 package require special PCB layout considerations?
Yes-the exposed drain pad must be connected to a minimum 1-inch² copper pour with ≥4 thermal vias (0.3 mm diameter) to a solid inner ground plane. The recommended pad layout (X3 = 2.37 mm, Y3 = 3.70 mm) is published in Diodes' package outline document DS44883.
How does the gate threshold voltage vary over temperature?
VGS(TH) shifts from -0.8 V (min) at -55°C to -1.8 V (max) at +150°C, with typical variation centered near -1.3 V. Figure 8 in DS44883 shows monotonic negative drift, ensuring predictable turn-on behavior across the full -55°C to +150°C operating range.
