Product details
Overview
DMP4026SFVWQ-13 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) of 25 mΩ @ VGS = -10V and 45 mΩ @ VGS = -4.5V. It is AEC-Q101 qualified and designed for automotive reverse-polarity protection and DC-DC converter power switches.
For engineers reviewing the DMP4026SFVWQ-13 datasheet, DMP4026SFVWQ-13 pinout, DMP4026SFVWQ-13 application, or DMP4026SFVWQ-13 equivalent, key selection criteria include its thermally efficient PowerDI3333-8 footprint, -40V VDSS, 100% production-tested UIS capability, and IATF 16949-manufactured traceability for automotive-grade reliability.
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 -1.8 V) ensures robust turn-on with standard 5V/3.3V logic-level gate drivers under wide temperature range (-55°C to +150°C).
The device integrates a body diode with VSD = -0.7 to -1.0 V @ IS = -1A and tRR = 17.3 ns, enabling efficient synchronous rectification and reverse-current blocking in bidirectional power paths without external diodes.
Key Specifications

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) = 3.7 mΩ @ -10V (lower), but larger PowerDI5060 package (5.0 × 6.0 mm). | Better thermal performance for >60A continuous use; less suitable for ultra-compact layouts. | Select when higher current and lower conduction loss outweigh board-area constraints. |
| IPB40P04P4L-02 | TO-263-3 package, RDS(ON) = 4.0 mΩ @ -10V, no AEC-Q101 documentation publicly available. | Requires external heatsink; lacks PPAP documentation for Tier-1 automotive qualification. | Use only in non-safety-critical industrial applications where AEC-Q101 is not mandated. |
Compared with DMT4007LPSQ-13 and IPB40P04P4L-02, the DMP4026SFVWQ-13 uniquely balances AEC-Q101 compliance, 3.3 mm² footprint, and 45 mΩ RDS(ON) at 4.5V gate drive-making it optimal for space-limited automotive modules requiring guaranteed qualification and logic-level compatibility.

FAQ
What is the maximum allowable gate-source voltage for DMP4026SFVWQ-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 circuits should clamp VGS between -12 V (for fast turn-on) and 0 V (for turn-off), avoiding negative overshoot beyond -20 V during switching transients.
Does DMP4026SFVWQ-13 require a gate resistor for automotive applications?
Yes-a series gate resistor (typically 10–47 Ω) is recommended to dampen ringing caused by parasitic inductance in high-current automotive wiring harnesses. This prevents unintended turn-on due to dV/dt coupling and reduces EMI emissions during 100+ kHz switching in DC-DC converters.
How is thermal performance validated for DMP4026SFVWQ-13 in real PCB layouts?
Thermal resistance values are measured using JEDEC-standard test boards: RθJA = 38.4 °C/W on 2 oz FR-4 with 1-inch² bottom-layer copper, and RθJC = 1.25 °C/W to the exposed drain pad. Layouts must replicate the recommended pad dimensions (X3 = 2.600 mm, Y2 = 1.650 mm) to achieve these ratings.
Can DMP4026SFVWQ-13 be used in bidirectional current applications?
No-it is a unidirectional P-channel MOSFET. While its body diode conducts from source to drain (forward-biased when VSD > 0), the device cannot block voltage or conduct controlled current in the reverse direction. Bidirectional switching requires back-to-back MOSFET configurations or dedicated bidirectional switches.
