Product details

Overview

DMP4026LSD from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -40V V_DSS, 25 mΩ R_DS(ON) @ V_GS = -10V, and -6.5A continuous drain current at T_A = +25°C. It serves as a synchronous rectifier or high-side load switch in compact DC-DC converters and motor control H-bridges.

For engineers reviewing the DMP4026LSD datasheet, DMP4026LSD pinout, DMP4026LSD application, or DMP4026LSD equivalent, key selection criteria include its dual P-channel topology, low R_DS(ON) at -4.5V gate drive, SO-8 thermal performance (R_θJA = 73.1°C/W with 1-inch² copper), and AEC-Q101 readiness for automotive-grade power stages.

Technical Context

This device integrates two identical P-channel MOSFETs in a single SO-8 package, sharing common source terminals per channel and enabling independent gate control. Its -1.8V maximum V_GS(TH) ensures reliable turn-on with standard logic-level drivers, while 18.3 mΩ typical R_DS(ON) @ -4.5V supports efficient operation in 5V-input buck regulators.

The MOSFET features 62 mJ avalanche energy rating (L = 0.3 mH) and 100% production-tested UIS capability, confirming robustness against inductive switching transients in printer head drivers and backlight LED current sinks.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual P-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMC2038LVT-7	Single P-channel, 20V, 19mΩ @ -4.5V, SOT-26 package	Lacks dual configuration; requires two devices for same functionality	Select when board space permits discrete placement and thermal isolation is preferred
SI7851DP-T1-GE3	Dual P-channel, 40V, 32mΩ @ -4.5V, SO-8, higher Q_G (60nC)	Slower switching (t_F = 32ns) increases switching loss in >300kHz designs	Choose when lower cost outweighs 12% efficiency penalty in 100–200kHz industrial supplies

Compared with DMC2038LVT-7 and SI7851DP-T1-GE3, DMP4026LSD uniquely delivers dual-channel integration with lowest R_DS(ON) at -4.5V in SO-8, enabling compact, high-efficiency 24V power stages without sacrificing avalanche ruggedness.

FAQ

What is the maximum continuous drain current for each channel at 70°C ambient?

Each channel supports -5.2 A continuous drain current at T_A = +70°C with SO-8 mounting on FR-4 PCB using minimum recommended pad layout. This rating assumes no derating from junction temperature limits and accounts for thermal resistance of 96.4°C/W in standard layout.

Does DMP4026LSD support 3.3V gate drive?

No - the gate threshold voltage range is -0.8 V to -1.8 V, but R_DS(ON) rises sharply below -4.5 V. At V_GS = -3.3 V, typical R_DS(ON) exceeds 100 mΩ, increasing conduction loss by >3× versus -4.5 V drive; use only with ≥4.5 V gate swing.

How is the SO-8 package thermally optimized for dual-channel operation?

The SO-8 footprint uses shared source pins (1–3 and 6–8) to minimize internal thermal coupling between channels, while the 73.1°C/W R_θJA rating with 1-inch² copper plate confirms effective heat spreading across both channels under simultaneous full-load operation.

Is DMP4026LSD qualified for automotive applications?

Yes - it is AEC-Q101 qualified and manufactured in IATF 16949-certified facilities. While not pre-qualified for PPAP, Diodes provides full change control documentation and automotive-grade traceability upon request for Tier-1 supply chain integration.
