Product details

Overview

DMP4009SSSQ from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in SO-8 package, rated for -10A continuous drain current at V_GS = -10V, with R_DS(ON) = 11 mΩ (max), AEC-Q101 qualified, and optimized for high-efficiency DC-DC converters and power-management functions in automotive and industrial systems.

For engineers reviewing the DMP4009SSSQ datasheet, DMP4009SSSQ pinout, DMP4009SSSQ application, or DMP4009SSSQ equivalent, this page delivers verified electrical parameters, thermal performance data, SO-8 terminal mapping, AEC-Q101 compliance status, and validated alternative parts for automotive-grade power switching design.

Technical Context

This MOSFET operates as a low-side synchronous rectifier or high-side load switch in buck converters and power-distribution circuits. Its -40V V_DSS, -2.5V maximum V_GS(TH), and 53 nC total gate charge at V_GS = -4.5V support robust turn-on under 5V logic control while maintaining fast switching transitions (t_r = 41 ns, t_f = 165 ns).

The device features integrated body diode with V_SD = -0.7V at -1A, 330 mJ avalanche energy rating (E_AS), and 100% production-tested UIS capability-enabling reliable operation in inductive load switching and fault-tolerant power rails.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-40 V - Withstands up to 40V reverse drain-source voltage without breakdown, suitable for 24V automotive bus and 36V industrial input stages.
R_DS(ON)	11 mΩ max @ V_GS = -10V - Enables <100 mW conduction loss at 10A, critical for thermally constrained PCB layouts.
I_D (continuous)	-10 A @ T_A = +25°C - Supports high-current power delivery in compact SO-8 footprint with 2.1 W power dissipation on FR-4 board.
Q_g	53 nC @ V_GS = -4.5V - Matches standard 5V gate drivers; enables efficient switching at >500 kHz in synchronous buck topologies.
E_AS	330 mJ - Sustains single-pulse inductive energy without failure, eliminating need for external snubbers in relay/actuator drive circuits.
T_J range	-55°C to +150°C - Qualified for under-hood automotive environments and extended-temperature industrial control modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT4009LPS-13	Same R_DS(ON) (11 mΩ @ -10V), but in PowerDI5060 package with lower R_θJA (50°C/W vs. 58.5°C/W); no AEC-Q101 qualification.	Preferred for higher-power density industrial SMPS where automotive qualification is not required.	Select when thermal performance outweighs automotive compliance and SO-8 footprint is not mandatory.
IPD250N04LG	Higher V_DSS (-40V same), but R_DS(ON) = 2.5 mΩ @ -10V and Q_g = 105 nC; AEC-Q101 qualified, TO-252 package.	Suitable for ultra-low-loss 12V/24V high-current switches where gate drive strength permits higher Q_g.	Choose for <5 mΩ conduction loss needs and TO-252 mounting flexibility, accepting larger footprint and higher gate drive demand.

Compared with DMT4009LPS-13 and IPD250N04LG, the DMP4009SSSQ uniquely balances SO-8 manufacturability, AEC-Q101 compliance, and 11 mΩ R_DS(ON)-making it optimal for cost-sensitive, space-constrained automotive modules requiring zero-change qualification.

FAQ

Is DMP4009SSSQ suitable for high-side switching with 5V gate drive?

Yes. With V_GS(TH) ranging from -1.0V to -2.5V and R_DS(ON) = 19 mΩ at V_GS = -4.5V, it fully enhances using standard 5V logic-level gate drivers. The -4.5V gate voltage yields -8A continuous current, sufficient for most automotive load-switching applications.

What is the thermal resistance of DMP4009SSSQ on a standard FR-4 PCB?

When mounted on an FR-4 board with 2 oz copper and minimum recommended pad layout, R_θJA is 79°C/W. With enhanced 1-inch square copper pour, R_θJA improves to 58.5°C/W, enabling 2.1 W power dissipation at T_A = +70°C without exceeding T_J = +150°C.

Does DMP4009SSSQ include integrated ESD protection?

No. The datasheet does not specify on-chip ESD protection structures. External TVS diodes or series resistors are recommended for gate protection in environments with >2 kV HBM risk, especially in automotive assembly lines or field-replaceable modules.

Can DMP4009SSSQ replace N-channel MOSFETs in existing designs?

No-it is a P-channel device and requires inverted gate drive logic (low-side driver or level-shifter for high-side use). Direct substitution would require redesigning gate control circuitry and verifying voltage margin, as its V_DSS is -40V versus typical N-channel +40V ratings.
