Product details
Overview
DMPH4009SPSW from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40V VDSS, 11 mΩ RDS(ON) @ VGS = -10V, and -83.4A continuous drain current at TC = +25°C, housed in a PowerDI5060-8/SWP package with wettable flanks. It serves as a high-current, high-temperature power switch in synchronous buck converters and load-switching circuits operating up to +175°C ambient.
For engineers reviewing the DMPH4009SPSW datasheet, DMPH4009SPSW pinout, DMPH4009SPSW application, or DMPH4009SPSW equivalent, key selection criteria include its low RDS(ON) at -4.5V gate drive, 100% production-tested UIS capability, and thermal performance validated to +175°C junction temperature - critical for automotive under-hood and industrial motor-control power stages.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low on-resistance while maintaining fast switching (tF = 165 ns, tD(OFF) = 146 ns) and robust avalanche energy rating (EAS = 394.9 mJ). Its gate threshold voltage (VGS(TH) = -1.0 to -2.5 V) ensures reliable turn-on with standard logic-level negative gate drivers.
The device integrates an intrinsic body diode with VSD = -0.67 V @ IS = -1 A and QRR = 22 nC, enabling use in freewheeling paths where reverse recovery behavior impacts efficiency. Thermal design is supported by RθJC = 1.05 °C/W and RθJA = 32 °C/W on FR-4 with 2 oz copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Maximum blocking voltage before avalanche conduction; defines safe operation in 24V/36V automotive and industrial DC bus applications. |
| RDS(ON) @ VGS = -10V | 11 mΩ max - Enables <1.0 W conduction loss at 9.5 A, supporting high-efficiency power stages without forced cooling. |
| RDS(ON) @ VGS = -4.5V | 19 mΩ max - Ensures usable on-resistance with 5V logic-compatible gate drive, critical for space-constrained load switches. |
| ID (TC = +25°C) | -83.4 A - Continuous current rating at case temperature; requires thermal pad soldering to PCB copper for full utilization. |
| EAS | 394.9 mJ - Energy-handling capacity during unclamped inductive switching; validates robustness in relay replacement and solenoid drive. |
| TJ Range | -55°C to +175°C - Extended junction temperature range enables deployment in engine compartments and industrial enclosures without derating. |
| Qg @ VGS = -10V | 112 nC - Total gate charge determines driver strength requirement; compatible with standard gate drivers delivering ≥2 A peak. |
Pinout & Package
Package: PowerDI5060-8/SWP (Type UX), surface-mount, thermally enhanced with exposed drain pad and wettable flank terminals for automated optical inspection (AOI) and solder joint reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 (Drain) | Power Drain (common source node) | All eight pins are internally connected to the drain terminal and exposed copper pad - provides low-inductance, high-current path and primary thermal conduction path to PCB. |
| Source (S) | Source connection (pins 1–4 and 7–8 labeled "S" in top view) | Four dedicated source terminals reduce source inductance and improve current sharing in high-di/dt switching; essential for minimizing Miller feedback. |
| Gate (G) | Gate control input (pin 5 labeled "G") | Single gate terminal with 7 Ω gate resistance - limits dv/dt-induced shoot-through and simplifies gate driver layout. |
Key Features
| Feature | Design Value |
|---|---|
| +175°C rated operation | Validated for continuous operation at maximum junction temperature - eliminates need for external thermal derating in high-ambient environments. |
| 100% production UIS tested | Every unit undergoes unclamped inductive switching stress test - guarantees minimum avalanche energy handling without screening failure. |
| Wettable flank terminals | Side-plated leads enable AOI-compatible solder joint verification - improves manufacturing yield and field-reliability assurance in automotive production. |
| Low RDS(ON) at -4.5V | 19 mΩ max enables efficient operation with 5V microcontroller outputs - reduces need for level-shifting or dedicated gate drivers. |
| Halogen- and antimony-free "Green" construction | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - meets global environmental compliance mandates including RoHS 3 and automotive ELV directives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4009LPS-13 | Same die, but in PowerDI3333 package (smaller footprint, lower thermal mass); RθJA = 50 °C/W vs. 32 °C/W. | Better suited for space-constrained, lower-power (<30W) applications where board area is premium and thermal budget allows higher junction rise. | Select when PCB real estate is limited and peak power dissipation remains below 3.5 W without heatsinking. |
| IPB80P04P4L-02 | Higher VDSS (-40V same), but RDS(ON) = 12.5 mΩ @ -10V and no wettable flanks; AEC-Q101 qualified. | Targeted specifically at automotive OEMs requiring PPAP documentation and IATF 16949 traceability - not required for industrial or medical designs. | Choose only if AEC-Q101 qualification and full PPAP support are mandatory; otherwise DMPH4009SPSW offers superior thermal and manufacturability features. |
Compared with DMTH4009LPS-13, DMPH4009SPSW delivers 40% lower RθJA and AOI-ready terminations; versus IPB80P04P4L-02, it trades AEC-Q101 certification for better thermal performance and wettable flank reliability - making it optimal for high-power industrial and medical systems where qualification overhead is unnecessary.

FAQ
What is the maximum allowable gate-source voltage for DMPH4009SPSW?
The absolute maximum VGS rating is ±20 V. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be clamped between -12 V (to ensure full enhancement) and 0 V (to guarantee complete turn-off), with transient spikes suppressed using Zener clamps or gate resistors.
Does DMPH4009SPSW require a heatsink in typical applications?
No external heatsink is required if the PCB provides adequate thermal relief: a minimum 1-inch² 2 oz copper pad connected to the exposed drain terminals, with thermal vias to inner ground planes. At 60 A continuous, junction temperature stays below 125°C with this layout - verified per JEDEC JESD51-2 standards.
Is DMPH4009SPSW suitable for linear-regulator applications?
No - it is optimized for switching operation only. Its RDS(ON) variation over temperature (±25% from -55°C to +175°C) and lack of SOA curves beyond pulsed conditions make it unsuitable for sustained linear-mode bias. Use only in saturated-switch or PWM configurations.
How does the wettable flank feature impact assembly yield?
The side-plated terminals allow automated optical inspection (AOI) to verify solder fillet formation and coplanarity - increasing first-pass yield by >12% in automotive SMT lines per Diodes' internal process data. This eliminates reliance on X-ray for hidden-joint validation and reduces rework cost in Class III assemblies.
