Product details
Overview
DMPH4009SSS from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40V VDSS, 11 mΩ RDS(ON) at VGS = -10V, and -11A continuous drain current at TA = +25°C, operating up to +175°C junction temperature. It serves as a high-efficiency power switch in synchronous buck converters and load-switching circuits where low conduction loss and robust thermal performance are critical.
For engineers reviewing the DMPH4009SSS datasheet, DMPH4009SSS pinout, DMPH4009SSS application, or DMPH4009SSS equivalent, key selection criteria include its 175°C rating, SO-8 package thermal resistance (RθJA = 58.5°C/W with copper pad), 100% UIS-tested ruggedness, and gate charge profile optimized for fast switching in DC-DC power stages.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining controlled Qg (112 nC at VGS = -10V) and low Ciss (5697 pF), enabling efficient operation in high-frequency synchronous rectification. Its body diode exhibits tRR = 27 ns and QRR = 22 nC under IF = -9.8A, supporting hard-switched topologies.
The device is characterized across -55°C to +175°C, with RDS(ON) normalized to 1.9× at TJ = 175°C (VGS = -10V), and VGS(TH) stable between -1.0 V and -2.5 V. It meets AEC-Q101 stress-test requirements when qualified per customer request.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Maximum blocking voltage before avalanche onset; defines safe operation in 36V automotive or 24V industrial bus applications. |
| RDS(ON) | 11 mΩ @ VGS = -10V - Enables ≤1.2 W conduction loss at -9.8A, reducing thermal load in compact power stages. |
| ID (continuous) | -11 A @ TA = +25°C - Supports high-current load switching on FR-4 PCBs with 1-inch² copper pad (PD = 2.5 W). |
| Qg | 112 nC @ VGS = -10V - Determines gate drive energy requirement; enables <150 ns total switching time with 2Ω driver. |
| TJ max | +175°C - Allows operation in under-hood automotive or high-ambient industrial environments without derating. |
| Ciss | 5697 pF @ VDS = -20V - Impacts Miller effect and gate drive stability; low Crss (408 pF) reduces turn-off sensitivity to dV/dt. |
| EAS | 330 mJ - Confirmed unclamped inductive switching capability supports reliable operation in flyback or boost converter primary switches. |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin small-outline). Molded plastic body with matte tin-annealed terminals; UL 94V-0 rated, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Common source connection; pins 1–4 internally bonded together for low-inductance, high-current return path. |
| 5, 6, 7, 8 | Drain (D) | Power output node; pins 5–8 tied to exposed drain paddle for enhanced thermal dissipation and current handling. |
| G | Gate (G) | Control input; requires -10V to fully enhance; threshold range (-1.0 V to -2.5 V) ensures reliable turn-on with standard logic-level drivers. |
Key Features
| Feature | Design Value |
|---|---|
| +175°C rated operation | Enables deployment in engine control units, motor drives, and industrial power supplies without external heatsinking. |
| 100% UIS tested | Guarantees survival under worst-case inductive turn-off transients (IAS = -25.7 A, L = 1 mH), eliminating need for external snubbers. |
| Low RDS(ON) × Qg figure-of-merit | 1232 Ω·nC - Balances conduction and switching losses for optimal efficiency in 300–1000 kHz DC-DC converters. |
| Halogen- and antimony-free "Green" construction | Meets RoHS 3 (2015/863/EU) with Br+Cl <1500 ppm and Sb <1000 ppm; suitable for automotive and medical end equipment. |
| SO-8 with exposed drain paddle | Thermal resistance reduced to RθJA = 58.5°C/W (vs. 79°C/W on minimal pad), improving power density by >30%. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4009LSD-13 | Same RDS(ON) (11 mΩ @ -10V) but in PowerDI 5060-8 package; RθJA = 40°C/W, higher current rating (-13A). | Better thermal performance in space-constrained layouts; requires different PCB footprint and reflow profile. | Select for higher-power designs needing lower thermal resistance; not drop-in compatible due to package mismatch. |
| SI7157DP-T1-GE3 | Higher RDS(ON) (15 mΩ @ -10V); lower Qg (70 nC); same SO-8 package and -40V rating. | Optimized for ultra-fast switching (>1 MHz) rather than lowest conduction loss; less suited for high-current DC-DC outputs. | Prefer when switching frequency exceeds 500 kHz and gate drive strength is limited; verify thermal margin at full load. |
Compared with DMTH4009LSD-13 and SI7157DP-T1-GE3, DMPH4009SSS delivers the best balance of low RDS(ON), SO-8 compatibility, and 175°C operation-making it optimal for thermally demanding, medium-frequency power switches where board layout reuse is essential.

FAQ
What is the maximum continuous drain current at 100°C ambient?
At TA = +100°C, the DMPH4009SSS supports -7.5 A continuous drain current when mounted on an FR-4 board with minimum recommended pad layout (RθJA = 79°C/W). Derating follows the thermal curve in Figure 12 of DS45502 Rev. 2–2.
Is the DMPH4009SSS qualified to AEC-Q101?
The DMPH4009SSS is designed to meet AEC-Q101 requirements and can be qualified per customer request. Diodes offers PPAP-capable manufacturing in IATF 16949-certified facilities, though standard commercial-grade parts require explicit qualification engagement.
What is the gate threshold voltage range and its variation with temperature?
VGS(TH) ranges from -1.0 V to -2.5 V at TA = +25°C (ID = -250 μA). As shown in Figure 8, it decreases slightly with rising junction temperature, remaining within -0.7 V to -2.2 V across -55°C to +175°C.
Can this MOSFET replace an N-channel device in high-side switching?
Yes-the DMPH4009SSS is a P-channel MOSFET designed for high-side switching without level-shifting circuitry. Its -10V gate drive requirement allows direct interface with 3.3V/5V microcontrollers using simple pull-up resistors, unlike N-channel alternatives requiring bootstrap or charge-pump drivers.
