Product details
Overview
DMP4009SSS from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in SO-8 package, rated for -10A continuous drain current at VGS = -10V, with RDS(ON) = 11 mΩ (max), optimized for high-efficiency DC-DC converters and power-management functions where low conduction loss and fast switching are critical.
For engineers reviewing the DMP4009SSS datasheet, DMP4009SSS pinout, DMP4009SSS application, or DMP4009SSS equivalent, this device is selected for its verified -40V VDSS, 100% production-tested UIS capability, low Ciss (5697 pF), and AEC-Q101-qualified automotive readiness under IATF 16949 manufacturing.
Technical Context
This MOSFET operates as a high-side switch in synchronous buck converters and load-switching circuits, leveraging its negative gate threshold (-1.0 to -2.5 V) and low RDS(ON) to minimize conduction losses at 12V–24V input rails. Its body diode exhibits VSD = -0.7 V (typ) at -1 A, supporting efficient freewheeling in non-synchronous topologies.
The device features fully characterized dynamic parameters: Qg = 112 nC at VGS = -10V, tD(OFF) = 146 ns, and EAS = 330 mJ, enabling robust operation in hard-switched and inductive-load applications without external snubbing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Maximum blocking voltage for 24V automotive and industrial rail protection |
| RDS(ON) @ VGS = -10V | 11 mΩ max - Enables ≤110 mW conduction loss at -10A, critical for thermal budget in compact DC-DC designs |
| ID (continuous) | -10 A @ TA = +25°C - Supports high-current load switching on FR-4 PCBs with minimum pad layout |
| Ciss | 5697 pF - Low input capacitance reduces gate drive power and improves switching speed in high-frequency converters |
| EAS | 330 mJ - Confirmed avalanche energy rating ensures reliability during inductive turn-off transients |
| TJ range | -55°C to +150°C - Validated operation across automotive under-hood and industrial ambient conditions |
Pinout & Package
Package: SO-8 (Surface-mount, 8-pin small-outline integrated circuit), molded green plastic, UL 94V-0 rated, moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Common source connection for P-channel operation; internally paralleled pins reduce resistance and improve current sharing |
| 5, 6, 7, 8 | Drain (D) | High-current drain terminals; exposed drain paddle (pin 8 bottom side) enhances thermal dissipation to PCB copper |
| Gate (G) | Control terminal | Pin 3 (per top-view marking diagram) - accepts negative VGS to enhance channel; requires <±20V absolute max rating compliance |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested | Every unit validated for unclamped inductive switching up to 25.7A/330mJ - eliminates need for external avalanche derating |
| Low RDS(ON) @ -4.5V | 19 mΩ max enables logic-level gate drive compatibility with 5V microcontrollers and PMICs |
| Green compound & RoHS3 | Halogen-free (<900 ppm Br+Cl), antimony-free, lead-free - meets automotive and industrial environmental compliance mandates |
| Thermal performance | RθJA = 58.5°C/W with 1-inch² copper plate - supports >2W continuous dissipation in thermally enhanced layouts |
Applications
| Automotive Body Control Module | Industrial 24V Load Switch |
|---|---|
Use Scenario: High-side power distribution for door locks, lighting, and HVAC actuators in 12V/24V vehicle systems. IC Role / Device Role / Timing Role: P-channel MOSFET used as controlled high-side switch with reverse-polarity protection and inrush limiting. Use Value: -40V VDSS withstands load-dump transients up to ISO 7637-2 Pulse 5a; 100% UIS testing ensures survival during motor stall events. |
Use Scenario: Remote-controlled power enable for PLC I/O modules, sensors, and solenoids in factory automation. IC Role / Device Role / Timing Role: Solid-state replacement for mechanical relays, driven by isolated GPIO or optocoupler outputs. Use Value: 11 mΩ RDS(ON) limits self-heating to <1.1 W at 10A, eliminating heatsink requirements in DIN-rail enclosures. |
| Point-of-Load DC-DC Converter | USB-C Power Delivery Sink |
Use Scenario: Synchronous rectification in 5V–12V buck converters powering FPGAs, ASICs, and memory subsystems. IC Role / Device Role / Timing Role: Low-side synchronous rectifier (with external high-side driver) or high-side switch in non-synchronous topology. Use Value: 5697 pF Ciss and 112 nC Qg support 500 kHz–1 MHz switching with minimal gate drive loss and EMI. |
Use Scenario: Input power path control for USB-C PD sink devices requiring overvoltage and reverse-current protection. IC Role / Device Role / Timing Role: Reverse-polarity and overvoltage protection switch placed between connector and PD controller. Use Value: -40V VDSS and -2.5V VGS(TH) allow fast turn-on with standard 3.3V logic; body diode VSD = -0.7V minimizes forward drop during fault recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG4407LSS-13 | RDS(ON) = 15 mΩ @ -4.5V (vs. 19 mΩ), higher Qg = 130 nC, same SO-8 package | Better low-voltage drive but slower switching; less suitable for >300 kHz converters | Select when prioritizing gate-drive margin over switching efficiency in 3.3V-control systems |
| SI4435DY-T1-GE3 | RDS(ON) = 20 mΩ @ -4.5V, lower EAS = 180 mJ, no production UIS test data published | Lower avalanche ruggedness; not recommended for inductive loads without external clamping | Acceptable only in resistive or lightly inductive applications with strict cost constraints |
Compared with DMG4407LSS-13 and SI4435DY-T1-GE3, DMP4009SSS delivers superior avalanche robustness and lower conduction loss at -10V drive, making it the preferred choice for automotive and industrial power switches where reliability under transient stress is non-negotiable.

FAQ
Is DMP4009SSS qualified to AEC-Q101?
Yes, DMP4009SSS is AEC-Q101 qualified and manufactured in IATF 16949-certified facilities. It undergoes full stress testing including HTGB, HTRB, and UIS per AEC-Q101 Rev D, with PPAP documentation available upon request for automotive programs.
What is the maximum safe operating temperature for continuous use?
The junction temperature must not exceed +150°C. With RθJA = 58.5°C/W on a 1-inch² copper pad, the device supports continuous 2.1W dissipation at +70°C ambient - corresponding to ~9.2A at 11 mΩ RDS(ON) under steady-state conditions.
Can DMP4009SSS be used in synchronous rectification?
No - DMP4009SSS is a P-channel device intended for high-side switching. For synchronous rectification in buck converters, an N-channel MOSFET with appropriate gate drive (e.g., bootstrap or isolated supply) is required; this part's body diode is optimized for freewheeling, not active rectification.
Does the SO-8 package include an exposed drain pad?
Yes - the SO-8 package features an exposed drain paddle on the underside (pin 8), which must be soldered to a large PCB copper area to achieve the 58.5°C/W RθJA rating. Thermal vias beneath the pad are recommended for optimal heat transfer to internal layers.
