Product details
Overview
DMPH4009SSSQ-13 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 +25°C, with AEC-Q101 qualification and 175°C maximum junction temperature. It serves as a high-efficiency power switch in automotive and industrial DC-DC converters.
For engineers reviewing the DMPH4009SSSQ-13 datasheet, DMPH4009SSSQ-13 pinout, DMPH4009SSSQ-13 application, or DMPH4009SSSQ-13 equivalent, key selection criteria include its low RDS(ON) at -4.5V gate drive, robust UIS rating (-25.7A avalanche current), and SO-8 package thermal performance (RθJC = 5°C/W).
Technical Context
This MOSFET employs a trench-gate process optimized for low on-resistance while maintaining fast switching characteristics: Ciss = 5697 pF, Qg = 112 nC at VGS = -10V, and tF = 165 ns. Its body diode exhibits VSD = -0.7V at -1A, supporting synchronous rectification.
Rated for operation from -55°C to +175°C, it delivers stable RDS(ON) across temperature-normalized to 1.7× at 175°C vs. 25°C-and supports high-reliability automotive applications via IATF 16949 manufacturing and PPAP capability.

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 | RDS(ON) = 12.5 mΩ @ -10V; SO-8 but no exposed drain pad; RθJC = 10°C/W | Lacks thermal performance for sustained >7A operation without external heatsink | Select when cost sensitivity outweighs thermal margin; verify board copper area meets RθJA = 60°C/W requirement |
| IPD250N04LG | RDS(ON) = 2.5 mΩ @ -10V; TO-252 package; higher Qg = 22 nC; not AEC-Q101 qualified | Superior conduction loss but unsuitable for automotive due to qualification gap and larger footprint | Prefer for industrial 24V systems where space permits TO-252 and AEC-Q101 is not mandated |
Compared with DMTH4009LPS-13, DMPH4009SSSQ-13 delivers 5°C/W lower junction-to-case thermal resistance and AEC-Q101 validation; versus IPD250N04LG, it trades 2.5 mΩ ultra-low RDS(ON) for SO-8 manufacturability, automotive qualification, and proven UIS robustness.

FAQ
What is the maximum gate-source voltage rating for DMPH4009SSSQ-13?
The absolute maximum VGS rating is ±20 V, verified per DS45438 Rev. 3 Section "Maximum Ratings." Exceeding this risks permanent gate oxide damage. Recommended operating range is -10 V to 0 V for reliable enhancement-mode switching; gate drive circuits must include clamping or Zener protection if transient overshoot is possible.
Does DMPH4009SSSQ-13 require a gate resistor for safe operation?
A gate resistor is required to control dV/dt and prevent oscillation during switching. With Qg = 112 nC and typical driver output impedance, a 10 Ω resistor limits peak gate current to <1.5 A and ensures tR/tF remain within datasheet specs (41 ns/165 ns). Lower values risk ringing; higher values increase switching losses.
How is the exposed drain pad in the SO-8 package electrically connected?
The exposed drain pad is internally bonded to all four drain pins (Pins 3, 4, 5, 6) and forms the primary current and thermal path. It must be soldered to a dedicated PCB copper pour tied directly to the system ground or high-side rail-no thermal relief-to achieve RθJC = 5°C/W and sustain 11 A continuous current.
Is DMPH4009SSSQ-13 suitable for linear regulation applications?
No-it is optimized for switching operation only. Its Safe Operating Area (SOA) curve (Figure 12) shows limited DC capability: at VDS = -20 V, maximum linear current is ~1.5 A. For linear regulation, a MOSFET with wider SOA, lower thermal resistance, and specified linear-mode ratings (e.g., IXTP/NXP's linear FET series) is required.
