Product details
Overview
DMPH2040UVTQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -20V VDSS, 38 mΩ RDS(ON) at VGS = -4.5V, and -5.6A continuous drain current at TA = +25°C. It is AEC-Q101 qualified, operates up to +175°C, and targets automotive power management functions including DC-DC converters and motor control.
For engineers reviewing the DMPH2040UVTQ datasheet, DMPH2040UVTQ pinout, DMPH2040UVTQ application, or DMPH2040UVTQ equivalent, key selection criteria include its TSOT26 package thermal performance (RθJA = 83°C/W with enhanced layout), low gate charge (Qg = 8.6 nC at VGS = -4.5V), and body diode recovery characteristics (tRR = 9.8 ns).
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-temperature automotive environments. Its gate threshold voltage range of -0.6 V to -1.5 V ensures robust turn-on margin under supply variation, while the integrated body diode supports synchronous rectification and freewheeling in buck and H-bridge topologies.
The device's thermal design centers on the exposed drain pad in the TSOT26 package, enabling RθJC = 19°C/W to a PCB copper plane. Dynamic parameters-including Ciss = 834 pF, Coss = 133 pF, and Crss = 105 pF-are specified at VDS = -10 V and f = 1 MHz, supporting stable operation in 200–500 kHz DC-DC stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Maximum blocking voltage before avalanche conduction in high-side switch configurations |
| RDS(ON) | 38 mΩ @ VGS = -4.5 V - Enables <1.2 W conduction loss at 6 A in compact automotive modules |
| ID (continuous) | -5.6 A @ TA = +25°C - Supports mid-power load switching without forced airflow |
| Qg | 8.6 nC @ VGS = -4.5 V - Reduces gate drive power and enables efficient 3.3 V logic-level control |
| tRR | 9.8 ns - Minimizes reverse recovery losses during hard-switched transitions |
| TJ max | +175°C - Allows placement near heat sources (e.g., engine control units) without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH2004LPSQ-13 | RDS(ON) = 22 mΩ @ -4.5 V; higher ID = -12 A; PowerDI5060 package | Requires larger PCB area; better suited for >8 A continuous loads | Select when thermal budget allows larger footprint and higher current is needed |
| DMG2302UK-7 | RDS(ON) = 60 mΩ @ -4.5 V; lower ID = -3.2 A; SOT-23 package | Limited to <2.5 W dissipation; no AEC-Q101 qualification | Acceptable only for non-automotive, low-power analog switching |
Compared with DMTH2004LPSQ-13 and DMG2302UK-7, DMPH2040UVTQ uniquely balances AEC-Q101 compliance, TSOT26 space efficiency, and 38 mΩ RDS(ON)-making it optimal for space-constrained automotive modules where thermal resistance and gate drive simplicity are prioritized over peak current rating.

FAQ
What is the maximum safe operating temperature for DMPH2040UVTQ?
The DMPH2040UVTQ has a guaranteed operating junction temperature range of -55°C to +175°C. Its thermal design relies on proper PCB copper layout: with a 1-inch² 2 oz copper thermal pad, RθJA drops to 83°C/W, allowing 1.5 W continuous dissipation at +100°C ambient. Exceeding +175°C risks permanent parametric shift.
Does DMPH2040UVTQ support 3.3 V logic-level gate drive?
Yes-its gate threshold voltage (VGS(TH)) ranges from -0.6 V to -1.5 V, and RDS(ON) is specified down to VGS = -2.5 V (52 mΩ). At 3.3 V logic drive (i.e., VGS ≈ -3.3 V), typical RDS(ON) is ~42 mΩ, enabling functional operation in partial-drive fault modes without external level shifting.
How is the TSOT26 package thermally optimized for automotive use?
The TSOT26 package features an exposed drain pad that must be soldered to a dedicated PCB copper pour. With 2 oz copper and a 1-inch² thermal pad, RθJA improves from 125°C/W (standard FR-4) to 83°C/W. The RθJC of 19°C/W confirms direct thermal path from junction to solder joint-critical for sustained operation near engine compartments.
Is DMPH2040UVTQ suitable for synchronous rectification in buck converters?
Yes-the device's low Qg (8.6 nC), fast tRR (9.8 ns), and low RDS(ON) make it well-suited for low-side synchronous rectification in 12 V input buck converters. Its body diode forward voltage (VSD = -0.7 V typ.) ensures minimal conduction loss during dead-time, and the AEC-Q101 qualification guarantees reliability under automotive transient conditions.
