Product details
Overview
DMP2040UVTQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -20V VDSS, 38 mΩ RDS(ON) at VGS = -4.5V, and -5.5A continuous drain current at TA = +25°C. It serves as a high-efficiency power switch in automotive DC-DC converters and motor control circuits requiring AEC-Q101 qualification and PPAP support.
For engineers reviewing the DMP2040UVTQ datasheet, DMP2040UVTQ pinout, DMP2040UVTQ application, or DMP2040UVTQ equivalent, key selection criteria include its TSOT26 package thermal performance (RθJA = 80 °C/W with thermal pad), low gate charge (Qg = 8.6 nC at VGS = -4.5V), and body diode reverse recovery characteristics (tRR = 9.8 ns, QRR = 2.7 nC).
Technical Context
This MOSFET employs a trench-gate structure optimized for low RDS(ON) and fast switching in high-frequency synchronous buck topologies. Its gate threshold voltage range (-0.6 V to -1.5 V) enables reliable turn-on with standard logic-level automotive controllers.
The device integrates an intrinsic body diode with VSD = -0.7 V at IS = -2.9 A and exhibits controlled reverse recovery behavior (QRR = 2.7 nC), supporting efficient freewheeling in half-bridge and H-bridge configurations without external Schottky supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V: Maximum drain-source blocking voltage for 12 V automotive rail protection and level-shifting applications. |
| RDS(ON) | 38 mΩ @ VGS = -4.5 V: Enables ≤150 mW conduction loss at 2 A load current in compact TSOT26 footprint. |
| ID (cont) | -5.5 A @ TA = +25°C: Supports sustained 5 A loads in thermally enhanced PCB layouts with 2 oz copper and thermal bias. |
| Qg | 8.6 nC @ VGS = -4.5 V: Reduces gate drive power and switching transition time in 500 kHz–1 MHz DC-DC controllers. |
| tRR | 9.8 ns: Limits voltage overshoot and EMI during body diode commutation in synchronous rectification. |
| RθJA | 80 °C/W (with thermal pad): Allows 1.5 W power dissipation at ≤70°C ambient in production-grade automotive PCBs. |
| VGS(TH) | -0.6 to -1.5 V: Ensures robust turn-on margin with ±0.5 V supply tolerance in 3.3 V/5 V gate driver systems. |

| 2 (S) | Source | Reference node for gate drive; tied to system ground or high-side return path in high-side switch configurations. |
| 3 (D) | Drain | Main current path output; electrically and thermally connected to exposed pad for low-inductance, high-current routing. |
| 4 (D) | Drain | Second drain connection reinforcing thermal and electrical path to PCB copper pour; not isolated from Pin 3. |
| 5 (D) | Drain | Third drain connection enhancing thermal conduction and current sharing across TSOT26's triple-drain layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UVTQ-7 | RDS(ON) = 42 mΩ @ -4.5 V; higher Qg = 10.5 nC; same TSOT26 package and AEC-Q101 rating. | Marginally lower efficiency in high-frequency DC-DC; suitable where gate drive strength exceeds requirement. | Select when cost sensitivity outweighs 10% conduction loss penalty and thermal margin is ample. |
| SI2301DDS-T1-GE3 | RDS(ON) = 115 mΩ @ -4.5 V; lower ID = -2.7 A; non-AEC-Q101; SOT-23 package. | Limited to non-safety-critical consumer or industrial loads; unsuitable for automotive PPAP programs. | Choose only for cost-driven non-automotive designs where 115 mΩ on-resistance and 2.7 A rating meet requirements. |
Compared with DMG2305UVTQ-7 and SI2301DDS-T1-GE3, DMP2040UVTQ delivers superior thermal performance (80 °C/W vs. ≥120 °C/W), tighter gate threshold control (-0.6 to -1.5 V), and verified PPAP readiness-making it the only option qualified for ASIL-B–related subsystems.

FAQ
What is the maximum safe operating junction temperature for DMP2040UVTQ?
The absolute maximum junction temperature is +150°C, validated per AEC-Q101 stress testing. Operation above +150°C risks permanent parametric shift and accelerated wear-out. Derating is required above +125°C ambient in high-power applications due to RDS(ON) increase and reduced SOA margins.
Can DMP2040UVTQ be used in high-side switch configurations with 12 V supply?
Yes-it supports high-side switching with gate drive referenced to source, provided VGS remains ≤ -4.5 V. Its -20 V VDSS rating accommodates 12 V nominal rails plus ISO 7637-2 load-dump transients up to 25 V, and its -1.5 V VGS(TH) ensures reliable turn-on with standard automotive gate drivers.
Does DMP2040UVTQ require external gate resistors for EMI control?
Not inherently-its 4.9 Ω gate resistance and 8.6 nC Qg yield moderate dV/dt (≈12 V/ns typical). However, a 5–10 Ω series gate resistor is recommended in high-noise environments (e.g., near ignition systems) to damp ringing and reduce radiated emissions without compromising switching speed.
How does the TSOT26 package's exposed drain pad affect PCB layout?
The exposed drain pad must be connected to a minimum 10 mm² copper pour with ≥4 thermal vias (0.3 mm diameter) to an internal ground plane. This achieves the specified RθJA = 80 °C/W; omitting vias or undersizing the pad increases junction temperature by ≥25°C at 1.2 W dissipation, risking thermal shutdown in automotive duty cycles.
