Product details
Overview
DMP2040UVT-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TSOT26 package, rated for -20V VDSS, 38mΩ RDS(ON) @ VGS = -4.5V, and -5.5A continuous drain current at TA = +25°C. It serves as a high-efficiency synchronous rectifier or load switch in compact DC-DC converters and motor control stages.
For engineers reviewing the DMP2040UVT-7 datasheet, DMP2040UVT-7 pinout, DMP2040UVT-7 application, or DMP2040UVT-7 equivalent, key selection criteria include verified low RDS(ON) at -4.5V gate drive, thermal resistance of 80°C/W under enhanced PCB layout, and TSOT26 footprint compatibility with space-constrained power rails.
Technical Context
This MOSFET operates in enhancement mode with a gate threshold voltage (VGS(TH)) ranging from -0.6V to -1.5V, enabling reliable turn-on with standard logic-level negative gate drive. Its body diode exhibits 9.8ns reverse recovery time and 2.7nC QRR, supporting high-frequency switching in buck converters.
The device features 834pF input capacitance (Ciss) and 105pF reverse transfer capacitance (Crss) at VDS = -10V, contributing to fast 5.8ns turn-on delay and 14.6ns turn-off fall time under 6Ω gate resistance test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum blocking voltage for low-voltage P-channel switching in 3.3V/5V rail systems |
| RDS(ON) | 38mΩ @ VGS = -4.5V - Confirmed on-resistance enabling ≤200mW conduction loss at 5A load |
| ID (continuous) | -5.5A @ TA = +25°C - Sustained current capability with 1.5W power dissipation on 2oz copper FR-4 |
| Ciss | 834pF - Input capacitance defining gate drive energy requirement and switching speed limit |
| tRR | 9.8ns - Body diode reverse recovery time critical for minimizing shoot-through loss in synchronous rectification |

| 2 (S) | Source | Reference node for gate drive; tied to system ground or positive rail depending on high-side switch topology |
| 3 (D) | Drain | Main current path output; connected to exposed pad for thermal conduction to PCB copper |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2040LFG-7 | N-channel counterpart with 20V rating and 28mΩ RDS(ON) @ VGS = +4.5V; requires high-side gate driver | Suitable only where N-channel topology is feasible (e.g., low-side switching or driven half-bridge) | Select when board layout allows gate driver integration and lower RDS(ON) outweighs added complexity |
| SI2301DDS-T1-GE3 | P-channel, -20V, 115mΩ RDS(ON) @ VGS = -4.5V; higher on-resistance but identical TSOT26 footprint | Acceptable for <1A loads where thermal margin permits higher conduction loss | Choose for cost-sensitive designs with relaxed efficiency targets and legacy footprint compatibility |
Compared with DMN2040LFG-7 and SI2301DDS-T1-GE3, DMP2040UVT-7 delivers optimal balance of low RDS(ON), logic-level P-channel operation, and thermal performance-making it preferred for space-constrained, high-efficiency 3.3V–12V power rails without gate driver overhead.

FAQ
What is the maximum safe operating temperature for DMP2040UVT-7?
The device supports junction temperatures from -55°C to +150°C. Under continuous 1.5W power dissipation with 2oz copper thermal pad, junction temperature remains below 125°C at ambient 70°C-verified via RθJA = 80°C/W and SOA curve validation in Figure 12.
Can DMP2040UVT-7 be used in high-side switch configurations without a gate driver?
Yes. With VGS(TH) down to -0.6V and guaranteed enhancement at -4.5V, it fully turns on when gate is pulled to ground while source connects to positive rail-enabling self-contained high-side switching in 5V systems without external level-shifting circuitry.
How does the TSOT26 package affect thermal performance compared to SO-8?
TSOT26's exposed drain pad provides 16°C/W RθJC, outperforming SO-8's typical 40–50°C/W. However, its smaller copper area yields higher RθJA (80°C/W) unless augmented with ≥1-inch² 2oz copper-making PCB layout more critical than in larger packages.
Is DMP2040UVT-7 suitable for automotive applications?
No. It is not AEC-Q101 qualified, lacks automotive-grade screening, and has no specified operation above +125°C junction temperature. For automotive use, Diodes' AP2310GH and similar AEC-Q101 P-channel MOSFETs are recommended alternatives.
