Product details
Overview
DMP2075UVT from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for low-voltage, high-efficiency power switching in compact DC-DC converters and load switches. It delivers 75 mΩ RDS(ON) at VGS = −4.5 V, supports −3.8 A continuous drain current at +25°C, and features a low −1.0 V gate threshold voltage enabling direct interface with 3.3 V logic. Its TSOT26 package suits space-constrained portable power rails.
For engineers reviewing the DMP2075UVT datasheet, DMP2075UVT pinout, DMP2075UVT application, or DMP2075UVT equivalent, key selection criteria include verified RDS(ON) at −2.5 V gate drive, thermal resistance under PCB-defined layout (RθJA = 77 °C/W with 1-inch2 copper), and ESD-protected gate integrity per human-body model.
Technical Context
This MOSFET operates as a single-polarity high-side switch in buck converter synchronous rectification, USB port power control, and battery protection circuits. Its −20 V VDSS, ±8 V VGSS, and −1.2 V diode forward voltage (VSD) support robust reverse-biased body diode operation during discontinuous conduction mode.
The device uses planar trench-gate technology to balance low input capacitance (Ciss = 642 pF) and fast switching (tr = 22.6 ns, tf = 34.3 ns), while its 8.8 nC total gate charge enables efficient gate driver sizing for 1–2 MHz switching frequencies.
Key Specifications

|---|---|
| VDSS | −20 V: Maximum drain-source blocking voltage for 3.3 V/5 V system rail isolation |
| RDS(ON) | 75 mΩ @ VGS = −4.5 V: Enables <100 mW conduction loss at 3.8 A in compact layouts |
| ID (max) | −3.8 A @ TA = +25°C: Sustains full-load current in handheld device power paths |
| VGS(TH) | −0.3 to −1.0 V: Ensures reliable turn-on with standard 3.3 V GPIO without level-shifting |
| Ciss | 642 pF @ VDS = −10 V: Limits gate drive power and EMI in high-frequency SMPS designs |
| RθJA | 77 °C/W (with 1-inch² copper): Defines thermal derating for 1.6 W PD in industrial ambient |
| Qg | 8.8 nC @ VGS = −4.5 V: Determines minimum gate driver peak current for <100 ns switching transitions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UVT-7 | RDS(ON) = 48 mΩ @ −4.5 V; higher Qg = 12.5 nC; same TSOT26 package | Better conduction loss but slower switching; suited for <500 kHz applications prioritizing efficiency over speed | Select when thermal margin is constrained and gate drive strength exceeds 1 A peak |
| AO3401A | RDS(ON) = 85 mΩ @ −4.5 V; RθJA = 110 °C/W; SOT-23 package (larger footprint) | Lower cost but inferior thermal performance; requires larger PCB area for equivalent power dissipation | Choose for cost-sensitive consumer designs where board space allows SOT-23 and 1.2 W PD suffices |
Compared with DMG2305UVT-7 and AO3401A, DMP2075UVT offers optimal balance of low gate charge (8.8 nC), moderate RDS(ON) (75 mΩ), and superior thermal resistance (77 °C/W), making it preferred for space-limited, medium-frequency DC-DC and USB power switches.

FAQ
What is the maximum safe operating temperature for DMP2075UVT?
The junction temperature must not exceed +150°C under any condition. With RθJA = 77 °C/W and 1.6 W maximum power dissipation, ambient temperature must stay below +73°C for continuous operation at full rated current-verified using the 1-inch² copper thermal pad layout specified in DS40947.
Can DMP2075UVT be used in linear regulator applications?
No-it is optimized for switching operation only. Its RDS(ON) variation with temperature (±20% from −55°C to +150°C) and lack of SOA curves beyond pulsed operation make it unsuitable for linear pass element use; dedicated LDOs or bipolar pass transistors are recommended instead.
Is the body diode suitable for reverse polarity protection?
Yes-the integrated body diode has VSD = −1.2 V at −1.0 A and tRR = 13 ns, enabling effective reverse-current blocking in battery-input circuits. However, external Schottky diodes remain preferred where <0.4 V forward drop is mandatory for ultra-low-power standby modes.
Does DMP2075UVT require a gate resistor in typical switching applications?
Yes-a 10 Ω to 33 Ω series gate resistor is recommended to dampen ringing caused by trace inductance interacting with Ciss and Crss. This prevents false turn-on due to dv/dt coupling and ensures clean 22.6 ns rise time without overshoot, as validated in the datasheet's test circuit (RG = 3.0 Ω).
