Product details
Overview
DMN2040UVT-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in TSOT26 package, rated for 20V VDSS, 24 mΩ RDS(ON) at 4.5V VGS, and 6.7A continuous drain current at +25°C - optimized for high-efficiency DC-DC converters and power management in space-constrained portable electronics.
For engineers reviewing the DMN2040UVT-7 datasheet, DMN2040UVT-7 pinout, DMN2040UVT-7 application, or DMN2040UVT-7 equivalent, key selection criteria include low gate charge (7.5 nC), fast switching (tF = 9.4 ns), thermal resistance (RθJA = 77 °C/W with thermal vias), and RoHS-compliant "Green" construction.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining controlled gate charge and output capacitance (Coss = 91 pF). Its 0.4–1.5 V gate threshold enables reliable turn-on from 2.5 V logic-level drivers.
The device integrates a body diode with VSD = 0.7–1.2 V at 1.3 A and tRR = 12 ns, supporting synchronous rectification and flyback recovery in compact buck and boost topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - supports input rails up to 16 V with margin for transient spikes in USB-powered and Li-ion battery systems. |
| RDS(ON) | 24 mΩ @ 4.5 V VGS - limits conduction loss to ≤0.7 W at 6 A, enabling >92% efficiency in 3.3 V/5 V point-of-load converters. |
| Qg | 7.5 nC - reduces gate drive power and enables operation with low-current microcontroller GPIOs or integrated PWM controllers. |
| Ciss | 667 pF - balances switching speed and EMI control; compatible with 1–5 MHz switching frequencies without excessive ringing. |
| RθJA | 77 °C/W (with thermal vias) - allows 1.6 W dissipation at ≤100°C junction rise above ambient on standard 2 oz copper PCBs. |
| ID (max) | 6.7 A @ +25°C - sustains peak load currents in single-phase buck stages powering FPGAs, PMICs, or display drivers. |
Pinout & Package
Package: TSOT26 - ultra-thin surface-mount package (2.9 × 2.8 × 0.8 mm), lead-free, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Power return path for channel current | Internally connected to exposed pad; must be soldered to large copper pour for thermal and electrical performance. |
| 2 (Gate) | Control terminal for channel conduction | Low-input-capacitance node (Ciss = 667 pF); requires <1.2 Ω series gate resistor to damp oscillation during fast switching. |
| 3 (Drain) | High-side power input node | Connected to switched rail; layout must minimize loop inductance to reduce voltage overshoot during turn-off. |
| 4 (Source) | Redundant source connection | Electrically tied to Pin 1; improves current sharing and thermal conduction when both pins are routed to ground plane. |
| 5 (Drain) | Redundant drain connection | Electrically tied to Pin 3; enhances current handling and reduces package resistance in high-pulsed-current paths. |
| 6 (Gate) | Redundant gate connection | Electrically tied to Pin 2; lowers gate loop inductance and improves noise immunity in high-dv/dt environments. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 2.5 V VGS | 32 mΩ - enables direct drive from 2.5 V I/O domains (e.g., FPGA banks, low-voltage MCUs) without level-shifting. |
| Fast switching with low Qgd/Qgs | Qgd = 2.5 nC, Qgs = 0.8 nC - yields low Miller plateau time, reducing overlap loss in hard-switched topologies. |
| Thermally enhanced TSOT26 | RθJA = 77 °C/W with thermal vias - achieves 150°C max junction temperature at 1.6 W dissipation on production-grade PCBs. |
| Body diode with low QRR | QRR = 3.4 nC - minimizes reverse-recovery losses in asynchronous buck and flyback converters operating above 500 kHz. |
| Halogen- and antimony-free "Green" construction | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - meets IPC-1752A Class 3 reporting requirements for automotive and industrial OEMs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2041UVT-7 | RDS(ON) = 28 mΩ @ 4.5 V, Qg = 6.2 nC, same TSOT26 package | Slightly higher conduction loss but lower gate drive demand; better for 1–3 MHz ultra-high-frequency designs | Select when prioritizing gate drive simplicity over minimal conduction loss at <5 A loads. |
| AO3400A | RDS(ON) = 28 mΩ @ 4.5 V, Ciss = 830 pF, SO-23 package (larger footprint) | Higher input capacitance increases gate drive loss; SO-23 requires more PCB area and has higher RθJA (120 °C/W) | Choose only if legacy SO-23 footprint compatibility is mandatory and thermal headroom exceeds 25°C/W. |
Compared with DMN2040UVT-7, DMN2041UVT-7 trades 4 mΩ higher RDS(ON) for 1.3 nC lower Qg, improving high-frequency efficiency; AO3400A offers identical voltage rating but inferior thermal performance and larger footprint, limiting use in ultra-dense layouts.

FAQ
What is the maximum continuous drain current for DMN2040UVT-7 at +75°C ambient?
The DMN2040UVT-7 supports 5.3 A continuous drain current at +75°C ambient temperature under standard FR-4 PCB conditions with 2 oz copper and thermal vias. This derating reflects junction-to-ambient thermal resistance of 77 °C/W and a maximum junction temperature of 150°C. Layout improvements can extend usable current at elevated temperatures.
Can DMN2040UVT-7 be used in a synchronous rectifier configuration?
Yes - its body diode exhibits tRR = 12 ns and QRR = 3.4 nC, enabling efficient synchronous rectification in buck and flyback converters up to 1 MHz. Gate drive timing must ensure the MOSFET turns on before the body diode conducts significantly, typically requiring precise dead-time control.
Is the TSOT26 package of DMN2040UVT-7 compatible with standard reflow profiles?
Yes - the TSOT26 package is qualified for JEDEC J-STD-020 Level 1 moisture sensitivity and withstands standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C). The tin-finished copper leadframe ensures robust solderability per MIL-STD-202, Method 208.
Does DMN2040UVT-7 require external gate resistors in typical 2 MHz switching applications?
Yes - a 1–5 Ω series gate resistor is recommended to damp high-frequency ringing caused by gate-drain capacitance (Crss = 83 pF) and PCB trace inductance. Omitting it risks shoot-through in half-bridge configurations and EMI compliance failure above 500 kHz.
