Product details
Overview
DMN2026UVT-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in a TSOT26 package, rated for 20V VDS, 24 mΩ RDS(ON) at 4.5V VGS, and 6.2A continuous drain current at +25°C. It delivers low gate charge (10 nC at VGS = 4.5V), fast switching (tr = 66 ns), and ESD-protected gate - optimized for high-efficiency DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMN2026UVT-7 datasheet, DMN2026UVT-7 pinout, DMN2026UVT-7 application, or DMN2026UVT-7 equivalent, key selection criteria include its 2.5V logic-level gate drive capability, 1.15W power dissipation on FR-4, 887 pF input capacitance, and thermal resistance of 107°C/W (junction-to-ambient, steady-state).
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(ON) while maintaining robust body diode performance (VSD = 0.7–1.2 V at 1.3 A) and low reverse recovery charge (QRR = 96 nC). Its gate threshold voltage (0.4–1.5 V) enables reliable turn-on with 2.5V microcontroller outputs.
The device features integrated gate protection diodes and is characterized for operation across –55°C to +150°C junction temperature. Thermal design is supported by validated RθJC = 16°C/W and transient thermal impedance curves for pulsed-load analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 20 V - supports 12V rail switching and USB-powered systems without derating |
| RDS(ON) @ 4.5V | 24 mΩ max - enables <150 mW conduction loss at 6.2A, critical for thermally constrained PCBs |
| Qg @ 4.5V | 10 nC - reduces gate driver power demand and switching transition time in high-frequency converters |
| Ciss | 887 pF - determines Miller effect and required gate drive strength for stable 1–2 MHz operation |
| tr/tf | 66 ns / 197 ns - enables efficient hard-switched topologies up to ~1.5 MHz with minimal overlap loss |
| PD (FR-4) | 1.15 W - defines maximum continuous power handling on standard 1-oz copper board without thermal vias |
| VGS(TH) | 0.4–1.5 V - ensures full enhancement with 1.8V/2.5V/3.3V logic families, including low-voltage MCUs |
Pinout & Package
Package: TSOT26 - ultra-thin surface-mount package (1.0 mm height, 2.9 × 2.8 mm footprint), RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Source | Common return path for load current; tied to ground or low-side reference in buck/boost configurations |
| 2 (G) | Gate | Control terminal requiring ≤±10 V drive; ESD-protected with internal diode clamp |
| 3 (D) | Drain | High-side connection point for load; carries full switched current and withstands 20 V transients |
| 4 (S) | Source (redundant) | Second source bond for lower parasitic inductance and improved thermal spreading in high-current paths |
| 5 (D) | Drain (redundant) | Second drain bond to reduce channel resistance and improve current sharing under pulse loads |
| 6 (G) | Gate (redundant) | Secondary gate bond minimizes gate loop inductance, critical for noise immunity in high-dV/dt environments |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS ≥ 2.5 V - eliminates need for gate boosters in portable 3.3V/2.5V systems |
| Low Qgd/Qgs ratio | Qgd = 1.8 nC, Qgs = 1.3 nC - improves hard-switching efficiency and reduces Miller-induced shoot-through risk |
| Body diode softness | tRR = 119 ns, QRR = 96 nC - minimizes voltage overshoot and EMI during synchronous rectifier commutation |
| Thermal vias compatible layout | Validated PD = 1.75 W with 2-oz copper + thermal vias - enables >2× power handling vs. standard FR-4 |
| ESD-protected gate | HBM rating ≥ 2 kV - prevents field failure during assembly and handling without external Zener clamps |

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 |
|---|---|---|---|
| DMN2026LVT-7 | RDS(ON) = 28 mΩ @ 4.5V; same TSOT26 package and pinout | Slightly higher conduction loss; identical thermal and switching specs | Select when marginally higher RDS(ON) is acceptable for cost-sensitive volume production |
| AO3400A | RDS(ON) = 28 mΩ @ 4.5V; SO-23 package (larger footprint, higher RθJA) | Higher thermal resistance (150°C/W) limits power density; slower tr (10 ns longer) | Choose only if legacy SO-23 board space is fixed and thermal headroom exceeds 25°C |
Compared with DMN2026LVT-7 and AO3400A, the DMN2026UVT-7 offers the lowest RDS(ON) in TSOT26, enabling highest power density in space-constrained DC-DC modules and fastest switching among logic-level 20V MOSFETs with matched package size.

FAQ
What is the maximum continuous drain current at +85°C ambient?
At TA = +85°C with standard FR-4 mounting (no thermal vias), the maximum continuous drain current is derated to 4.3 A based on RθJA = 107°C/W and TJ(max) = +150°C. With 2-oz copper and thermal vias, it supports 5.8 A at +85°C per the 1.75 W PD rating.
Is the DMN2026UVT-7 suitable for synchronous rectification in a 1 MHz buck converter?
Yes - its 10 nC total gate charge, 66 ns rise time, and 887 pF Ciss enable efficient synchronous operation at 1 MHz. The low Qgd/Qgs ratio further suppresses Miller-induced false turn-on, critical for stability in high-frequency topologies.
Does the TSOT26 package support reflow soldering per JEDEC J-STD-020?
Yes - the DMN2026UVT-7 is qualified for moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/60% RH and subjected to standard lead-free reflow profiles (peak 260°C) without baking or special handling.
How does the body diode performance compare to Schottky alternatives?
The integrated body diode has VSD = 0.7–1.2 V at 1.3 A and tRR = 119 ns. While forward voltage is higher than Schottky diodes, its soft recovery and co-packaged integration eliminate layout parasitics and reduce EMI - making it preferable to discrete Schottky + MOSFET solutions in compact, high-reliability designs.
