Product details
Overview
DMN2028UVT from Diodes Incorporated is an N-channel enhancement-mode MOSFET in 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 conduction loss and fast switching for compact DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMN2028UVT datasheet, DMN2028UVT pinout, DMN2028UVT application, or DMN2028UVT equivalent, key selection criteria include its 2.5V gate drive capability, 856 pF input capacitance, thermal resistance of 76°C/W (with thermal vias), and TSOT26 footprint compatibility with space-constrained portable power designs.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining controlled gate charge (Qg = 8.3 nC) and fast switching transitions (tr = 12.6 ns, tf = 22 ns). Its 0.4–1.5 V gate threshold enables reliable turn-on from 2.5V logic-level drivers.
The device integrates a body diode with 1.2 V forward voltage at 1.3 A and supports pulsed drain currents up to 40 A. Thermal design leverages a 15°C/W junction-to-case resistance and operates across –55°C to +150°C junction temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum safe operating temperature for DMN2028UVT-13?
The DMN2028UVT-13 has a maximum junction temperature of +150°C and operates safely from –55°C to +150°C. Its thermal resistance is 76°C/W with thermal vias on a 2 oz copper board. Derating is required above +85°C ambient; at +100°C ambient, maximum continuous drain current drops to ~4.1 A per Figure 4 in the datasheet.
Can DMN2028UVT-13 be used in a synchronous buck converter as the high-side switch?
Yes - DMN2028UVT-13 is qualified for high-side use in synchronous buck topologies. Its 20V VDS rating supports input rails up to 16V (with 20% margin), and its 8.3 nC total gate charge enables efficient drive with standard gate drivers like the ZXGD3003E6. Layout must minimize source inductance to prevent shoot-through during dead-time transitions.
Does DMN2028UVT-13 require a gate resistor, and if so, what value is recommended?
A gate resistor is required to dampen ringing and control dV/dt. For 1 MHz operation with a 1 Ω driver output impedance, a 5–10 Ω series resistor is recommended. Lower values (≤5 Ω) improve switching speed but increase EMI risk; higher values (>15 Ω) reduce EMI but raise switching losses. Layout-dependent parasitics necessitate empirical tuning on the target PCB.
Is the TSOT26 package of DMN2028UVT-13 compatible with standard reflow profiles?
Yes - the TSOT26 package is qualified for lead-free reflow per JEDEC J-STD-020, Level 1 moisture sensitivity. Peak temperature must not exceed 260°C, with ramp-up ≤3°C/s and time above 217°C limited to 60–150 seconds. The tin-finished leadframe ensures reliable solderability using standard SnAgCu paste and Type 3 or finer stencils.
