Product details
Overview
DMN2009UFDF from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type F) package, featuring 9 mΩ RDS(ON) at VGS = 4.5V, 12.8A continuous drain current at TA = +25°C, and low 0.6 mm profile. It serves as a high-efficiency power switch in compact DC-DC converters and load management circuits.
For engineers reviewing the DMN2009UFDF datasheet, DMN2009UFDF pinout, DMN2009UFDF application, or DMN2009UFDF equivalent, key selection criteria include its low gate threshold voltage (0.5–1.4 V), thermal resistance of 56 °C/W on FR-4 with thermal bias, and compatibility with 2.5V logic-level drive in space-constrained portable power systems.
Technical Context
This MOSFET employs a trench-gate process to achieve ultra-low RDS(ON) while maintaining fast switching performance: tD(ON) = 7 ns, tF = 14.6 ns, and Qg = 12.7 nC at VGS = 4.5V. Its body diode exhibits VSD = 0.7–1.2 V at IS = 8.5A, supporting synchronous rectification and reverse-current blocking.
The device operates across –55°C to +150°C junction temperature range, with RDS(ON) normalized to 1.0 at TJ = 25°C and rising to ~1.3× at 125°C under VGS = 4.5V. Its Ciss = 1083 pF and Crss = 110 pF enable stable operation in high-frequency buck regulators up to 2 MHz.
Key Specifications

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 |
|---|---|---|---|
| DMN2012LFG-7 | RDS(ON) = 12 mΩ @ VGS = 4.5V; higher 1.0 mm profile | Lower current rating (9.5 A) and reduced thermal performance (RθJA = 96.8 °C/W) | Preferred where cost sensitivity outweighs efficiency and size constraints |
| AO3414 | RDS(ON) = 7.5 mΩ @ VGS = 4.5V but larger SOT-23-3 package (2.9 × 1.3 × 1.0 mm) | Limited to ≤5 A continuous due to higher thermal resistance (RθJA = 150 °C/W) | Selected when legacy SOT-23 footprint compatibility is required over miniaturization |
Compared with DMN2009UFDF, DMN2012LFG-7 trades 33% higher RDS(ON) and double package height for lower unit cost, while AO3414 offers marginally lower on-resistance but sacrifices 3× PCB area and thermal capability-making DMN2009UFDF optimal for space- and efficiency-critical 2.5V-driven power switches.

FAQ
What is the maximum safe operating junction temperature for DMN2009UFDF?
The absolute maximum junction temperature is +150°C, verified per JEDEC JESD22-A104. Operation above this limit risks permanent parametric shift or bond-wire failure. Derating curves in Figure 13 confirm sustained 1.3 W dissipation only below +70°C ambient when using minimum pad layout; thermal-bias layout extends usable ambient range to +95°C.
Can DMN2009UFDF be used in a high-side configuration with 5V gate drive?
Yes-its ±12 V gate-source rating and 1.4 V maximum VGS(TH) ensure robust turn-on with 5V drive. However, high-side use requires a floating gate driver or charge pump, as the source potential rises with load. The device's low Qgd (1.4 nC) minimizes Miller plateau duration, reducing shoot-through risk during transition.
Is the thermal pad electrically isolated or connected to a specific terminal?
The exposed thermal pad is internally connected to the source (S) terminal, confirmed by the Equivalent Circuit diagram and mechanical drawings. It must be soldered to a PCB copper pour tied to the source net to achieve the specified RθJA = 56 °C/W; leaving it unconnected degrades thermal performance by >40%.
Does DMN2009UFDF meet automotive qualification standards out-of-the-box?
No-this part is not AEC-Q101 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; users must contact Diodes directly for qualified alternatives like the AEC-Q101-compliant DMN2009UFDQ-7 variant.
