Product details
Overview
DMN2024UFDF from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in a U-DFN2020-6 package, optimized for low RDS(ON) and fast switching in compact power stages. It delivers 7.1A continuous drain current at VGS = 4.5V with 22mΩ on-resistance, features ESD-protected gate, and supports battery management and DC-DC converter applications.
For engineers reviewing the DMN2024UFDF datasheet, DMN2024UFDF pinout, DMN2024UFDF application, or DMN2024UFDF equivalent, key selection criteria include its 1.5V–4.5V gate threshold range, 0.6mm profile, 4mm² footprint, thermal resistance of 75°C/W (with copper pad), and compatibility with low-voltage logic-level drive in space-constrained portable and automotive subsystems.
Technical Context
This MOSFET employs a trench-gate silicon process to achieve low gate charge (6.5nC at VGS = 4.5V) and fast switching (tD(ON) = 98ns, tF = 434ns), enabling high-frequency operation in synchronous buck converters. Its RDS(ON) remains stable across −55°C to +150°C junction temperature, with normalized variation ≤1.6× at 150°C.
The device integrates an intrinsic body diode with VSD = 0.7V at IS = 5A and QRR = 149nC, supporting efficient reverse recovery in flyback and OR-ing configurations. Gate protection includes ±10V VGSS rating and NiPdAu-plated terminals for robust solderability and reliability.

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 |
|---|---|---|---|
| DMN2026UFDF-7 | RDS(ON) = 26mΩ @ 4.5V; 6.5A ID; same U-DFN2020-6 package | Higher on-resistance increases conduction loss by ~18% at 7A; suitable where cost sensitivity outweighs efficiency | Select when BOM cost reduction is prioritized over thermal margin in low-duty-cycle loads |
| AO3414 | RDS(ON) = 28mΩ @ 4.5V; SO-23 package; no exposed thermal pad; RθJA = 150°C/W | Larger footprint (2.9mm × 1.6mm) and inferior thermal performance limit use to <3A continuous loads | Choose only for legacy SO-23 layouts where re-spinning PCB is prohibitive |
Compared with DMN2024UFDF, DMN2026UFDF trades 4mΩ higher RDS(ON) for lower unit cost in identical packaging, while AO3414 sacrifices thermal capability and size for SO-23 compatibility-neither matches the 22mΩ/7.1A/0.6mm combination in U-DFN2020-6.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The DMN2024UFDF supports 5.6A continuous drain current at TA = +70°C with a 1-inch² 2oz copper pad per datasheet Note 6. This derating reflects thermal limits under real-world PCB conditions-not just junction temperature-but assumes proper layout with the exposed pad fully soldered to ground plane.
Is this MOSFET qualified for automotive applications?
The DMN2024UFDF itself is not AEC-Q101 qualified; however, Diodes offers automotive-grade variants (e.g., DMN2024UFDFQ-7) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. Standard versions are intended for industrial and consumer applications unless explicitly marked with 'Q' suffix.
Can it be used in a high-side configuration with 3.3V gate drive?
Yes-its VGS(TH) max of 1.0V and RDS(ON) = 26mΩ at VGS = 2.5V ensure reliable enhancement with 3.3V logic. For high-side use, a gate driver with bootstrap or charge-pump capability is required to maintain VGS > 2.5V during 100% duty cycle, as the device lacks integrated level-shifting.
What is the recommended PCB pad layout for thermal performance?
Per Diodes' package outline DS40595 Rev. 8-2, the exposed pad must be connected to a minimum 1-inch² 2oz copper area using ≥4 thermal vias (0.3mm diameter, spaced ≤1mm apart). The suggested pad dimensions are X = 0.400mm, Y = 0.425mm, D2a = 0.38mm, and E2a = 0.70mm-deviations reduce RθJA from 75°C/W to >100°C/W.
