Product details
Overview
DMN2024UFX from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in a V-DFN2050-4 package, rated for 20V VDSS, 22 mΩ RDS(ON) @ 4.5V VGS, 8A ID at TC = +25°C, and featuring ESD protection. It serves as a compact, low-loss power switch in space-constrained DC-DC converter output stages and load-switching circuits.
For engineers reviewing the DMN2024UFX datasheet, DMN2024UFX pinout, DMN2024UFX application, or DMN2024UFX equivalent, key selection criteria include its dual-channel layout, 2.0 mm × 5.0 mm footprint, low gate charge (6.5 nC @ 4.5V), fast switching (tR = 140 ns), and thermal resistance of 7.4 °C/W (junction-to-case).
Technical Context
This dual MOSFET integrates two independent N-channel devices sharing a common source terminal configuration per channel (S1/G1/D1 and S2/G2/D2), enabling synchronous rectification or complementary half-bridge operation without external isolation. Its low RDS(ON) at 2.5V gate drive supports direct interfacing with 3.3V logic controllers.
The device uses trench-gate process technology to achieve high cell density and low input capacitance (Ciss = 647 pF), while maintaining robust avalanche capability (EAS = 8 mJ) and body diode recovery performance (tRR = 245 ns, QRR = 149 nC) suitable for hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum drain-source blocking voltage for 3.3V/5V rail applications |
| RDS(ON) | 22 mΩ @ 4.5V VGS - Enables <170 mW conduction loss at 4A continuous current |
| ID (max) | 8 A @ TC = +25°C - Supports high-current load switching on thermally enhanced PCBs |
| Qg | 6.5 nC @ VGS = 4.5V - Reduces gate driver power demand and switching transition time |
| RθJC | 7.4 °C/W - Allows direct thermal coupling to copper pour for efficient heat extraction |
| Ciss | 647 pF - Limits Miller-induced turn-on risk in high-dV/dt environments |
| tRR | 245 ns - Minimizes reverse recovery losses during freewheeling in buck converters |

Applications
| USB Power Delivery Switch | DC-DC Synchronous Rectifier |
|---|---|
Use Scenario: Bidirectional 5–20V USB PD port with overcurrent and short-circuit protection. IC Role / Device Role / Timing Role: Dual-channel load switch controlling VBUS path and CC line power routing. Use Value: 22 mΩ RDS(ON) limits voltage drop to <110 mV at 5A, preserving PD negotiation margins. |
Use Scenario: Secondary-side rectification in 12V→3.3V buck converter for FPGA core supply. IC Role / Device Role / Timing Role: Low-side synchronous rectifier replacing Schottky diode in continuous conduction mode. Use Value: 6.5 nC Qg allows clean 1 MHz switching with minimal gate drive loss and reduced EMI. |
| Hot-Swap Controller Interface | Industrial Sensor Node Power Gate |
Use Scenario: Inrush-limited 12V backplane insertion for modular PLC I/O cards. IC Role / Device Role / Timing Role: High-side power switch controlled by hot-swap controller's gate driver output. Use Value: 400 Ω Rg enables precise slew-rate control of VDS during soft-start, limiting dI/dt to <10 A/ms. |
Use Scenario: Battery-powered environmental sensor node requiring ultra-low standby leakage. IC Role / Device Role / Timing Role: Main power gate isolating MCU, radio, and analog front-end during sleep mode. Use Value: 1 µA IDSS at 20V ensures <1 µW quiescent loss, extending 10-year battery life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2024LSD-13 | Same die in SO-8 package; RDS(ON) = 24 mΩ @ 4.5V; higher RθJA (60 °C/W vs. 136 °C/W) | Preferred where board-level reworkability and manual assembly are required | Select when thermal pad soldering is impractical but higher junction temperature rise is acceptable |
| AOB2022L | Single-channel 20V MOSFET (20 mΩ @ 4.5V); no shared drain; Qg = 5.8 nC; TO-252 package | Suitable for discrete half-bridge layouts where channel independence is critical | Choose when separate drain routing is needed to avoid shoot-through in bridge configurations |
Compared with DMN2024UFX, DMN2024LSD-13 trades compactness and thermal performance for ease of handling and visual inspection, while AOB2022L offers lower gate charge and true channel isolation at the cost of doubled footprint and component count for dual-switch functions.

FAQ
What is the maximum safe operating temperature for DMN2024UFX?
The DMN2024UFX has an absolute maximum junction temperature of +150°C and a storage temperature range of –55°C to +150°C. Under continuous 8A operation with 2.1W power dissipation on a 1-inch² copper pad, junction temperature rise is ~15.5°C above ambient, allowing reliable operation up to +134°C ambient if heatsinking is adequate.
Can DMN2024UFX be used in linear regulator applications?
No - DMN2024UFX is not characterized or guaranteed for linear-mode operation. Its Safe Operating Area (SOA) curve shows only single-pulse capability down to DC at low VDS; sustained linear operation risks thermal runaway due to positive temperature coefficient of RDS(ON) and lack of SOA derating data beyond 10 ms pulses.
Is the exposed thermal pad electrically connected to any internal node?
Yes - the exposed pad is internally connected to the source terminals (S1 and S2) and must be soldered to a PCB copper pour tied to system ground. This connection provides both thermal conduction and low-inductance grounding for high-frequency switching noise suppression.
Does DMN2024UFX meet automotive qualification standards?
DMN2024UFX is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade variants (e.g., DMN2024UFXQ-7) with PPAP documentation, IATF 16949 manufacturing, and extended temperature testing; standard DMN2024UFX-7 is intended for commercial and industrial applications only.
