Product details
Overview
DMN2024UQ from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in SOT23 package, featuring 20V VDSS, 25 mΩ RDS(ON) @ 4.5V VGS, and 6.8A continuous drain current at TA = +25°C. It delivers low-input capacitance (647 pF Ciss) and fast switching (98 ns tD(ON)), enabling high-efficiency DC-DC converters and automotive power management.
For engineers reviewing the DMN2024UQ datasheet, DMN2024UQ pinout, DMN2024UQ application, or DMN2024UQ equivalent, key selection criteria include gate threshold voltage (0.5–0.9 V), thermal resistance (92 °C/W on 1"×1" FR-4), body diode forward voltage (0.8–1.2 V), and ESD-protected gate architecture for robust system-level reliability.
Technical Context
This MOSFET employs a planar trench-gate structure optimized for low RDS(ON) while maintaining controlled gate charge (6.5 nC Qg) and minimized Crss (38 pF) to reduce Miller-induced turn-off delay. Its 1.8V–4.5V logic-level gate drive supports direct interfacing with 3.3V/5V microcontrollers.
The device integrates a monolithic body diode with 245 ns reverse recovery time and 149 nC QRR, enabling synchronous rectification in buck topologies. Thermal design is constrained by RθJA = 92 °C/W under high-copper PCB conditions and 159 °C/W on standard FR-4 - critical for sustained 5.5A operation at TA = +70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum blocking voltage in off-state; defines use in ≤12V nominal systems with transient margin. |
| RDS(ON) | 25 mΩ @ 4.5V VGS - Enables <170 mW conduction loss at 6.5A, critical for thermally constrained SOT23 layouts. |
| ID (max) | 6.8 A @ TA = +25°C - Continuous current rating limited by package thermal resistance and copper area. |
| Ciss | 647 pF - Low input capacitance reduces gate drive power and speeds up turn-on with minimal overshoot. |
| tD(ON) | 98 ns - Short turn-on delay supports >1 MHz switching in compact DC-DC regulators. |
| VGS(TH) | 0.5–0.9 V - Ultra-low threshold enables reliable turn-on with weak drivers or battery-voltage-limited supplies. |
| Qg | 6.5 nC - Total gate charge determines required driver peak current and switching energy loss. |
Pinout & Package
SOT23-3 package: surface-mount, 3-terminal plastic case with matte tin-plated copper leadframe; UL 94V-0 rated molding compound; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main current path output terminal | Connected to load or switching node; carries full ID and must be routed with low-inductance layout for EMI control. |
| Gate (G) | Control electrode | ESD-protected input requiring <10 µA leakage; driven by logic-level signal; sensitive to ringing due to 400 Ω Rg. |
| Source (S) | Reference node and current return path | Common connection point for gate drive reference and body diode cathode; must be low-impedance to minimize VGS error. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 2.5V VGS | 29 mΩ - Ensures usable conduction even under brown-out or low-VCC conditions in automotive modules. |
| ESD-protected gate | HBM ±2 kV - Eliminates need for external gate protection in assembly and field environments. |
| Fast body diode recovery | tRR = 245 ns - Reduces cross-conduction losses in synchronous buck converters operating above 500 kHz. |
| AEC-Q101 qualification | PPAP-capable, IATF 16949 manufacturing - Validated for automotive powertrain and body electronics applications. |
| Green compound | Br+Cl <1500 ppm, Sb <1000 ppm - Meets global halogen-free requirements without compromising moldability or thermal performance. |

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 |
|---|---|---|---|
| DMN2024LQ-7 | Same die, SOT23-3, but rated for 20V VDSS and 22 mΩ RDS(ON) @ 4.5V - tighter RDS(ON) binning. | Higher yield in high-current 5V logic-driven loads where <22 mΩ is required for thermal margin. | Select when production BOM requires guaranteed max RDS(ON) ≤22 mΩ at 4.5V. |
| AO3400 | 20V VDSS, 28 mΩ RDS(ON) @ 4.5V, 5.7A ID, no AEC-Q101 qualification or ESD protection. | Cost-sensitive consumer-grade DC-DC converters where automotive qualification is not required. | Choose only for non-automotive applications lacking PPAP or ESD robustness requirements. |
Compared with DMN2024LQ-7, the DMN2024UQ offers broader RDS(ON) tolerance (25 mΩ vs. 22 mΩ) but identical AEC-Q101 compliance and ESD rating; versus AO3400, it adds automotive qualification and gate ESD protection at slightly higher RDS(ON), making it suitable for safety-critical 12V systems.

FAQ
Is DMN2024UQ suitable for high-frequency switching above 1 MHz?
Yes - its 98 ns turn-on delay, 140 ns rise time, and 6.5 nC total gate charge enable efficient operation up to 1.2 MHz in buck converters. However, layout parasitics must be minimized, and gate drive strength ≥1 A peak is recommended to fully exploit its speed capability.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C, but continuous operation should be limited to ≤125°C to ensure long-term reliability. At 6.8A and 25 mΩ, power dissipation reaches 1.16W - exceeding the 1.4W rating only under worst-case thermal conditions (e.g., no copper pour), so derating is essential.
Does DMN2024UQ require external gate resistors for stability?
A series gate resistor of 5–10 Ω is recommended to dampen ringing caused by the 400 Ω intrinsic gate resistance interacting with PCB trace inductance. This prevents false turn-on during fast dv/dt events and improves EMI performance without significantly impacting switching speed.
Can DMN2024UQ be used in high-side configuration with 12V supply?
Yes - its ±10V VGSS rating and 20V VDSS allow use in high-side configurations with bootstrap gate drive. However, the 0.5–0.9V VGS(TH) requires careful bootstrap capacitor sizing to maintain >4.5V gate voltage across duty cycles and temperature extremes.
