Product details
Overview
DMN2024UDH-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in a U-DFN3030-8 package, rated for 20V VDSS, 23mΩ RDS(ON) at VGS = 4.5V, and 5.2A continuous drain current at TA = +25°C. It delivers low conduction loss and fast switching for compact DC-DC converters and load-switching circuits in portable power management.
For engineers reviewing the DMN2024UDH-7 datasheet, DMN2024UDH-7 pinout, DMN2024UDH-7 application, or DMN2024UDH-7 equivalent, key selection criteria include its dual-channel layout, 1.8V gate-threshold capability, 6.5nC total gate charge, and thermal resistance of 71°C/W under enhanced PCB layout - all critical for high-density battery-powered designs.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single 3.0mm × 3.0mm U-DFN3030-8 package with exposed thermal pad. Its gate threshold voltage (0.35–1.0V) enables direct drive from 1.8V/2.5V logic, while low Ciss (647pF) and Crss (38pF) support MHz-range switching with minimal Miller effect.
The device features integrated body diodes with 0.65V typical forward voltage at 1A, and is characterized for avalanche energy (8mJ) and pulsed drain current (45A), supporting robust operation in transient-limited power rails and synchronous rectification topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - Maximum blocking voltage for 3.3V/5V input rail protection and buck converter high-side switching. |
| RDS(ON) | 23mΩ @ VGS = 4.5V - Enables ≤115mW conduction loss at 5.2A, critical for thermally constrained mobile PCBs. |
| ID (continuous) | 5.2A @ TA = +25°C - Sustains full-load current in dual-path load switches without forced airflow. |
| Qg | 6.5nC - Reduces gate drive power and allows use of low-current GPIOs or small drivers in space-constrained systems. |
| Ciss | 647pF - Limits capacitive loading on gate drivers and supports stable 1–2MHz PWM operation in point-of-load regulators. |
| TJ range | −55°C to +150°C - Qualified for extended industrial and automotive cabin ambient conditions without derating. |
Pinout & Package
Package: U-DFN3030-8, 3.0mm × 3.0mm × 0.6mm, thermally enhanced with exposed copper pad (Pin #1 ID marked).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | Source 1 | Low-side return path for Channel 1; tied to ground plane via thermal pad for optimal RθJC = 14°C/W. |
| 2 (G1) | Gate 1 | Control terminal for Channel 1; accepts 1.8V–10V logic; ESD-protected (HBM >2kV). |
| 3 (D1/D2) | Drain 1 / Drain 2 common | Shared drain node connecting both channels - enables parallel output or half-bridge configuration with external isolation. |
| 4 (G2) | Gate 2 | Independent control terminal for Channel 2; electrically isolated from G1 for differential or staggered timing. |
| 5 (S2) | Source 2 | Separate return path for Channel 2; allows independent current sensing or floating load driving. |
| 6–8 (Thermal Pad) | Exposed Copper Pad | Primary heat dissipation path; must be soldered to ≥1in² 2oz copper for 1.76W PD rating. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(ON) at 1.8V drive | 34mΩ @ VGS = 1.8V - Enables direct interface with ultra-low-voltage microcontrollers (e.g., ARM Cortex-M0+). |
| Matched dual-channel characteristics | ≤5% RDS(ON) mismatch between channels - ensures balanced current sharing in redundant or paralleled power paths. |
| Low Qgd/Qgs ratio | 1.7nC / 1.1nC = 1.55 - Minimizes Miller-induced shoot-through risk in synchronous buck high-side switching. |
| ESD-protected gate | HBM >2kV - Eliminates need for external gate protection in handheld and wearable assembly lines. |
| Green, halogen-free construction | <900ppm Br, <900ppm Cl, <1000ppm Sb - Meets IPC-1752A Tier 1 reporting and EU SCIP database requirements. |
Applications

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-7 | Same die, SO-8 package (larger footprint, higher RθJA = 62°C/W), no thermal pad. | Better suited for prototyping or legacy through-hole-compatible layouts; lower power density than U-DFN3030-8. | Select when board reworkability or hand-soldering is prioritized over size and thermal performance. |
| SI6926ADQ-T1-GE3 | 20V dual N-ch, but RDS(ON) = 30mΩ @ 4.5V, Qg = 8.5nC, and no avalanche rating. | Lacks specified EAS (8mJ) and 45A IDM; less robust in surge-prone industrial inputs. | Choose only if cost sensitivity outweighs need for transient ruggedness and sub-25mΩ conduction loss. |
Compared with DMN2024UDH-7, DMN2024LSD-7 trades miniaturization for assembly flexibility, while SI6926ADQ-T1-GE3 sacrifices avalanche capability and on-resistance for broader distributor availability - making DMN2024UDH-7 optimal for space- and reliability-critical battery-fed systems.

FAQ
What is the maximum safe operating temperature for DMN2024UDH-7?
The DMN2024UDH-7 has a junction temperature range of −55°C to +150°C. Under steady-state conditions with the recommended 1-inch square copper pad, it achieves 1.76W power dissipation at TA = +25°C. Derating begins at 71°C/W above ambient, requiring thermal simulation for enclosure-specific limits.
Can DMN2024UDH-7 be used in a synchronous buck converter high-side position?
No - DMN2024UDH-7 is a dual N-channel MOSFET with common-drain topology and no integrated bootstrap diode or level-shifting circuitry. It is designed for low-side switching, load switching, or half-bridge configurations where external gate drive and bootstrap management are provided.
Does DMN2024UDH-7 support 1.8V logic-level gate drive?
Yes - its gate threshold voltage ranges from 0.35V to 1.0V, and RDS(ON) is specified down to 34mΩ at VGS = 1.8V with ID = 3.5A. This enables direct drive from 1.8V I/O banks of modern microcontrollers without level shifters.
Is the thermal pad of DMN2024UDH-7 electrically connected to any internal node?
No - the exposed thermal pad (Pins 6–8) is electrically isolated and intended solely for thermal conduction. It must be soldered to a dedicated PCB copper pour connected to system ground or left floating per layout requirements; no internal silicon connection exists.
