Product details
Overview
DMN2022UFDF-13 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in U-DFN2020-6 package, optimized for high-efficiency power management with RDS(ON) = 22 mΩ @ VGS = 4.5V, 7.9 A continuous drain current at +25°C, and ESD-protected gate. It serves as a low-side switch in compact DC-DC converters and battery protection circuits.
For engineers reviewing the DMN2022UFDF-13 datasheet, DMN2022UFDF-13 pinout, DMN2022UFDF-13 application, or DMN2022UFDF-13 equivalent, key selection criteria include low gate threshold (0.5–1.0 V), fast switching (tD(ON) = 56 ns), thermal resistance (RθJA = 60 °C/W with copper pad), and 0.6 mm profile for space-constrained PCB layouts.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining robust switching performance. Its gate threshold voltage range (0.5–1.0 V) enables direct drive from 1.8 V and 2.5 V logic, and its integrated ESD protection (HBM > 2 kV) eliminates need for external gate clamping in portable systems.
The device features a source-drain diode with VSD = 0.7–1.0 V at IS = 5 A and exhibits avalanche capability (IAS = 12 A, EAS = 8 mJ), supporting reliable operation under inductive load transients in synchronous buck stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - supports input rails up to 18 V with 10% margin for transient spikes |
| RDS(ON) | 22 mΩ @ VGS = 4.5V - delivers ≤1.4 W conduction loss at 7.9 A, critical for thermally constrained designs |
| ID (continuous) | 7.9 A @ TA = +25°C - sufficient for 5–6 A load currents in 12 V input DC-DC converters |
| Qg | 9.8 nC @ VGS = 4.5V - enables efficient gate driving with low-power controllers and reduces switching loss |
| RθJA | 60 °C/W (with 1-inch² copper pad) - allows 2.03 W power dissipation before junction exceeds 150°C |
| VGS(TH) | 0.5–1.0 V - ensures full enhancement at 1.8 V logic, eliminating level-shifter requirement |
| Ciss | 907 pF - balances switching speed and EMI control in MHz-range synchronous regulators |
Pinout & Package
U-DFN2020-6 (Type F) package: 2.0 × 2.0 × 0.6 mm body, 0.65 mm pitch, NiPdAu-plated terminals, moisture sensitivity level 1, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; low 194 Ω gate resistance minimizes ringing; ESD-protected per HBM Class 2 |
| 2 (S) | Source | Reference node for gate drive; connected to internal substrate; dual-source pads reduce parasitic inductance |
| 3 (D) | Drain | Main current path; tied to exposed thermal pad (pins 4–6); handles 40 A pulsed drain current |
| 4–6 (D) | Drain (Thermal Pad) | Primary heat dissipation path; requires soldered thermal connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile footprint | 0.6 mm height and 4 mm² area enable use in ultra-thin battery-powered devices |
| Enhanced thermal performance | Exposed drain pad and 8.3 °C/W RθJC allow direct PCB heat sinking without heatsinks |
| Logic-level gate drive | VGS(TH) max = 1.0 V ensures full turn-on from 1.8 V microcontrollers and PMICs |
| Fast switching with low Qgd | Qgd = 1.8 nC limits Miller effect, enabling clean 1–2 MHz operation in buck converters |
| Green compliance | Halogen- and antimony-free, RoHS 3 compliant, <900 ppm Br/Cl, <1000 ppm Sb |

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 |
|---|---|---|---|
| DMN2022LFG-7 | Same die, but in leaded SOT-23-6 package; RθJA = 188 °C/W (no thermal pad); higher profile (1.3 mm) | Less suitable for high-power density layouts; better for prototyping or manual assembly | Select when thermal pad soldering is impractical or legacy board compatibility is required |
| AO3414 | RDS(ON) = 28 mΩ @ 4.5 V; Qg = 8.5 nC; no specified ESD rating; TO-236AB package | Lacks integrated ESD protection; slightly higher conduction loss impacts efficiency in 5 A+ applications | Choose only if cost sensitivity outweighs reliability requirements in non-portable industrial designs |
Compared with DMN2022LFG-7 and AO3414, DMN2022UFDF-13 delivers superior thermal performance via its exposed drain pad, lower RDS(ON), and guaranteed ESD protection-making it optimal for miniaturized, battery-critical systems where efficiency and robustness are co-prioritized.

FAQ
What is the maximum safe operating temperature for DMN2022UFDF-13?
The junction temperature must not exceed +150°C under any operating condition. With RθJA = 60 °C/W and PD = 2.03 W (with 1-inch² copper), ambient temperature must stay below +116°C to maintain safety margin. Derating is required above +70°C ambient per the datasheet's thermal curves.
Does DMN2022UFDF-13 require a gate resistor for stability?
A gate resistor (typically 5–22 Ω) is recommended to dampen ringing caused by gate loop inductance and Ciss/Crss interaction. The 194 Ω intrinsic gate resistance alone is insufficient for clean 1–2 MHz switching; external series resistance improves EMI and prevents shoot-through in half-bridge configurations.
Can DMN2022UFDF-13 be used in automotive applications?
DMN2022UFDF-13 is not AEC-Q101 qualified. While its -55°C to +150°C operating range meets automotive ambient requirements, it lacks PPAP documentation, IATF 16949 manufacturing certification, and stress-test validation for automotive use. Diodes offers AEC-Q101 variants (e.g., DMN2022UFDFQ) for qualified applications.
How does the U-DFN2020-6 thermal pad affect PCB layout?
The exposed drain pad (pins 4–6) must be fully soldered to a minimum 1-inch² copper pour connected to system ground. Thermal vias (≥6×0.3 mm) beneath the pad are strongly recommended to transfer heat to inner layers. Inadequate pad connection raises RθJA from 60 to 188 °C/W, risking thermal shutdown at >1.3 W dissipation.
