Product details
Overview
DMN3020UFDFQ-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type F) package, optimized for high-efficiency power management with RDS(ON) = 19 mΩ @ VGS = 4.5V, 15 A continuous drain current at TC = +25°C, and AEC-Q101 qualification for automotive use.
For engineers reviewing the DMN3020UFDFQ-7 datasheet, DMN3020UFDFQ-7 pinout, DMN3020UFDFQ-7 application, or DMN3020UFDFQ-7 equivalent, this part supports low-voltage, high-current switching in space-constrained battery management and DC-DC converter designs where gate threshold voltage (0.4–1.0 V), fast switching speed (tD(ON) = 4.1 ns), and ESD-protected gate are critical selection criteria.
Technical Context
This MOSFET employs a trench-gate process to achieve ultra-low on-resistance while maintaining robust switching performance. Its low VGS(TH) enables direct drive from 1.8 V and 2.5 V logic, and its integrated gate protection diode suppresses transient-induced gate damage.
The device features a thermally enhanced U-DFN2020-6 package with NiPdAu-plated terminals and 18 °C/W junction-to-case thermal resistance. Its RDS(ON) remains stable across -55°C to +150°C, and it delivers 15 mJ single-pulse avalanche energy (L = 0.1 mH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage in off-state; suitable for 24 V automotive and industrial bus rails. |
| RDS(ON) | 19 mΩ @ VGS = 4.5V - Enables <150 mW conduction loss at 4.5 A, critical for thermally constrained PCB layouts. |
| ID (continuous) | 15 A @ TC = +25°C - Supports high-current load switching without external heatsinking when mounted on 1-inch² copper. |
| Qg | 15 nC @ VGS = 4.5V - Low gate charge reduces driver power demand and improves efficiency in high-frequency PWM operation. |
| tD(ON) | 4.1 ns - Fast turn-on delay minimizes overlap losses in synchronous buck converters operating >1 MHz. |
| VGS(TH) | 0.4–1.0 V - Ensures reliable enhancement-mode turn-on with 1.8 V I/O controllers and low-power microcontrollers. |
| EAS | 15 mJ - Withstands inductive energy spikes in motor gate drivers and solenoid control without failure. |
Pinout & Package
Package: U-DFN2020-6 (Type F), 2.0 mm × 2.0 mm × 0.6 mm profile, exposed thermal pad, RoHS-compliant NiPdAu finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Power return path for drain current | Internally connected to thermal pad; must be soldered to large copper area for thermal management. |
| 2 (Gate) | Control electrode for channel formation | ESD-protected input; requires <1.0 V overdrive for full enhancement at low VGS. |
| 3 (Drain) | Main current-carrying terminal | High-side switch node; rated for 30 V blocking and 40 A pulsed current (IDM). |
| 4 (Source) | Redundant source connection | Parallel path to Pin 1; improves current sharing and reduces package inductance in high-dI/dt applications. |
| 5 (Drain) | Redundant drain connection | Parallel path to Pin 3; lowers RDS(ON) contribution from bond wire resistance. |
| 6 (Source) | Third source terminal | Connects directly to thermal pad; essential for achieving 63 °C/W RθJA with 1-inch² copper. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile U-DFN2020-6 package | 0.6 mm height enables integration into ultra-thin portable electronics and automotive ECUs with strict Z-axis constraints. |
| Gate ESD protection | Integrated diode structure withstands ≥2 kV HBM per JESD22-A114, eliminating need for external gate protection components. |
| Automotive qualification | AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949-certified facilities-validates reliability for safety-critical vehicle subsystems. |
| Halogen- and antimony-free "Green" construction | Meets Diodes' definition: <900 ppm Br, <900 ppm Cl (<1500 ppm total Br+Cl), <1000 ppm Sb-supports global environmental compliance programs. |
| Thermal performance | RθJC = 18 °C/W enables efficient heat transfer to PCB; RθJA drops to 63 °C/W with 1-inch² copper, supporting 2.03 W continuous dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3020LFG-7 | Same die, but in U-DFN2020-6 (Type G) package with different pinout (G-S-D-S-D-S vs. S-G-D-S-D-S); identical RDS(ON), Qg, and ratings. | Requires PCB redesign due to altered terminal assignment; not drop-in compatible despite identical electrical specs. | Select only if legacy board uses Type G footprint or sourcing of Type F is constrained. |
| NTMFS4C02NT1G | Higher RDS(ON) (22 mΩ @ 4.5 V), larger U-DFN2020-6 package (2.0×2.0×0.75 mm), no AEC-Q101 qualification. | Lacks automotive qualification and has 15% higher conduction loss; suitable only for commercial-grade DC-DC converters. | Choose only for non-automotive applications where cost is prioritized over thermal performance and qualification. |
Compared with DMN3020UFDFQ-7, DMN3020LFG-7 demands layout revision for pin compatibility, while NTMFS4C02NT1G trades automotive reliability and lower RDS(ON) for broader commercial availability-making DMN3020UFDFQ-7 optimal for space- and qualification-sensitive automotive power switches.

FAQ
What is the maximum safe operating temperature for DMN3020UFDFQ-7?
The device supports junction temperatures from –55°C to +150°C. Its RDS(ON) increases by ~35% at +150°C versus 25°C (per Figure 6), and thermal derating must follow the SOA curve in Figure 13. For continuous 15 A operation, PCB copper area and airflow must maintain TJ ≤ 135°C to ensure 10-year reliability in automotive applications.
Does DMN3020UFDFQ-7 require an external gate resistor?
A gate resistor is recommended to dampen ringing and limit peak gate current, especially at >500 kHz switching frequencies. With Qg = 15 nC and typical driver output impedance of ~1 Ω, a 5–10 Ω series resistor controls dV/dt and prevents false triggering without significantly impacting tD(ON) or tD(OFF).
Can DMN3020UFDFQ-7 be used in reverse-conduction mode (source-to-drain)?
Yes-the integrated body diode supports continuous 2.2 A source-drain current (IS) at 25°C, with VSD = 0.6–1.2 V at 1 A. However, its reverse recovery time (tRR = 7.1 ns) and charge (QRR = 1.7 nC) are optimized for synchronous rectification, not freewheeling in hard-switched topologies.
Is the thermal pad electrically isolated in U-DFN2020-6 (Type F)?
No-the thermal pad is internally connected to the source terminals (Pins 1, 4, and 6). It must be soldered to a PCB ground or source net with ≥80% coverage to achieve specified RθJA = 63 °C/W. Floating or insulated pads degrade thermal performance and violate JEDEC mounting guidelines.
