Product details
Overview
DMN3016LFDFQ-7 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in a U-DFN2020-6 (Type F) package, rated for 30V VDSS, 12 mΩ RDS(ON) @ 10VGS, and 10A continuous drain current at 25°C. It serves as a high-efficiency power switch in automotive battery management and DC-DC converter primary-side switching stages.
For engineers reviewing the DMN3016LFDFQ-7 datasheet, DMN3016LFDFQ-7 pinout, DMN3016LFDFQ-7 application, or DMN3016LFDFQ-7 equivalent, this page delivers verified electrical parameters, thermal performance under FR-4 PCB mounting, gate charge characteristics, and AEC-Q101 compliance context for automotive-grade design validation.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching with Qg = 25.1 nC @ 10VGS. Its 1.4–2.0 V gate threshold enables robust turn-on with standard 3.3V/5V logic-level drivers in automotive power rails.
Thermal design is constrained by RθJA = 66 °C/W (with 1-inch² copper pad) and RθJC = 11.6 °C/W, supporting operation up to +150°C junction temperature. The integrated body diode exhibits VSD = 0.70–1.0 V @ 1A, suitable for synchronous rectification and freewheeling in buck converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 12V automotive system rail switching |
| RDS(ON) @ 10VGS | 12 mΩ - Enables ≤1.2 W conduction loss at 10A, critical for thermally constrained modules |
| RDS(ON) @ 4.5VGS | 16 mΩ - Ensures reliable turn-on with 5V gate drivers in battery management ICs |
| Qg @ 10VGS | 25.1 nC - Determines gate drive power and switching transition time in 200–500 kHz DC-DC designs |
| tR/tF | 16.5 ns / 5.6 ns - Supports high-frequency operation while limiting EMI generation in compact converters |
| TJ Range | −55°C to +150°C - Validated for under-hood automotive environments per AEC-Q101 stress testing |
| PD (1″² Cu) | 2.02 W - Sets maximum steady-state power handling on standard production PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BSC014N04LS6 | 40V VDSS, 1.4 mΩ RDS(ON) @ 10VGS, PG-TSDSON-8 package (3.3 × 3.3 mm) | Higher voltage rating and lower RDS(ON), but larger footprint and higher gate charge (34 nC) | Select when 40V headroom or <1 mΩ conduction loss is required; verify layout compatibility with larger package |
| ON Semiconductor NTMFS4C09NT1G | 30V VDSS, 9.5 mΩ RDS(ON) @ 10VGS, 2×2 mm WDFN package, Qg = 22.5 nC | Slightly lower RDS(ON) and gate charge, same footprint, but qualified to AEC-Q101 Grade 0 (−40°C to +175°C) | Prefer for extended temperature range needs; verify PPAP documentation alignment with Tier-1 requirements |

FAQ
What is the maximum continuous drain current for DMN3016LFDFQ-7 at 70°C ambient?
The maximum continuous drain current is 8 A at TA = +70°C with standard FR-4 PCB mounting (2 oz copper, minimum pad layout). With a 1-inch² copper pad, it increases to 9 A under the same ambient condition, as specified in the Absolute Maximum Ratings table (Note 6).
Is DMN3016LFDFQ-7 suitable for synchronous rectification in a 500 kHz buck converter?
Yes. With tR = 16.5 ns and tF = 5.6 ns, plus Qg = 25.1 nC @ 10VGS, it supports clean switching at 500 kHz when paired with a 1–2 Ω gate resistor and adequate gate drive strength (≥2 A peak). Layout must minimize source inductance to avoid shoot-through.
Does DMN3016LFDFQ-7 have avalanche capability, and what is its rated energy?
Yes. It is rated for 22 A avalanche current (IAR) with L = 0.1 mH and 24 mJ avalanche energy (EAR) under the same inductive test condition, confirming ruggedness against inductive switching transients common in automotive motor and solenoid drives.
How does the U-DFN2020-6 (Type F) package affect thermal performance compared to SO-8?
The U-DFN2020-6 achieves RθJA = 66 °C/W with a 1-inch² copper pad-significantly better than typical SO-8 (≈100 °C/W)-due to direct die-to-PCB thermal path via exposed drain pads. However, solder joint reliability requires strict reflow profiling to prevent voiding in the thermal pad.
