Product details
Overview
DMT3020LFDFQ-7 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET with 30V VDSS, 17mΩ RDS(ON) @ 10V VGS, and 8.4A ID at +25°C - designed for automotive power management and low-profile switching in space-constrained PCBs.
For engineers reviewing the DMT3020LFDFQ-7 datasheet, DMT3020LFDFQ-7 pinout, DMT3020LFDFQ-7 application, or DMT3020LFDFQ-7 equivalent, key selection criteria include its U-DFN2020-6 (Type F) package, 0.6mm profile, low gate threshold (1.0–2.5V), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in 12V automotive systems. Its 4.5V-rated on-resistance (28mΩ max) supports direct drive from microcontroller GPIOs without level-shifting.
The device integrates a body diode with 1.2V forward voltage at 2A and exhibits 6.5mJ avalanche energy (L = 0.1mH), enabling robust operation under inductive load switching and transient overvoltage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Supports 12V automotive rail with 2.5× safety margin against load-dump transients. |
| RDS(ON) @ 10V | 17mΩ max - Enables ≤1.4W conduction loss at 8.4A, suitable for continuous high-current switching. |
| RDS(ON) @ 4.5V | 28mΩ max - Ensures reliable turn-on with standard 3.3V/5V logic-level drivers. |
| Qg @ 10V | 7.0nC - Low gate charge reduces drive power and enables <10ns turn-on delay with 6Ω gate resistor. |
| TJ Range | −55°C to +150°C - Validated for under-hood environments including engine control modules and ADAS power stages. |
| PD (with 1″² copper) | 1.8W - Allows 6.8A continuous current at +70°C ambient when using recommended thermal pad layout. |
Pinout & Package
Package: U-DFN2020-6 (Type F), 2.0mm × 2.0mm × 0.6mm, 6-terminal leadless plastic package with NiPdAu-plated terminals and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal (S) | Primary current return path; electrically tied to exposed thermal pad for enhanced heat dissipation. |
| 2 (Gate) | Gate terminal (G) | Control input; low 1.0–2.5V threshold enables direct MCU interface without external level shifters. |
| 3 (Drain) | Drain terminal (D) | High-side or low-side switch node; connected to internal die drain metallization and top-side metal pad. |
| 4 (Source) | Source terminal (S) | Second source connection - paralleled internally with Pin 1 to reduce source inductance and improve switching stability. |
| 5 (Drain) | Drain terminal (D) | Second drain connection - paralleled internally with Pin 3 to minimize channel resistance and dynamic losses. |
| 6 (Thermal Pad) | Exposed thermal pad | Non-electrical mechanical anchor and thermal path; must be soldered to PCB copper pour for RθJA = 70°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications per stress test requirements including HTOL, TC, HAST, and ESD-HBM ≥2kV. |
| 0.6mm profile | Enables use in ultra-thin modules such as camera ECU housings and compact ADAS sensor assemblies. |
| PCB footprint: 4mm² | Reduces board area by >50% vs. SO-8 equivalents while maintaining comparable current handling and thermal performance. |
| Low RDS(ON) temperature coefficient | RDS(ON) increases only ~1.4× from −55°C to +150°C at VGS = 10V, ensuring stable conduction across full automotive temperature range. |
| Halogen- and antimony-free "Green" | Meets JESD201A Class 1A whisker resistance and EU RoHS 3 (2015/863/EU) with Br+Cl <1500ppm and Sb <1000ppm. |

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 |
|---|---|---|---|
| DMT3020LSDQ-7 | Same die, but in SOT-23-6 package - larger footprint (3.0mm × 2.8mm), higher RθJA = 180°C/W, no thermal pad. | Limited to lower-power applications (<2W dissipation); unsuitable for sustained >4A loads in sealed enclosures. | Select only if legacy SOT-23 layout reuse is required and thermal budget permits higher junction rise. |
| DMTH3010LPSQ-13 | Higher VDSS (40V), lower RDS(ON) (10.5mΩ @ 10V), larger U-DFN2030-6 package (2.0mm × 3.0mm). | Better suited for 24V commercial vehicle systems; requires revised PCB land pattern and increased board area. | Choose when upgrading to 24V architecture or requiring >10A continuous current with improved thermal margin. |
Compared with DMT3020LFDFQ-7, DMT3020LSDQ-7 trades thermal performance for package compatibility, while DMTH3010LPSQ-13 offers higher voltage headroom and lower conduction loss at the cost of larger size - making the DMT3020LFDFQ-7 optimal for cost- and space-sensitive 12V automotive switches.

FAQ
Is DMT3020LFDFQ-7 suitable for hot-swap applications?
Yes - its 30V VDSS, 40A pulsed drain rating, and 6.5mJ avalanche energy make it appropriate for controlled hot-swap insertion in 12V automotive sub-systems. The low 1.0–2.5V gate threshold allows predictable turn-on during ramp-up, and the U-DFN2020-6 thermal pad helps manage transient power dissipation during inrush events.
What is the maximum PCB copper area needed to achieve RθJA = 70°C/W?
A 1-inch square (25.4mm × 25.4mm) copper pour on the top layer, connected to the exposed thermal pad via ≥4 thermal vias (0.3mm diameter, filled), achieves the specified 70°C/W thermal resistance. Smaller pads increase RθJA linearly - e.g., 0.5-inch square raises it to ~110°C/W per datasheet Note 6.
Does DMT3020LFDFQ-7 require gate resistors for EMI control?
Yes - although its 1.1Ω intrinsic gate resistance limits ringing, a 5–10Ω series gate resistor is recommended to dampen high-frequency oscillations during fast switching (tR/tF < 3ns). This improves EMI compliance in CISPR 25 Class 5 automotive environments without compromising turn-on delay beyond 2.5ns.
Can this MOSFET replace older TO-252 devices in existing designs?
No - the U-DFN2020-6 package is not pin-compatible with TO-252 (DPAK) or SO-8 footprints. Direct replacement requires PCB redesign to accommodate the 2.0mm × 2.0mm layout, thermal pad soldering, and revised gate drive routing. However, its electrical specs allow functional equivalence in new 12V automotive power stages where miniaturization is critical.
