Product details
Overview
DMT3020LFDFQ-13 from Diodes Incorporated is an AEC-Q101 qualified 30V N-channel enhancement-mode MOSFET in a U-DFN2020-6 (Type F) package, delivering 17 mΩ RDS(ON) at VGS = 10 V and 8.4 A continuous drain current at TA = +25°C. It serves as a low-profile power switch in automotive power management and interfacing circuits.
For engineers reviewing the DMT3020LFDFQ-13 datasheet, DMT3020LFDFQ-13 pinout, DMT3020LFDFQ-13 application, or DMT3020LFDFQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, 0.6 mm profile, 4 mm² PCB footprint, low gate threshold voltage (1.0–2.5 V), and dual RDS(ON) ratings at 4.5 V and 10 V drive levels.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in 12 V automotive systems. Its gate threshold voltage range (1.0–2.5 V) enables reliable turn-on with standard 3.3 V and 5 V logic-level drivers, while its 27 pF Crss supports stable operation in high-frequency load-switching applications.
The device integrates a body diode with 2 A continuous forward current rating and 10 ns reverse recovery time, enabling synchronous rectification and flyback energy handling in compact DC/DC converters. Thermal resistance of 70 °C/W (with 1-inch² copper pad) ensures robust thermal performance under sustained 6.8 A loads at 4.5 V gate drive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Supports 12 V automotive rail with ≥2× voltage margin against transients. |
| RDS(ON) @ 10 V | 17 mΩ max - Enables ≤1.4 W conduction loss at 8.4 A, critical for thermally constrained modules. |
| RDS(ON) @ 4.5 V | 28 mΩ max - Ensures functional switching with 3.3 V microcontroller GPIOs without level-shifting. |
| ID (TA = 25°C) | 6.8 A @ 4.5 V - Sustains full-rated current in logic-level driven automotive body control units. |
| Qg @ 10 V | 7.0 nC - Low gate charge reduces driver power and enables <10 ns turn-on delay with 6 Ω gate resistor. |
| TJ Range | −55 to +150 °C - Meets extended temperature requirements for under-hood and infotainment applications. |
| Package | U-DFN2020-6 (Type F) - 2.0 × 2.0 × 0.6 mm footprint with exposed drain pad for thermal relief. |
Pinout & Package
U-DFN2020-6 (Type F) is a 6-terminal, lead-free, halogen-free surface-mount package with an exposed drain pad (Pin 6) for enhanced thermal dissipation. The 0.6 mm profile and 4 mm² area support ultra-thin automotive modules.

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-13 | Same die, but in SOT-23-3 package; higher RθJA (220 °C/W) and no exposed drain pad. | Limited to ≤2 A continuous current; unsuitable for high-power BCM or LED drivers. | Select only when board space permits larger footprint and thermal budget allows >2× conduction loss. |
| DMTH3010LPSQ-13 | 30 V, 10 mΩ @ 10 V, 12 A ID, in PowerDI5060 package; higher current rating but 1.1 mm profile. | Better for >8 A loads but requires 3× PCB area and lacks MSL Level 1 moisture rating. | Choose when peak current exceeds 8.4 A and thermal mass can accommodate thicker profile. |
Compared with DMT3020LFDFQ-13, DMT3020LSDQ-13 trades thermal performance for legacy through-hole compatibility, while DMTH3010LPSQ-13 prioritizes current density over footprint and moisture resilience-making the DMT3020LFDFQ-13 optimal for space- and reliability-critical automotive modules.

FAQ
Is DMT3020LFDFQ-13 suitable for hot-swap applications?
Yes. Its 30 V VDSS, 40 A pulsed drain rating, and 11.4 A avalanche current support controlled inrush limiting in 12 V hot-swap circuits. The 1.0–2.5 V gate threshold enables precise soft-start via RC gate bias, and the 0.6 mm profile fits tight connector-side layouts without compromising thermal derating.
What is the maximum PCB copper area needed to achieve the 70 °C/W RθJA rating?
The 70 °C/W thermal resistance is measured on FR-4 with a 1-inch square (25.4 mm × 25.4 mm) 2 oz copper pad connected to the exposed drain pad (Pin 6). Smaller copper areas increase thermal resistance linearly; a 10 mm × 10 mm pad yields ~140 °C/W, requiring derating to ≤3.5 A at 4.5 V drive.
Does this MOSFET require a gate resistor for stability in automotive environments?
Yes. A 6 Ω gate resistor is specified in the datasheet for switching characterization and suppresses oscillation caused by PCB trace inductance and gate capacitance (393 pF Ciss). In CAN/LIN noise-prone environments, a 10 Ω resistor further dampens EMI while maintaining <2 ns rise time at 6.8 A load.
Can DMT3020LFDFQ-13 replace older SOT-23 MOSFETs in existing designs?
Only with layout revision. Its U-DFN2020-6 footprint is incompatible with SOT-23 pads, and the exposed drain pad must be soldered to a dedicated thermal copper pour. Electrical replacement is valid-same VDSS, VGS(TH), and RDS(ON) specs-but mechanical redesign and requalification per AEC-Q101 are required.
