Product details
Overview
DMT6030LFDF-7 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type F) package, delivering 25.5mΩ RDS(ON) at VGS = 10V and 6.8A continuous drain current at TA = +25°C. It features 100% production-tested UIS robustness, 0.6mm profile, and 4mm² PCB footprint-optimized for compact load switching in notebook PCs and AC/DC adapters.
For engineers reviewing the DMT6030LFDF-7 datasheet, DMT6030LFDF-7 pinout, DMT6030LFDF-7 application, or DMT6030LFDF-7 equivalent, key selection criteria include its low-profile U-DFN2020-6 thermal performance (RθJA = 71°C/W with copper plate), 4.5V logic-level gate drive capability, and validated unclamped inductive switching reliability.
Technical Context
This MOSFET employs planar trench-gate technology to balance low RDS(ON) and fast switching dynamics, with Ciss = 639pF and QG = 9.1nC at VGS = 10V. Its body diode exhibits tRR = 26.5ns and QRR = 12.3nC under 10A/100A/μs conditions, supporting synchronous rectification and flyback topologies.
The device operates across –55°C to +150°C junction temperature range and supports gate voltages up to ±20V. Thermal design leverages its low RθJC = 13°C/W and 1.76W power dissipation on FR-4 with enhanced copper layout-critical for thermally constrained portable power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - Supports input rails up to 48V DC with margin for transient spikes in adapter and load-switch applications. |
| RDS(ON) | 25.5mΩ @ VGS = 10V - Enables <170mW conduction loss at 6.8A, reducing thermal stress in high-current paths. |
| ID (max) | 6.8A @ TA = +25°C - Sustains full-rated current in ambient-cooled notebook power rails without forced airflow. |
| QG | 9.1nC @ VGS = 10V - Allows efficient 1MHz+ switching with moderate gate driver strength (e.g., TC4427). |
| tRR | 26.5ns - Minimizes reverse recovery losses in secondary-side synchronous rectifiers and buck converters. |
| RθJA | 71°C/W with 1-inch² copper - Enables 1.76W operation at ≤70°C ambient rise, suitable for thin-profile PCBs. |
| UIS Rating | 14.7A / 10.8mJ - Guarantees ruggedness against inductive kickback in hot-swap and load-switch circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN6030LFG-7 | Same die, but in larger U-DFN2030-6 (2.0×3.0mm); RθJA = 85°C/W (FR-4), higher 3.5A ID rating at TA = +70°C. | Better thermal headroom for sustained 5A loads in non-compact designs; unsuitable where 2.0×2.0mm footprint is mandatory. | Select when board space allows larger package and higher ambient temperature derating is required. |
| Si2302DDS-T1-GE3 | 60V, 3.2A ID, 115mΩ RDS(ON) @ 4.5V; SOT-23 package; no UIS rating specified. | Limited to <1W power handling; lacks production UIS validation-unsuitable for inductive load switching or hot-swap. | Only consider for low-current (<2A), non-inductive, cost-sensitive applications where ruggedness is secondary. |
Compared with DMT6030LFDF-7, DMN6030LFG-7 trades footprint compactness for thermal margin, while Si2302DDS-T1-GE3 sacrifices both RDS(ON) and reliability assurance-making DMT6030LFDF-7 the optimal choice for space-constrained, high-reliability load switching.

FAQ
What is the maximum safe operating temperature for DMT6030LFDF-7?
The device supports junction temperatures from –55°C to +150°C. With RθJA = 71°C/W on a 1-inch² copper board, it sustains 1.76W at TA = +70°C (TJ ≈ 150°C). Derating is required above 70°C ambient; full 6.8A current is only rated at TA = +25°C per datasheet conditions.
Can DMT6030LFDF-7 be driven directly by a 3.3V GPIO?
No-its VGS(th) range is 1.0–2.5V, but RDS(ON) rises sharply below 4.5V: 35mΩ at VGS = 4.5V vs. 25.5mΩ at 10V. A 3.3V drive yields >50mΩ, doubling conduction loss. Use a level-shifter or 5V-tolerant gate driver for reliable saturation.
Does DMT6030LFDF-7 require a gate resistor for stability?
A gate resistor (typically 5–22Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 13.1pF) and PCB inductance. Without it, overshoot exceeding ±20V VGS rating may occur during fast switching, risking gate oxide damage.
Is the exposed thermal pad electrically connected to any pin?
Yes-the exposed pad is internally connected to the Source (Pins 1 and 4). It must be soldered to a large copper pour for thermal performance and electrical return. Floating or insulated mounting degrades RθJA by >30% and risks thermal runaway under load.
