Product details
Overview
DMT3020LFVW-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in PowerDI3333-8 (SWP) package, delivering 17mΩ RDS(ON) at VGS = 10V, 38A continuous drain current at TC = +25°C, and wettable flank terminals for automated optical inspection-used in high-density power management and analog switching circuits.
For engineers reviewing the DMT3020LFVW-7 datasheet, DMT3020LFVW-7 pinout, DMT3020LFVW-7 application, or DMT3020LFVW-7 equivalent, key selection criteria include low on-resistance at 4.5V gate drive, thermal resistance of 4.0°C/W junction-to-case, and compatibility with compact board layouts requiring <33% area vs. SO-8.
Technical Context
This MOSFET employs planar trench-gate silicon technology optimized for simultaneous low RDS(ON) and fast switching, with 7.0nC total gate charge at VGS = 10V and 3.6nC at 4.5V. Its body diode exhibits 0.8–1.2V forward voltage at 2A, supporting synchronous rectification and bidirectional current paths.
Thermal design is enabled by a 4.0°C/W RθJC and dual thermal dissipation modes: 1.0W on standard FR-4 (RθJA = 124°C/W) and 2.0W with 1-inch² copper pad (RθJA = 62°C/W), validated per JESD51-14 for transient thermal impedance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage before avalanche onset; supports 24V rail systems with margin. |
| RDS(ON) | 17mΩ @ VGS = 10V - Enables ≤0.6W conduction loss at 9A; critical for efficiency in DC-DC converters. |
| ID (continuous) | 38A @ TC = +25°C - Sustains high-current load switching when mounted on thermally enhanced PCBs. |
| Qg | 7.0nC @ VGS = 10V - Determines gate driver sizing and switching loss in hard-switched topologies. |
| RθJC | 4.0°C/W - Enables direct heatsink attachment via exposed drain pad; simplifies thermal path in power stages. |
| VGS(TH) | 1.0–2.5V - Ensures reliable turn-on with 3.3V logic-level gate drivers without level-shifting. |
| Ciss | 393pF - Influences Miller effect and gate drive stability in high-frequency PWM applications. |
Pinout & Package
Package: PowerDI3333-8 (SWP) (Type UX), surface-mount, thermally enhanced with wettable flank leads and exposed drain paddle for solder joint inspection and heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Drain, Pins 1–4) | Main current path output terminal | Internally connected to exposed copper paddle; primary thermal and electrical return path to PCB ground plane. |
| G (Gate, Pin 5) | Control input for channel conduction | Low-impedance input requiring <7.0nC charge; sensitive to ESD but compatible with 3.3V/5V microcontroller outputs. |
| S (Source, Pins 6–8) | Reference node for gate drive and current sensing | Provides Kelvin connection for accurate current monitoring; pins 6–8 are internally shorted for low-inductance return. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 4.5V | 28mΩ - Enables efficient operation directly from 5V buck converter outputs without gate boosting. |
| Wettable flank leads | Full side-wall tin plating - Allows AOI verification of solder fillet height and void detection on production lines. |
| Small footprint | 3.3mm × 3.3mm - Occupies only 33% board area of SO-8, enabling higher power density in space-constrained modules. |
| Lead-free & green | <900ppm Br+Cl, <1000ppm Sb - Complies with RoHS 3 and automotive halogen-free requirements without compromising reliability. |
| High pulse current rating | IDM = 40A (380μs, 1%) - Supports motor startup surges and inrush limiting in industrial actuators. |
Applications
| DC-DC Converter High-Side Switch | USB Type-C Power Delivery Switch |
|---|---|

IC Role / Device Role / Timing Role: Precision current path controlled by DAC-driven gate voltage; switches at 20kHz with <10ns rise/fall times. Use Value: 1.9ns tR and 2.4ns tF minimize PWM dead-time distortion, preserving color fidelity across brightness levels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3020LSD-7 | Same die, SO-8 package - larger footprint, no wettable flanks, RθJA = 62°C/W on 1″² copper. | Preferred where legacy SO-8 tooling exists and AOI is not required; lower thermal performance in dense layouts. | Select when board rework capability is prioritized over miniaturization and automated inspection. |
| DMN3020LFG-7 | Same RDS(ON), PowerDI3333-8 but non-wettable flank variant - lacks side-wall plating for AOI. | Suitable for cost-sensitive consumer applications where optical inspection is not mandated by quality plan. | Choose when RoHS/green compliance is required but AOI traceability is not enforced in manufacturing. |
Compared with DMT3020LFVW-7, DMT3020LSD-7 trades board area and inspection capability for broader package compatibility, while DMT3020LFG-7 reduces cost by omitting wettable flanks-neither matches its combination of miniaturization, thermal efficiency, and process-verifiable solder joints.

FAQ
What is the maximum safe operating temperature for DMT3020LFVW-7?
The junction temperature must not exceed +150°C under any operating condition. Derating begins at +25°C ambient for the 1.0W FR-4 configuration (124°C/W RθJA) and at +88°C ambient for the 2.0W copper-plate configuration (62°C/W RθJA). Thermal shutdown is not integrated; external monitoring is required.
Can DMT3020LFVW-7 be used with 3.3V logic-level gate drive?
Yes-its VGS(TH) range of 1.0–2.5V ensures turn-on with 3.3V drive, though RDS(ON) rises to 28mΩ at VGS = 4.5V. For optimal efficiency, use a gate driver capable of 5–10V swing; 3.3V operation is viable for low-duty-cycle or low-current applications.
Does DMT3020LFVW-7 require a gate resistor for stability?
A series gate resistor (typically 5–22Ω) is recommended to dampen ringing caused by Lg–Ciss resonance, especially at >200kHz switching. The 1.1Ω intrinsic gate resistance is insufficient alone; external Rg also controls dV/dt and EMI in hard-switched topologies.
How does the wettable flank feature improve manufacturing yield?
Wettable flanks provide full-height solder coverage on all four side walls of each lead, enabling automated optical inspection (AOI) to verify fillet formation, solder volume, and void presence-reducing field failures from head-in-pillow or insufficient wetting in fine-pitch SMT processes.
