Product details
Overview
DMT3020LFDF-13 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type F) package, delivering 17mΩ RDS(ON) at VGS = 10V and 8.4A continuous drain current at TA = +25°C. It serves as a low-profile power switch in compact DC-DC converters and load-switching circuits where thermal efficiency and PCB space are constrained.
For engineers reviewing the DMT3020LFDF-13 datasheet, DMT3020LFDF-13 pinout, DMT3020LFDF-13 application, or DMT3020LFDF-13 equivalent, key selection criteria include its 17mΩ/28mΩ dual RDS(ON) spec at 10V/4.5V, 0.6mm profile, 4mm² footprint, and AEC-Q101 readiness for automotive-grade power management.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low on-resistance while preserving fast switching performance-evidenced by 7.0nC total gate charge at VGS = 10V and 1.9ns rise time. Its body diode exhibits 1.2V forward voltage at 2A, supporting synchronous rectification and reverse-current blocking in buck converters.
The device operates across –55°C to +150°C junction temperature range with normalized RDS(ON) variation under 1.8× from –55°C to +150°C at VGS = 10V. Thermal resistance RθJA is 70°C/W when mounted on FR-4 with 1-inch² copper pad-critical for thermally constrained portable and automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum drain-source blocking voltage; suitable for 24V rail and 12V automotive systems with margin. |
| RDS(ON) max | 17mΩ @ VGS = 10V - Enables <150mW conduction loss at 8.4A; critical for high-efficiency load switches. |
| ID max | 8.4A @ TA = +25°C - Supports medium-power DC-DC output stages and battery protection circuits. |
| Qg | 7.0nC @ VGS = 10V - Low gate drive energy reduces driver IC loading and switching losses in 500kHz–1MHz SMPS. |
| RθJA | 70°C/W - Achievable with 1-inch² copper pad; enables 1.1W dissipation at TA = +70°C without heatsink. |
| VGS(TH) | 1.0–2.5V - Ensures reliable turn-on with 3.3V logic-level gate drivers; avoids partial-enhancement in low-voltage control. |
Pinout & Package
U-DFN2020-6 (Type F) package: 2.0mm × 2.0mm × 0.6mm, molded green plastic, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce bond-wire inductance and improve current sharing in high-di/dt applications. |
| 4 | Gate (G) | Single gate input with 1.1Ω gate resistance-enables stable PWM control without external gate resistor in most 1MHz designs. |
| 5, 6 | Drain (D) | Two drain terminals connected to exposed thermal pad; primary path for power dissipation and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| 0.6mm profile | Enables integration into ultra-thin consumer electronics (e.g., wearables, slim power banks) where height ≤0.7mm is mandatory. |
| 4mm² PCB footprint | Reduces board area by >40% vs. SO-8; supports dense multi-rail PMIC layouts in space-constrained IoT edge nodes. |
| Low VGS(TH) | Guarantees full enhancement with 3.3V microcontroller GPIOs-eliminates need for level-shifting or dedicated gate drivers. |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and JEDEC J-STD-020 Level 1-supports automated reflow without moisture-related popcorning. |

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 |
|---|---|---|---|
| DMN3020LFG-7 | Same U-DFN2020-6 package but rated for 30V/7.5A; RDS(ON) = 20mΩ @ 4.5V (vs. 28mΩ), higher Qg = 8.5nC. | Better suited for lower-frequency (<300kHz), higher-current loads where gate drive strength exceeds requirement. | Select when prioritizing lower RDS(ON) over switching speed; verify gate driver can supply 8.5nC without overshoot. |
| Si2302DDS-T1-GE3 | 20V-rated SOT-23 device; RDS(ON) = 35mΩ @ 4.5V, 3.2A ID; smaller die but no avalanche rating. | Limited to 5V–12V logic-level systems; unsuitable for 24V automotive or industrial rails due to VDSS margin. | Choose only for cost-sensitive, low-power 3.3V/5V logic interfaces-not for power conversion or automotive use. |
Compared with DMT3020LFDF-13, DMN3020LFG-7 offers tighter RDS(ON) tolerance at 4.5V but sacrifices switching speed, while Si2302DDS-T1-GE3 lacks voltage headroom and ruggedness for industrial environments-making DMT3020LFDF-13 the optimal balance of size, efficiency, and reliability in 24V-class compact power switches.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The DMT3020LFDF-13 has an absolute maximum junction temperature of +150°C. Continuous operation at this limit requires thermal design ensuring RθJA ≤ 70°C/W with a 1-inch² copper pad, as verified in Note 6 of the datasheet. Derating is required above +70°C ambient to maintain safe operating area compliance.
Does this MOSFET require a gate resistor for standard PWM switching?
No external gate resistor is required for typical 500kHz–1MHz PWM operation due to its intrinsic 1.1Ω gate resistance and low 7.0nC gate charge. However, a 2–5Ω series resistor is recommended when driving from high-impedance sources or to damp ringing in high-di/dt layouts with long gate traces.
Is the U-DFN2020-6 (Type F) package compatible with standard reflow profiles?
Yes-the device is moisture sensitivity level 1 per J-STD-020 and fully RoHS-compliant, supporting standard lead-free reflow profiles (peak 260°C). The NiPdAu finish ensures solderability per MIL-STD-202, Method 208, and the green molding compound meets UL 94V-0 flammability rating.
Can DMT3020LFDF-13 be used in linear-regulator mode?
No-it is not characterized or rated for linear (ohmic) operation. The Safe Operating Area (SOA) curve (Figure 12) shows DC limitation only up to ~1.5A at VDS = 10V, and thermal runaway risk increases rapidly outside pulsed conditions. Use only in saturated switching mode.
