Product details
Overview
DMT3020LFCL-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in a U-DFN1616-6 (Type K) package, optimized for low RDS(ON) (20 mΩ @ VGS = 10 V) and high-efficiency load switching. It delivers 7.6 A continuous drain current at 25°C and supports thin-profile power management in space-constrained portable electronics.
For engineers reviewing the DMT3020LFCL-7 datasheet, DMT3020LFCL-7 pinout, DMT3020LFCL-7 application, or DMT3020LFCL-7 equivalent, key selection criteria include its 0.6 mm profile, 2.56 mm² PCB footprint, thermal resistance (RθJA = 73 °C/W with copper plate), body diode forward voltage (0.78 V), and gate charge (3.6 nC @ 4.5 V).
Technical Context
This MOSFET employs a trench-gate process to achieve low on-resistance while maintaining fast switching performance-evidenced by tD(ON) = 1.8 ns and QG = 3.6 nC at 4.5 V. Its VGS(TH) range (1.0–3.0 V) ensures reliable turn-on with standard logic-level drivers.
The device integrates a robust body diode (tRR = 10 ns, QRR = 2.6 nC) and operates across –55°C to +150°C. Thermal design is supported by two RθJA ratings: 207 °C/W (minimal pad) and 73 °C/W (1-inch² copper plate), enabling flexible layout trade-offs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage before avalanche conduction begins |
| RDS(ON) | 20 mΩ @ VGS = 10 V - Enables <150 mW conduction loss at 7.6 A |
| ID (max) | 7.6 A @ TA = 25°C - Continuous current capability with recommended PCB copper area |
| QG | 3.6 nC @ VGS = 4.5 V - Low gate drive energy reduces switching losses in battery-powered systems |
| VGS(TH) | 1.6 V (typ) - Ensures full enhancement with 3.3 V or higher logic-level gate drive |
| tRR | 10 ns - Fast body diode recovery minimizes shoot-through risk in synchronous buck topologies |
| RθJA | 73 °C/W - Achievable with 1-inch² 2 oz copper pad; enables 1.7 W power dissipation at ambient |

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 |
|---|---|---|---|
| DMN3020LFG-7 | Same die, but in SOT-23-6 package; RDS(ON) = 20 mΩ @ 10 V, but RθJA = 195 °C/W (no thermal pad) | Larger footprint (2.9 mm × 2.8 mm), unsuitable for ultra-thin designs; better for manual assembly or prototyping | Select when thermal pad soldering is not feasible or when legacy SOT-23 layout reuse is prioritized |
| AO3414 | 30 V, 5.7 A, RDS(ON) = 33 mΩ @ 4.5 V; SO-8 package; higher RθJA (125 °C/W) | Higher conduction loss at 6 A (>200 mW vs. ~115 mW), requires larger board area and heatsinking | Choose only if U-DFN reflow capability is unavailable or if SO-8 mechanical robustness is mandatory |
Compared with DMN3020LFG-7 and AO3414, DMT3020LFCL-7 delivers superior thermal performance (73 °C/W), smallest form factor (1.6 mm × 1.6 mm), and lowest gate charge for logic-level drive-making it optimal for production-scale, space- and efficiency-critical portable power switches.

FAQ
What is the maximum allowable gate-source voltage for DMT3020LFCL-7?
The absolute maximum VGS rating is ±20 V per the datasheet. Operation beyond ±12 V risks gate oxide degradation, especially at elevated temperatures. For robust long-term reliability, keep VGS ≤ ±10 V in normal use, matching the specified RDS(ON) test condition.
Does DMT3020LFCL-7 require a gate resistor for typical load-switch applications?
No external gate resistor is required for basic ON/OFF switching at frequencies below 1 MHz. The device's low QG (3.6 nC @ 4.5 V) and integrated gate resistance (RG = 1.1 Ω) allow direct GPIO drive. A 10–100 Ω series resistor may be added only to damp ringing in high-dI/dt layouts or EMI-sensitive environments.
Can DMT3020LFCL-7 be used in reverse conduction mode (source-to-drain current)?
Yes-the integrated body diode supports continuous forward current up to 2 A (IS) and pulsed current up to 40 A (IDM). Its VSD = 0.78 V (typ) at 2 A and tRR = 10 ns make it suitable for bidirectional power path applications like charging case handshaking, provided thermal limits are observed.
Is the thermal pad on the bottom of DMT3020LFCL-7 electrically connected?
Yes-the exposed thermal pad is internally connected to the drain (D) terminals (Pins 3, 5, and 6). It must be soldered to a PCB copper pour tied to the drain net to ensure both thermal performance and electrical integrity. Floating or grounded pads will impair thermal dissipation and may cause malfunction.
