Product details
Overview
DMT3020LFDB-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in a U-DFN2020-6 (Type B) package, rated for 30V VDSS, 20 mΩ RDS(ON) @ VGS = 10 V, and 7.7 A continuous drain current at TA = +25°C. It delivers low-profile power switching in space-constrained DC-DC converters and load-switching circuits.
For engineers reviewing the DMT3020LFDB-7 datasheet, DMT3020LFDB-7 pinout, DMT3020LFDB-7 application, or DMT3020LFDB-7 equivalent, key selection criteria include its dual-channel layout, 0.6 mm profile, AEC-Q101 qualification, gate threshold voltage range (1.0–2.5 V), and thermal resistance of 70 °C/W under enhanced PCB layout conditions.
Technical Context
This dual MOSFET integrates two matched N-channel devices sharing no internal connection-each channel operates independently with separate gate, source, and drain terminals. Its design emphasizes low RDS(ON) at both 4.5 V and 10 V drive, enabling compatibility with 3.3 V and 5 V logic-level control.
The device uses a trench-gate process to achieve high transconductance and fast switching (tD(ON) = 1.8 ns, tD(OFF) = 7.5 ns) while maintaining low gate charge (QG = 3.6 nC @ 4.5 V). Body diode recovery is characterized with tRR = 10 ns and QRR = 2.6 nC under defined di/dt conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum drain-source blocking voltage before avalanche conduction begins. |
| RDS(ON) @ VGS = 10 V | 20 mΩ - Enables <150 mW conduction loss at 7.7 A, critical for high-efficiency buck converter high-side switches. |
| RDS(ON) @ VGS = 4.5 V | 32 mΩ - Supports direct interfacing with 3.3 V microcontroller GPIO without level-shifting. |
| QG @ VGS = 4.5 V | 3.6 nC - Low gate charge reduces driver power demand and enables >1 MHz switching in compact power stages. |
| TJ Range | −55°C to +150°C - Qualified per AEC-Q101, suitable for under-hood automotive and industrial ambient environments. |
| RθJA (enhanced layout) | 70 °C/W - Achieved with 1-inch² copper pad; determines maximum sustainable power dissipation (1.8 W) in thermally optimized PCBs. |
Pinout & Package
Package: U-DFN2020-6 (Type B), 2.0 mm × 2.0 mm × 0.6 mm, NiPdAu-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-current output node; electrically isolated from D2; connects to input rail in high-side switch configuration. |
| S1 | Source of Channel 1 | Reference node for Channel 1; tied to ground or load return; shares no internal connection with S2. |
| G1 | Gate of Channel 1 | Control terminal for Channel 1; requires ≤2.5 V threshold for turn-on; decoupling capacitor recommended near IC. |
| D2 | Drain of Channel 2 | Independent high-current output node; supports dual-load or half-bridge topologies with external bootstrap. |
| S2 | Source of Channel 2 | Reference node for Channel 2; may be floated in high-side applications; not internally connected to S1. |
| G2 | Gate of Channel 2 | Independent control terminal; identical electrical characteristics to G1; enables synchronous dual-channel timing. |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-supports infotainment and body control modules. |
| Low VGS(TH) (1.0–2.5 V) | Ensures full enhancement with standard 3.3 V logic outputs; eliminates need for gate drivers in low-power load-switching applications. |
| Green compound (halogen/antimony-free) | Meets IPC-1752A Class 1 reporting requirements and supports RoHS 3 (2015/863/EU) compliance for global market access. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3020LFG-7 | Same die, but in SOT-23-6 package; RθJA = 170 °C/W (no thermal pad); 0.95 mm height. | Lower power density (max 0.7 W); unsuitable for >3 A continuous loads without forced air. | Select when board space allows larger footprint and thermal performance is secondary to cost. |
| AOB410L | Single-channel 30 V MOSFET in TO-252; RDS(ON) = 18 mΩ @ 10 V; QG = 10.5 nC; RθJA = 60 °C/W. | Requires two discrete devices for dual functionality; higher gate drive energy; better thermal dissipation. | Select when higher current (>10 A/channel) or superior thermal management is required, and board area permits TO-252 layout. |
Compared with DMT3020LFDB-7, DMN3020LFG-7 trades thermal capability for lower assembly cost and simpler reflow, while AOB410L offers higher current handling at the expense of integration density and gate drive efficiency.

FAQ
Is DMT3020LFDB-7 suitable for hot-swap applications?
Yes. Its 30 V VDSS, low RDS(ON), and fast switching (tF = 2.4 ns) support controlled inrush limiting in hot-swap circuits. The dual-channel architecture allows independent enable control for redundant power paths, and its AEC-Q101 qualification confirms robustness against transient overstress events typical in live-insertion scenarios.
What is the maximum safe operating current at 85°C ambient?
At TA = 85°C with the enhanced 1-inch² copper layout (RθJA = 70 °C/W), the maximum continuous drain current per channel is 6.2 A. This is derived from the derating curve in the datasheet and assumes TJ(max) = 150°C, yielding ΔT = 65°C and allowable power dissipation of 0.93 W, consistent with the 32 mΩ RDS(ON) @ 4.5 V condition.
Does DMT3020LFDB-7 integrate back-to-back MOSFETs for bidirectional blocking?
No. DMT3020LFDB-7 contains two independent N-channel MOSFETs with no internal series or anti-parallel connection. Each channel has separate D, S, and G terminals. For true bidirectional blocking, external circuitry (e.g., series-connected pairs or dedicated bidirectional switches) is required.
Can the body diodes be used for synchronous rectification?
Yes-each channel's intrinsic body diode is characterized with VSD = 1.0 V @ 2 A and tRR = 10 ns, making it usable in low-frequency (<500 kHz) synchronous rectifier designs. However, for high-frequency operation, external Schottky diodes or actively driven synchronous FETs are preferred due to the diode's forward voltage and recovery limitations.
