Product details
Overview
DMT3020LFDBQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type B) package, rated for 30V VDSS, 20mΩ RDS(ON) @ 10V VGS, and 7.7A ID at +25°C - designed for automotive power management and interfacing switches requiring AEC-Q101 qualification and PPAP support.
For engineers reviewing the DMT3020LFDBQ-13 datasheet, DMT3020LFDBQ-13 pinout, DMT3020LFDBQ-13 application, or DMT3020LFDBQ-13 equivalent, this part delivers verified low-profile switching performance with confirmed thermal resistance (RθJA = 70°C/W on 1-in² copper), dual-channel integration, and automotive-grade reliability under IATF 16949 manufacturing.
Technical Context
This dual MOSFET integrates two matched N-channel devices in a single 2.0mm × 2.0mm U-DFN2020-6 (Type B) package with shared thermal pad and independent gate/drain/source terminals. Its low 1.0–2.5V gate threshold enables direct drive from 3.3V and 5V logic controllers.
It supports pulsed drain currents up to 50A (380μs, 1% duty), features 7.0nC total gate charge at 10V, and exhibits normalized RDS(ON) variation ≤1.8× across –55°C to +150°C junction temperature - critical for engine bay and ADAS power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Supports 24V automotive systems with 25% voltage margin against load dump transients. |
| RDS(ON) | 20mΩ @ VGS = 10V - Enables <150mW conduction loss at 7.7A, reducing thermal stress in compact layouts. |
| ID (max) | 7.7A @ TA = +25°C - Sustains continuous current for high-side/low-side switching in DC-DC converters and motor drivers. |
| Qg | 7.0nC @ VGS = 10V - Allows fast switching with low driver power demand; tF = 2.4ns ensures minimal overlap loss. |
| RθJA | 70°C/W - Achieved with 1-inch² copper pad; enables 1.8W power dissipation without forced cooling in automotive modules. |
| AEC-Q101 | Qualified - Validated for automotive use per stress test requirements including HTGB, HTRB, and ESD ≥2kV HBM. |
Pinout & Package
Package: U-DFN2020-6 (Type B), 0.6mm profile, NiPdAu-plated terminals, moisture sensitivity level 1, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (D1) | Drain of Channel 1 | High-current output node; electrically isolated from D2; connects to load or power rail. |
| Pin 2 (S1) | Source of Channel 1 | Return path for Channel 1; tied to ground or low-side reference; shares thermal pad with S2. |
| Pin 3 (G1) | Gate of Channel 1 | Logic-level control input; 1.0–2.5V VGS(TH) enables direct microcontroller drive. |
| Pin 4 (G2) | Gate of Channel 2 | Independent control input; identical threshold and drive requirements as G1. |
| Pin 5 (S2) | Source of Channel 2 | Return path for Channel 2; internally connected to S1 via thermal pad; common-source configuration supported. |
| Pin 6 (D2) | Drain of Channel 2 | Second high-current output node; fully isolated from D1; supports dual-switch topologies (e.g., half-bridge). |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel integration | Two matched MOSFETs in one 2.0×2.0mm footprint - reduces PCB area by >40% vs. discrete dual-SOIC solutions. |
| Low-profile 0.6mm height | Enables placement under connectors or beneath shields in space-constrained ADAS ECUs and body control modules. |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br+Cl, <1000ppm Sb) - meets Tier-1 automotive material declarations. |
| Thermal pad design | Exposed thermal pad (Pin #1 ID) provides primary heat path to PCB - achieves RθJA = 70°C/W with standard layout. |

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 |
|---|---|---|---|
| DMT3020LSDQ-7 | Same die, but in U-DFN2020-6 (Type A) package with different pinout (D1/S1/G1/G2/S2/D2) and no thermal pad exposure. | Lacks exposed thermal pad → RθJA = 170°C/W → unsuitable for >0.7W continuous operation. | Select only for legacy board compatibility where thermal pad routing is unavailable. |
| DMN3020LFG-7 | Single-channel variant in same package; identical RDS(ON), Qg, and AEC-Q101 rating but no second channel. | Requires two devices for dual-switch functions → +100% footprint and BOM count vs. DMT3020LFDBQ-13. | Choose when channel isolation must be absolute (no shared source) or when layout constraints prevent dual-channel routing. |
Compared with DMT3020LSDQ-7 and DMN3020LFG-7, the DMT3020LFDBQ-13 uniquely delivers dual-channel functionality with exposed thermal pad in a single AEC-Q101-qualified device - optimizing space, thermal performance, and system-level BOM cost for automotive power switching.

FAQ
Is DMT3020LFDBQ-13 qualified for automotive applications?
Yes. The DMT3020LFDBQ-13 is fully AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and supported by PPAP documentation. It has passed high-temperature gate bias (HTGB), high-temperature reverse bias (HTRB), and human-body model (HBM) ESD tests ≥2kV - meeting Tier-1 automotive supplier requirements.
What is the recommended PCB layout for thermal performance?
Use the manufacturer-recommended 1-inch² copper pad connected to the exposed thermal pad (Pin #1 ID) with ≥4 thermal vias (0.3mm diameter, 0.8mm pitch). Maintain minimum 0.25mm solder mask opening around the pad and avoid solder mask dams between pins to ensure reliable reflow wetting and thermal transfer.
Can DMT3020LFDBQ-13 be used in a half-bridge configuration?
Yes - its independent D1/G1/S1 and D2/G2/S2 terminals support half-bridge topologies. However, S1 and S2 share the same thermal pad and are internally shorted on the package substrate; therefore, it is configured as a common-source dual switch, not a floating high-side/low-side pair. Gate drive isolation must be maintained externally.
Does DMT3020LFDBQ-13 include integrated ESD protection?
No. While the device passes AEC-Q101 ESD qualification (≥2kV HBM), it does not integrate dedicated on-die ESD clamps beyond standard MOSFET gate oxide protection. External TVS diodes are recommended on gate lines in high-noise automotive environments, especially for long harness runs or connector interfaces.
