Product details
Overview
DMT3020LFDBQ-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type B) package, rated for 30V VDSS, 20 mΩ RDS(ON) at VGS = 10 V, and 7.7 A continuous drain current at TA = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive power management and interfacing switches.
For engineers reviewing the DMT3020LFDBQ-7 datasheet, DMT3020LFDBQ-7 pinout, DMT3020LFDBQ-7 application, or DMT3020LFDBQ-7 equivalent, this part supports low-profile, high-reliability automotive switching where tight gate threshold control (1.0–2.5 V), low RDS(ON) at 4.5 V (32 mΩ), and IATF 16949 manufacturing are critical selection criteria.
Technical Context
This dual MOSFET integrates two matched N-channel silicon die in a single 2.0 mm × 2.0 mm U-DFN2020-6 (Type B) package with exposed thermal pad. Its gate threshold voltage range (1.0–2.5 V) enables direct drive from 3.3 V and 5 V logic, while its low RDS(ON) at 4.5 V supports efficient operation in battery-powered and start-stop automotive systems.
The device features integrated body diodes with 1.0 V forward voltage at 2 A, 10 ns reverse recovery time, and 2.6 nC QRR. Thermal resistance is 70 °C/W (with 1-inch² copper pad), enabling 1.8 W steady-state dissipation-critical for space-constrained engine control and ADAS subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Supports 12 V automotive systems with ≥2× supply margin against load dump transients. |
| RDS(ON) @ VGS = 10 V | 20 mΩ - Enables <150 mW conduction loss at 7.7 A, reducing thermal stress in compact layouts. |
| RDS(ON) @ VGS = 4.5 V | 32 mΩ - Ensures robust switching under cold-crank conditions (battery down to 4.5 V). |
| ID (continuous, TA = +25°C) | 7.7 A - Sustains peak currents in motor drivers, LED matrix controls, and solenoid interfaces. |
| Qg @ VGS = 10 V | 7.0 nC - Minimizes gate drive power and enables fast turn-on (<1.8 ns delay) with low-RG drivers. |
| TJ operating range | −55 to +150 °C - Qualified for under-hood and transmission-control environments per AEC-Q101. |
Pinout & Package
Package: U-DFN2020-6 (Type B), 2.0 mm × 2.0 mm × 0.6 mm profile, NiPdAu-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-side or low-side switch node; electrically isolated from D2; connects to load or supply rail. |
| S1 | Source of Channel 1 | Return path for Channel 1; tied to ground or floating reference; shares no internal connection with S2. |
| G1 | Gate of Channel 1 | CMOS-compatible control input; threshold 1.0–2.5 V; requires <100 nA leakage isolation. |
| D2 | Drain of Channel 2 | Independent high-current node; enables dual-load control without cross-conduction risk. |
| S2 | Source of Channel 2 | Independent return path; allows asymmetrical grounding or floating configurations per channel. |
| G2 | Gate of Channel 2 | Separate logic-level input; fully decoupled from G1; supports independent PWM or enable sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| 0.6 mm profile | Enables placement beneath connectors or in stacked PCB assemblies where Z-height is constrained to ≤0.65 mm. |
| AEC-Q101 qualification | Validated for automotive use with HTOL, TC, ESD, and HAST testing-no requalification needed for Tier 1 designs. |
| Low VGS(TH) | 1.0–2.5 V range ensures reliable turn-on with 3.3 V microcontrollers and avoids marginal switching near logic thresholds. |
| Green compound (halogen/antimony-free) | Meets JESD22-A112 and RoHS 3 requirements; Br+Cl <1500 ppm, Sb <1000 ppm-supports end-of-life recycling compliance. |
| Exposed thermal pad | Bottom-side copper pad improves θJA by 100 °C/W vs. non-exposed variants-critical for sustained 1.8 W operation. |
Applications

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 U-DFN2020-6 (Type A) package with different pinout: G1/D1/S1/S2/G2/D2 (vs. D1/S1/G1/D2/S2/G2). | Requires PCB redesign due to swapped source/gate positions; not drop-in compatible. | Select only when legacy board layout uses Type A footprint and thermal performance is secondary. |
| DMN3020LFG-7 | Single-channel variant in same U-DFN2020-6 (Type B); identical RDS(ON), VDSS, and thermal specs. | Requires two devices for dual-load control; increases BOM count and layout area by ~2.5 mm². | Choose when channel independence is unnecessary or when production volume justifies dual sourcing. |
Compared with DMT3020LFDBQ-7, DMT3020LSDQ-7 demands layout revision for pin compatibility, while DMN3020LFG-7 doubles component count and assembly cost-making the dual-channel DMT3020LFDBQ-7 optimal for space- and cost-sensitive automotive modules requiring two independent switches.

FAQ
Is DMT3020LFDBQ-7 suitable for hot-swap applications?
Yes. Its 30 V VDSS, 50 A pulsed drain rating, and 10 ns reverse recovery time support controlled inrush limiting in 12 V hot-swap circuits. The low 1.0–2.5 V gate threshold enables direct interface with hot-swap controllers like the LM5069, and its 70 °C/W θJA (with copper pad) sustains 1.8 W dissipation during transient overload.
What is the maximum allowable gate drive voltage for DMT3020LFDBQ-7?
The absolute maximum gate-source voltage is ±20 V per the datasheet. For reliable long-term operation, gate drive should be limited to 10–12 V to avoid oxide stress acceleration. Driving above 15 V provides negligible RDS(ON) improvement (<1%) but increases gate charge losses and ESD vulnerability.
Does DMT3020LFDBQ-7 require external gate resistors in PWM applications?
Yes. A 6 Ω series gate resistor is recommended (per datasheet test condition) to limit dV/dt-induced shoot-through and control switching speed. Without it, the 1.1 Ω intrinsic gate resistance and 7.0 nC Qg can cause excessive ringing and EMI in 100 kHz+ PWM drives used in LED dimming or motor control.
Can DMT3020LFDBQ-7 replace discrete single-channel MOSFETs in existing designs?
Yes, with layout adaptation. Its dual-channel architecture replaces two discrete SOT-23 or SC-70 MOSFETs, saving >60% board area. However, pinout differs from common dual packages (e.g., SO-8 or TSSOP-8), so routing and thermal pad layout must be updated to match U-DFN2020-6 (Type B) dimensions and terminal assignments.
