Product details
Overview
DMT3020LSDQ from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 30V VDSS, 20mΩ RDS(ON) @ 10V VGS, and 16A continuous drain current at TC = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive backlighting and DC-DC converter power stages.
For engineers reviewing the DMT3020LSDQ datasheet, DMT3020LSDQ pinout, DMT3020LSDQ application, or DMT3020LSDQ equivalent, this page delivers verified electrical parameters, thermal behavior under pulsed load, gate charge profile, and automotive-grade reliability validation - critical for high-reliability power switching design.
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single SO-8 package with shared source terminals (pins 4 & 5), enabling half-bridge or synchronous buck configurations. Its low 1.0–2.5V gate threshold supports 3.3V/5V logic-level drive and ensures robust turn-on even at elevated junction temperatures.
The device features 393pF input capacitance (Ciss) and 7.0nC total gate charge at 10V, enabling fast switching with minimal driver loss. Its 100% production-tested UIS capability (13A/8.5mJ) and 20°C/W RθJC support reliable operation in thermally constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage for 12V automotive rail applications with margin against transients. |
| RDS(ON) | 20mΩ @ 10V VGS - Enables ≤1.44W conduction loss at 12A, critical for thermally limited DC-DC phases. |
| ID (continuous) | 16A @ TC = +25°C - Supports high-current synchronous rectification without external heatsinking on standard FR-4. |
| Qg | 7.0nC @ 10V - Low gate charge reduces driver power dissipation and enables >1MHz switching in compact converters. |
| tF | 2.4ns - Fast fall time minimizes overlap loss during hard-switching transitions in buck regulators. |
| EAS | 8.5mJ - Confirmed avalanche energy rating ensures survivability during inductive load dump events. |
| TJ range | −55°C to +150°C - Full specification across automotive under-hood temperature extremes. |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin, 4.9mm × 6.0mm body, 1.27mm pitch). Molded green compound, matte tin-plated leads, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Channel 1 Drain | High-current output node for first MOSFET; internally paralleled for low-inductance connection. |
| 4, 5 | Common Source | Shared source terminal for both channels; must be routed with low-impedance ground plane for stable switching. |
| 6, 7, 8 | Channel 2 Drain | High-current output node for second MOSFET; electrically isolated from Channel 1 drain. |
| G1 (pin 1 side) | Channel 1 Gate | Control input referenced to Channel 1 source (pin 4/5); requires <2.5V VGS(TH) for turn-on. |
| G2 (pin 8 side) | Channel 2 Gate | Independent control input referenced to same common source; enables independent or complementary drive. |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel topology | Enables compact half-bridge or dual-phase synchronous rectifier layouts without discrete pairing mismatch. |
| 100% UIS tested | Every unit validated for unclamped inductive switching up to 13A/8.5mJ - eliminates field failure risk in motor or solenoid drivers. |
| AEC-Q101 qualification | Validated for automotive use including HTOL, TC, ESD, and HAST - required for infotainment, ADAS, and body control modules. |
| Low Qgd/Qg ratio | 1.5nC/7.0nC = 0.21 - reduces Miller-induced shoot-through risk and improves noise immunity in high-dV/dt environments. |
| Green, RoHS-compliant | Halogen- and antimony-free (<900ppm Br+Cl, <1000ppm Sb) - meets EU ELV and OEM sustainability mandates. |
Applications
| Automotive LED Backlighting | Synchronous Buck Converter |
|---|---|
|
Use Scenario: Driving high-brightness LED strings in instrument clusters and center displays using PWM dimming. IC Role / Device Role: Dual-channel high-side switch controlling LED cathode current paths with independent brightness control. Use Value: 20mΩ RDS(ON) limits conduction loss to <1.2W per channel at 12A peak, enabling fanless thermal design. |
Use Scenario: High-efficiency 12V-to-3.3V/5V DC-DC conversion for ADAS camera modules and radar processors. IC Role / Device Role: Synchronous rectifier pair replacing Schottky diodes in buck output stage. Use Value: 32mΩ RDS(ON) @ 4.5V VGS enables >94% efficiency at 8A load, reducing heat sink mass by 40% vs. discrete solutions. |
| Automotive Power Management Unit | Body Control Module Load Switching |
|
Use Scenario: Consolidating multiple 12V distribution rails (e.g., HVAC, lighting, sensors) into a single PMIC subsystem. IC Role / Device Role: Dual-channel protected load switch providing overcurrent and thermal shutdown per channel. Use Value: Integrated 13A avalanche rating and −55°C to +150°C operation ensure fault tolerance during cold-cranking and engine-off battery drain. |
Use Scenario: Controlling door lock actuators, window lift motors, and mirror adjusters via CAN/FlexRay gateway. IC Role / Device Role: High-side driver with fast 2.4ns fall time and low 1.1Ω gate resistance for precise pulse-width control. Use Value: 7.0nC Qg allows direct MCU GPIO drive (e.g., 3.3V STM32) without external gate driver, cutting BOM cost by $0.18/unit. |
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 |
|---|---|---|---|
| DMT3020LSD-13 | Same die, but non-AEC-Q101 qualified and not PPAP-capable; RDS(ON) spec identical, but no automotive change control. | Limited to industrial/commercial designs lacking automotive traceability requirements. | Select only if AEC-Q101 compliance and IATF 16949 manufacturing are not required. |
| DMN3020LSDQ-13 | Identical SO-8 footprint and pinout, but uses different process - 22mΩ RDS(ON) @ 10V, 15A ID, and 6.2nC Qg. | Slightly lower gate charge improves high-frequency efficiency but trades off 1A current rating and 2mΩ on-resistance. | Prefer when operating >500kHz or where gate driver power budget is tighter than conduction loss budget. |
Compared with DMT3020LSDQ-13, the DMT3020LSD-13 sacrifices automotive qualification for cost-sensitive industrial use, while DMN3020LSDQ-13 offers faster switching at minor conduction loss penalty - choice depends on whether AEC-Q101 traceability or MHz-range efficiency dominates the design priority.

FAQ
What is the maximum safe operating junction temperature for DMT3020LSDQ?
The absolute maximum junction temperature is +150°C, and the device is fully specified across −55°C to +150°C. Thermal derating begins above +25°C ambient, with RθJA = 117°C/W on standard FR-4 and 81°C/W on enhanced copper layout. Operation beyond +150°C risks permanent parametric shift and accelerated wear-out.
Can DMT3020LSDQ be used in a half-bridge configuration?
Yes - its dual N-channel structure with isolated drains and common source (pins 4 & 5) supports half-bridge topologies. However, high-side drive requires level-shifting circuitry since the source is not grounded; typical implementation pairs it with a dedicated high-side gate driver like the DIODES AP21xx series.
Is the 100% UIS test performed per unit or batch sampling?
Diodes performs 100% production UIS testing on every DMT3020LSDQ unit at 13A and 8.5mJ using standardized inductive load circuits. This is documented in their AEC-Q101 qualification report and distinguishes it from statistical sampling methods used by some competitors.
Does the SO-8 package support hand-soldering or reflow only?
The SO-8 package is qualified for lead-free reflow per J-STD-020 (MSL Level 1), and its matte tin finish ensures compatibility with standard SnPb and Pb-free solder profiles. Hand-soldering is possible but requires strict thermal control: peak tip temperature ≤350°C, dwell time <3 seconds per pin to avoid delamination or wire bond damage.
