Product details
Overview
DMN3026LVTQ-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in TSOT26 package, featuring 23 mΩ RDS(ON) at VGS = 10 V and 30 mΩ at VGS = 4.5 V, rated for 6.6 A continuous drain current at 25°C, and qualified to AEC-Q101 for automotive power management circuits including DC-DC converters and LED backlighting.
For engineers reviewing the DMN3026LVTQ-7 datasheet, DMN3026LVTQ-7 pinout, DMN3026LVTQ-7 application, or DMN3026LVTQ-7 equivalent, key selection criteria include low RDS(ON) at 4.5 V gate drive, fast switching (tD(on) = 2.2 ns), body diode recovery performance (trr = 6.5 ns), thermal resistance (RθJA = 83 °C/W with 1-in² copper), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This MOSFET employs a trench-gate process optimized for low on-resistance while maintaining controlled gate charge (Qg = 12.5 nC at VGS = 10 V) and low output capacitance (Coss = 65 pF). Its threshold voltage range (1.0–2.0 V) ensures stable turn-on across temperature and supply variation.
The device integrates a robust body diode with VSD = 0.7–1.2 V at 1.0 A and Qrr = 1.7 nC, enabling efficient synchronous rectification and flyback operation. Thermal design is supported by RθJC = 14.5 °C/W and validated junction-to-ambient performance under defined PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum drain-source blocking voltage for 12 V/24 V automotive and industrial DC-DC stages. |
| RDS(ON) | 23 mΩ @ VGS = 10 V - Enables <150 mW conduction loss at 6.6 A, critical for high-efficiency buck regulators. |
| ID (continuous) | 6.6 A @ TA = 25°C - Supports compact power stages without forced airflow in space-constrained modules. |
| Qg | 12.5 nC @ VGS = 10 V - Balances switching speed and gate driver loading for 500 kHz–1 MHz operation. |
| trr | 6.5 ns - Minimizes reverse recovery losses in synchronous rectifier and half-bridge configurations. |
| RθJA | 83 °C/W - Validated with 1-inch² copper pad; enables 1.5 W dissipation at ≤70°C ambient without heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LVTQ-7 | RDS(ON) = 20 mΩ @ 10 V (lower), but ID = 7.0 A - higher conduction capability at cost of slightly higher Qg (13.8 nC). | Better suited for high-current, lower-frequency (<300 kHz) power stages where gate drive strength exceeds 1 A. | Select when prioritizing lowest possible conduction loss over ultra-fast switching; verify gate driver slew rate compatibility. |
| SI2302DS-T1-GE3 | RDS(ON) = 48 mΩ @ 4.5 V (higher), Qg = 4.5 nC (lower), no AEC-Q101 qualification. | Acceptable for consumer-grade 5 V logic-switched loads but unsuitable for automotive or high-reliability industrial use. | Choose only for cost-sensitive non-automotive applications where 4.5 V drive margin is sufficient and qualification is not required. |
Compared with DMN3026LVTQ-7, DMN3025LVTQ-7 delivers lower RDS(ON) at identical VGS, improving efficiency in thermally constrained designs, while SI2302DS-T1-GE3 trades off conduction loss and qualification for reduced gate charge and cost-making it viable only outside automotive and safety-critical systems.

FAQ
What is the maximum continuous drain current for DMN3026LVTQ-7 at 70°C ambient?
The maximum continuous drain current is 5.3 A at TA = +70°C with standard FR-4 PCB layout (2 oz copper, minimum pad). This rating accounts for thermal derating due to increased RθJA at elevated ambient temperatures and ensures safe operation within the SOA limits shown in Figure 12 of the datasheet.
Is DMN3026LVTQ-7 suitable for 3.3 V logic-level gate drive?
No - the device has a gate threshold voltage range of 1.0–2.0 V, but its RDS(ON) is specified only down to VGS = 4.5 V (30 mΩ). At 3.3 V, RDS(ON) rises significantly (≥65 mΩ), increasing conduction loss beyond acceptable levels for most power applications.
Does DMN3026LVTQ-7 include an integrated ESD protection diode?
No - the device does not integrate dedicated ESD protection circuitry. It relies on standard MOSFET gate oxide robustness (±20 V VGSS) and requires external TVS or RC snubbers in high-noise environments such as automotive CAN/LIN bus proximity or motor drive feedback paths.
What is the recommended PCB pad layout for optimal thermal performance?
Use the 1-inch square copper plate layout per Note 7 in the datasheet (RθJA = 83 °C/W). The suggested pad dimensions are provided in AP02001; thermal vias under the drain pads (minimum 6×0.3 mm diameter) connected to inner-layer ground planes further reduce junction temperature by up to 15°C at full load.
