说明

Diodes Incorporated 的 DMN2009LSS 是一款 20 V N 沟道增强型功率 MOSFET，采用 8 引脚 SO-8 封装。主要规格包括 20 V 漏极-源极电压、12 A 连续漏极电流、VGS = 10 V 时 8 mΩ 最大 RDS(on)、VGS = 4.5 V 时 9 mΩ、0.5-1.2 V 阈值电压范围、4.5 V 时 16 nC 典型栅极电荷和 2 W 功率耗散。该器件采用沟槽 MOSFET 技术，导通电阻超低。工作温度范围为 -55°C 至 +150°C (TJ)。后缀 LSS 表示 SO-8 封装。.

Diodes Incorporated 的 DMN2009LSS 是一款采用行业标准 SO-8 封装的单 N 沟道增强型功率 MOSFET。它具有 20 V 漏极-源极额定电压和 12 A 连续电流能力，主要针对高电流、低电压电源管理应用，包括直流-直流转换器、负载开关和电机驱动器。.

通过 Diodes 的沟槽 MOSFET 技术，在 VGS = 10 V 时实现了超低的 8 mΩ 最大 RDS(on)（4.5 V 时为 9 mΩ，2.5 V 时为 12 mΩ）。在 10 A 负载下，传导损耗仅为 0.8 W（8 mΩ × 10²A），完全符合 2 W 封装额定值，并有足够的 PCB 铜面积。.

0.5 V 的最小阈值电压确保器件可以由逻辑电平信号驱动，而 1.2 V 的最大阈值则保证了器件在 2.5 V 栅极驱动下的全面增强。如此宽的阈值范围意味着该器件在 2.5 V 和 5 V 栅极驱动下均能正常工作，不过在 4.5 V 及以上电压时，RDS（on）会明显降低。.

SO-8 封装在电流处理和 PCB 面积之间实现了良好的平衡。2 W 的额定功率耗散假定有足够的散热设计 - 通常在漏极引脚上浇注 1 平方英寸的铜，并在内部接地层上设置散热孔。.

DMN2009LSS 属于 Diodes 的 DMN20xx 系列 20 V N 沟道 MOSFET。相关器件包括 DMN2009USS（采用不同 SO-8 变体的相同芯片）和 DMN2016UTS（双 N 沟道版本）。后缀 -13 表示带卷封装。.

对于需要汽车认证的应用，Diodes 提供符合 AEC-Q101 标准的变体（后缀为 ‘Q’）。.

**DMN2009LSS 采用沟槽栅极技术，在硅片上蚀刻垂直沟槽，并在沟槽内形成栅极。这就在单位芯片面积上形成了非常大的沟道宽度，从而实现了超低的 8 mΩ RDS(on)。从源极（顶部）到漏极（底部）的垂直电流流经沟槽结构，实现了高效的电流处理。.

**栅极驱动注意事项：** 0.5-1.2 V 的阈值范围意味着该器件可以从逻辑电平驱动。在 VGS = 4.5 V 时，RDS(on) 最大值为 9 mΩ - 仅略高于 10 V 时。这种逻辑电平优化使该器件适合在负载开关应用中直接驱动 MCU GPIO。在 VGS = 2.5 V 时，RDS(on) 增加到 12 mΩ，对于大多数应用来说仍然很低。.

**SO-8 封装的散热设计：** SO-8 封装主要通过漏极引线（单 MOSFET 配置的引脚 5-8）向 PCB 铜板散热。环境温度为 25°C 时的额定功率为 2 W，漏极焊盘上需要大约 1 平方英寸的 1 盎司铜。要实现更高的散热，连接到内部铜平面的散热孔可以改善散热性能。.

**在同步整流器应用中，该二极管在高压侧和低压侧开关转换之间的死区时间内导通。.
