SOD 323
The SOD-323 package is a type of surface-mount packaging for semiconductor devices, typically for small signal diodes. The abbreviation "SOD" stands for Small Outline Diode.
The SOD-323 package is characterized by its very small size. It typically measures approximately 2.5 mm long by 1.25 mm wide, though the exact dimensions may vary slightly between different manufacturers.
This package type typically has two leads or terminals, and is designed for surface mount technology, which allows for direct mounting and soldering onto printed circuit boards (PCBs). This makes it well suited for use in high-density mounting designs.
As with any specific component, for detailed information such as pin assignment or electrical characteristics, you should refer to the manufacturer's data-sheet for the specific device in question.
