# D_SOD-323

The SOD-323 is a compact surface-mount diode package at just 1.7 x 1.25mm — roughly half the size of the SOD-123. It is the standard package for small signal diodes (BAV99), ESD protection diodes (PESD1CAN), low-capacitance TVS diodes, and small Schottky rectifiers (BAT54) used in high-speed signal paths. The tiny footprint makes it ideal for placing ESD protection close to connector pins and for high-density digital designs where many protection diodes are needed.
