ESD9B5.0ST5G
onsemiESD9B5.0ST5G is an onsemi bidirectional ESD protection diode in a SOD-923 package, protecting one 5 V line in either polarity: maximum clamping voltage 12.5 V, low 15 pF capacitance and IEC 61000-4-2 Level 4 contact protection, in one of the smallest two-terminal footprints in the ESD catalogue — for space-starved portable and wearable interfaces. Two facts govern selection. First, the package: this code is SOD-923 — some channel listings have cited SOD-882 for it, which is a different land pattern, so confirm the footprint against onsemi's datasheet before layout release. Second, bidirectionality: a single device protects lines that swing both ways or where polarity is not fixed, which a unidirectional part cannot do; for a fixed-polarity 5 V rail a unidirectional diode clamps asymmetrically and can be the better fit. The 15 pF capacitance suits control and low-speed data lines rather than RF or multi-gigabit paths. Parameters verified against onsemi documentation.
