With a typical capacitance of 6 pF at 1 MHz, this clamp loads high-speed data lines minimally — a practical choice for protecting CAN, LIN, USB 2.0, or LVDS interfaces in engine control units, infotainment, and sensor modules. ## Key ratings that drive the BOM decision The 11 V minimum breakdown voltage gives a 6 V margin above the working rail, which is typical for protecting 5 V logic from ESD transients without nuisance triggering. Capacitance of 6 pF at 1 MHz is low enough that signal edge rates on a 12 Mbps CAN bus or a 480 Mbps USB 2.0 line will not be degraded beyond the transceiver's timing budget. For higher-speed interfaces (e.g., Gigabit Ethernet), a sub-1 pF clamp would be needed; this part fits medium-speed automotive buses. The SOD-923 package (0.85 x 0.60 mm typical body) is one of the smallest ESD footprints available. It suits dense PCB layouts where every square millimetre counts, such as camera modules, key fobs, or BMS cell-monitoring boards.","metaTitle":"ESD9C5.0ST5G onsemi Zener ESD Protection, AEC-Q101, SOD-923","metaDescription":"ESD9C5.0ST5G onsemi Zener ESD suppressor, 5 V reverse standoff, 6 pF capacitance, AEC-Q101 qualified, SOD-923 package.
