Its 0.5pF capacitance at 1MHz keeps signal integrity intact on high-speed interfaces like USB 2.0, HDMI, or Gigabit Ethernet — a higher-capacitance clamp would round the edges and fail eye-diagram masks. ## Clamping voltage and peak current handling When the line exceeds the 5.4V minimum breakdown voltage, the diode clamps the surge to 9.8V maximum at the rated 1A peak pulse current (8/20µs waveform). That clamping voltage is the ceiling the protected IC sees — stay below its absolute-maximum input rating. ## SOD-923 footprint and temperature range Housed in a SOD-923 surface-mount package, the diode occupies minimal board area — roughly 0.8 mm × 0.6 mm — making it suitable for dense layouts where every square millimetre counts.","metaTitle":"ESD9L5.0ST5G onsemi Zener ESD Protection Diode, SOD-923, 5V","metaDescription":"onsemi ESD9L5.0ST5G Zener ESD protection diode, 5V reverse standoff, 0.5pF capacitance, SOD-923 package.
