Vishay Semiconductors VBUS05A1-SD0 BiSy Single Line ESD Protection Diode is an ultra-compact device that clamps positive and negative overvoltage transients to ground. VBUS05A1-SD0 uses an 0603 (metric) chip-level package that is one of the smallest in the industry, requiring three times less board space than packages with a 1006 (metric) size. It is connected between the signal or data line and the ground and offers a high isolation (low leakage current, low capacitance) within the specified working range. Due to the short leads and small package size of the tiny CLP0603 package the line inductance is very low, so that fast transients like and ESD-strike can be clamped with minimal over- or undershoots. VBUS05A1-SD0 features very low capacitance (<0.8pF) and can be used for high speed data ports like HDMI, USB 3.0, or Thunderbold in portable gaming systems, digital cameras, MP3 players, and mobile phones.
