USB 3.0 electrostatic protection
Circuit Protection of USB 3.0 solution
As shown at the left, there are two options for protection. In the upper schematic, an SP3010 is used on the Super Speed lines, and an SP3003-02XTG is used on the High Speed lines. For an integrated approach, the SP3011-06UTG is used to protect all of the data lines (as shown below).
In addition to the recommendations above, the Ruilon portfolio offers other solutions. For example: If the operating current of the power bus is higher or lower, a PTC with a suitable rating can be selected.
IEC 61000-4-2 is the standard specification most suitable for this interface. This test proves that the end product is not vulnerable to ESD.
