Application Information

To design USB3.0 link for best system level ESD performance and error free Signal Integrity is mandatory.

To bring both requirements together, the ESD protection devices has to provide excellent ESD and a very low

device capacitance. The Infineon ESD3V3U4ULC in “array” configuration, combined with a clear and straight

forward “full through” layout fulfills these requirements in the best way.
