ESD protection for ultra high-speed interfaces

The device is designed to protect high-speed interfaces such as SuperSpeed and Hi - Speed USB combination, Secure Digital (SD) card 3.0 and Thunderbolt interfaces against ElectroStatic Discharge (ESD).

The device includes six high-level ESD protection diode structures for ultra high-speed signal lines and is encapsulated in a DFN2111-7 (SOT1358-1) leadless ultra small Surface-Mounted Device (SMD) plastic package.

All signal lines are protected by a special diode structure offering ultra low line capacitance of only 0.27 pF. These diodes utilize a unique snap-back structure in order to provide protection to downstream components from ESD voltages up to ±10 kV contact exceeding IEC 61000-4-2, level 4.
