ESD protection for ultra high-speed interfaces

The device is designed to protect high-speed interfaces such as SuperSpeed USB 3.1 at 10 Gbps, High-Definition Multimedia Interface (HDMI), DisplayPort, external Serial Advanced Technology Attachment (eSATA) and Low Voltage Differential Signaling (LVDS) interfaces against ElectroStatic Discharge (ESD).

The device includes a high-level ESD protection diode structure protecting sensitive transmitters and receivers for ultra high-speed signal lines. The device is encapsulated in a leadless small DFN2510A-10 (SOT1176-1) plastic package.

All signal lines are protected by a special diode configuration offering ultra low line capacitance of only 0.2 pF maximum. These diodes utilize a snapback structure in order to provide protection to downstream components from ESD voltages up to ±15 kV contact exceeding IEC 61000-4-2, level 4.
