12 July 2018

Product data sheet

1. General description

The device is designed to protect high-speed interfaces such as SuperSpeed USB 3.2 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 four high-level ESD protection diode structures. They protect 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 0.29 pF. These diodes utilize a snap-back structure in order to provide protection to

downstream components from ESD voltages up to ±15 kV contact exceeding IEC 61000-4-2,

level 4.
