ESD protection for high-speed interfaces

This unidirectional ESD protection device is designed to protect high-speed interfaces such as SuperSpeed USB 3.2 at 10 Gbps, HDMI, DisplayPort, external Serial Advanced Technology Attachment (eSATA), Low Voltage Differential Signaling (LVDS), and Gigabit Multimedia Serial Link (GMSL) Serializer/Deserializer (SerDes) against ElectroStatic Discharge (ESD).

The device is encapsulated in a leadless small DFN2510D-10 (SOT1165D) plastic package with side-wettable flanks (SWF) which allow automatic optical inspection (AOI). The device provides ESD protection up to 15 kV exceeding IEC61000-4-2 level 4 and fulfilling ISO10605.
