ESD protection for ultra high-speed interfaces
Rev. 1 — 25 August 2015
Objective data sheet
1. Product profile
1.1 General description
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.

The device uses an advanced clamping structure showing a negative dynamic resistance.
This snapback behavior strongly reduces the clamping voltage to the system behind the
ESD protection during an ESD event. Do not connect unlimited DC current sources to the
data lines to avoid keeping the ESD protection device in snap-back state after exceeding
breakdown voltage (due to an ESD pulse for instance).
7. Application information
The device is designed to provide high-level ESD protection for high-speed serial
data buses such as HDMI, DisplayPort, eSATA and LVDS data lines.
When designing the PCB, give careful consideration to impedance matching and signal
coupling. Do not connect the signal lines to unlimited current sources like, for example, a
battery.
