ESD protection for ultra high-speed interfaces
5 April 2018
Product data sheet
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.

9. 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.
Note: 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.
Dynamic resistance
The device uses an advanced clamping structure showing a negative dynamic resistance.
This snap-back 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).
