Product data sheet
1. Product profile
1.1 General description
The device is designed to protect high-speed interfaces such as SuperSpeed USB,
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 for ultra high-speed
signal lines and 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 0.5 pF. These diodes utilize a unique snap-back structure in order to
provide protection to downstream components from ESD voltages up to
10
kV contact
exceeding IEC 61000-4-2, level 4.
1.2 Features and benefits
System ESD protection for USB 2.0 and SuperSpeed USB 3.1, HDMI 2.0, DisplayPort,
eSATA and LVDS
All signal lines with integrated rail-to-rail clamping diodes for downstream
ESD protection of
10
kV exceeding IEC 61000-4-2, level 4
Matched 0.5 mm trace spacing
Signal lines with
0.05 pF matching capacitance between signal pairs
Line capacitance of only 0.5 pF for each channel
Design-friendly ‘pass-through’ signal routing
1.3 Applications
The device is designed for high-speed receiver and transmitter port protection:
TVs and monitors
DVD recorders and players
Notebooks, main board graphic cards and ports
Set-top boxes and game consoles
