PUSB3AB4
ESD protection for ultra high-speed interfaces
Rev. 2 — 4 May 2016
Product 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.
1.2 Features and benefits
System-level ESD protection for USB 2.0 and SuperSpeed USB 3.1 up to 10 Gbps,
HDMI, DisplayPort, eSATA and LVDS
Line capacitance of only 0.2 pF maximum for each channel
Outstanding system protection: extremely deep snapback combined with dynamic
resistance of only 0.4
.
All signal lines with integrated rail-to-rail clamping diodes for downstream
ESD protection of
15
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
Design-friendly ‘pass-through’ signal routing
1.3 Applications
The device is designed for high-speed receiver and transmitter port protection:
Smartphones, tablet computers, Mobile Internet Devices (MID) and portable devices
TVs and monitors
DVD recorders and players
Notebooks, main board graphic cards and ports
Set-top boxes and game consoles
