ESD protection for ultra high-speed interfaces
Rev. 1 — 19 August 2014
Product data sheet
1. Product profile
1.1 General description
The device is designed to protect high-speed interfaces such as SuperSpeed and
Hi - Speed USB combination, Secure Digital (SD) card 3.0 and Thunderbolt interfaces
against ElectroStatic Discharge (ESD).
The device includes six high-level ESD protection diode structures for ultra high-speed
signal lines and is encapsulated in a DFN2111-7 (SOT1358-1) leadless ultra small
Surface-Mounted Device (SMD) plastic package.
All signal lines are protected by a special diode structure offering ultra low line
capacitance of only 0.27 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 USB 3.0 combination, SD card 3.0 and
Thunderbolt interfaces
 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 0.27 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:
 Portable and wearable devices
 Smartphones and tablet PCs
 TVs and monitors
 DVD recorders and players
 Notebooks, main board graphic cards and ports
 Set-top boxes and game consoles
