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. They protect sensitive

transmitters and receivers for ultra high-speed signal lines. The device is encapsulated in

a leadless ultra small DFN2111-7 (SOT1358-1) Surface-Mounted Device (SMD) plastic

package.

All signal lines are protected by a special diode configuration offering snapback ultra low

line capacitance of only 0.15 pF. 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 USB 3.1 combination, SD card 3.0 and

Thunderbolt interfaces

 Supports SuperSpeed USB 3.1 at 10 Gbps

 Line capacitance of only 0.15 pF for each channel

 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

 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, tablet computers

 TVs and monitors

 DVD recorders and players

 Notebooks, main board graphic cards and ports

 Set-top boxes and game consoles
