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.

2. Features and benefits

• System-level ESD protection for USB 2.0 and SuperSpeed USB 3.1 at 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 Ω

• 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

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
