ESD protection for ultra high-speed interfaces

Rev. 1 — 10 May 2017

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

typical values

Fig 14. Dynamic resistance with negative clamping;

typical values

The device uses an advanced clamping structure showing a negative dynamic resistance.

This snap-back behavior strongly reduces the clamping voltage to the system behind the

ESD protection during an ESD event. Do not connect unlimited DC current sources to the

data lines to avoid keeping the ESD protection device in snap-back state after exceeding

breakdown voltage (due to an ESD pulse for instance).

7. Application information

The device is designed to provide high-level ESD protection for high-speed serial

data buses such as USB3.1, HDMI, DisplayPort, eSATA and LVDS data lines.

When designing the Printed-Circuit Board (PCB), give careful consideration to impedance

matching and signal coupling. Do not connect the signal lines to unlimited current sources

like, for example, a battery.
