PESD4USB3B-TTS

ESD protection for high-speed interfaces

9. Application information

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

as HDMI, DisplayPort, eSATA and LVDS data lines.

Note: When designing the 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.

Dynamic resistance

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).
