PESDxUSB3S series

ESD protection for differential data lines

7.

Application information

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

data line pairs such as:

When designing the PCB, give careful consideration to impedance matching and signal

coupling. Do not connect the protected signal lines to unlimited current sources like, for

example, a battery.

Since the SuperSpeed TX/RX lines are separated by GND or VBUS from the Hi-Speed

lines, PESD1USB3S makes it easy to achieve same signal lengths, straight routing, and

optimal positioning for ESD protection directly at the connector.
