3 Description

The ESD122 is a bidirectional TVS ESD protection

diode array for USB Type-C and HDMI 2.0 circuit

protection. The ESD122 is rated to dissipate contact

ESD strikes at the maximum level specified in the

IEC 61000-4-2 international standard (17-kV Contact,

17-kV Air-gap).

This device features a low IO capacitance per

channel and pin-out to suit symmetric differential

high-speed signal routing making it ideal for

protecting high-speed interfaces up to 10 Gbps such

as USB 3.1 Gen2 and HDMI 2.0. The low dynamic

resistance and low clamping voltage ensure system

level protection against transient events.

Additionally, the ESD122 is an ideal ESD solution for

the USB Type-C Tx/Rx lines. Since the USB Type-C

connector has two layers, using 4-channel ESD

devices require VIAs which degrade the signal

integrity. Using four ESD122 (2-Ch) devices minimize

the number of VIAs and simply the board layout.

The ESD122 is offered in two easy routing flow

through packages.
