Texas Instruments' 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 simplify the board layout.

The ESD122 is offered in two easy routing flow through packages.
