Description:

The ESD122 is a bidirectional TVS ESD protection diode array designed for USB Type-C and HDMI 2.0 circuit protection. The ESD122 is rated to dissipate contact ESD strikes at the maximum level specified by the IEC 61000-4-2 international standard (17kV contact discharge, 17kV air-gap discharge). The device features low I/O capacitance per channel and per pin to accommodate symmetric differential high-speed signal routing, making it an ideal choice for protecting high-speed interfaces up to 10Gbps, such as USB 3.1 Gen 2 and HDMI 2.0. Low dynamic resistance and low clamping voltage ensure system-level protection against transient events. Furthermore, the ESD122 is an ideal ESD solution for USB Type-C Tx/Rx lines. Since the USB Type-C connector has two layers, using a 4-channel ESD device requires VIAs that degrade signal integrity. Using four ESD122 (2-channel) devices minimizes the number of VIAs and simplifies board layout. The ESD122 is offered in two easy, flow-through routing packages.
