ESD122 ESD Protection Diode

Texas Instruments ESD122 ESD Protection Diode 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 (17kV Contact, 17kV Air-gap). This device features a low IO capacitance per channel and pin-out to suit symmetric differential high-speed signal routing. This feature makes the device ideal for protecting high-speed interfaces up to 10Gbps, such as USB 3.1 Gen2 and HDMI 2.0. The low dynamic resistance and clamping voltage ensure system-level protection against transient events. The Texas Instruments ESD122 is also an ideal ESD solution for the USB Type-C Tx/Rx lines. Since the USB Type-C connector has two layers, using a 4-channel ESD device requires VIAs, which degrade the signal integrity. Four ESD122 (2-Ch) devices minimize the number of VIAs and simplify the board layout.
