ESD122 is Dual 0.2pF, ±3.6V, ±18kV ESD Protection Diodes for USB Type-C and HDMI 2.0

The ESD122 is a bidirectional TVS ESD protection diode array for USB Type-C and HDMI 2.0 circuit protection. The ESD122 dissipates contact ESD strikes at the maximum levels specified in the IEC 61000-4-2 international standard (17-kV contact, 17-kV air gap).

The device features low IO capacitance per channel and pin to accommodate AOU3N60 symmetric differential high-speed signal routing, ideal for protecting high-speed interfaces up to 10 Gbps, such as USB 3.1 Gen2 and HDMI 2.0. Low dynamic resistance and low clamping voltage ensure system-level protection from transient events.

Additionally, the ESD122 is an ideal ESD solution for USB Type-C Tx/Rx lines. Since the USB Type-C connector has two layers, VIA is required to use a 4-lane ESD device, which reduces signal integrity. Using four ESD122 (2-channel) devices minimizes the number of VIAs and simplifies board layout.

The ESD122 offers two simple routing flows through the package.
