Improved ESD protection for high-speed serial data links

February 21, 2014 // By Julien Happich
Infineon Technologies’ ESD105 series of Transient Voltage Suppression (TVS) devices protect high speed interfaces of electronic systems from Electrostatic Discharge (ESD) strikes.

Designed with miniaturised integrated packages for mobile devices, the ESD105 series addresses TVS for high-speed data interfaces, such as USB 3.0, Gbit Ethernet, Firewire and HDMI links.

With very-low clamping voltage (10V at 8 kV) and ultra-low capacitance (C = 0.3 pF) the ESD105 TVS diodes (single line) enable you to achieve strict requirements for ESD robustness and signal quality of the high-speed interfaces used in the latest generation smartphones and tablet computers. The new series provides protection that exceeds the specifications of IEC61000-4-2 in 2-pin packages (0201, 0402). The leakage current is under 20 nA, contributing to longer system battery life. A dedicated pad-layout keeps PCB layout simple and minimise parasitic effects.
