SP4322-01ETG is specifically designed to protect high-speed interfaces against ElectroStatic Discharge (ESD), such as DisplayPort interfaces and USB 3.1 Gen 1. The signal line is protected by low line  capacitance of 0.4 pF typical.

SP4322-01ETG can absorb repetitive ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard without performance degradation and safely dissipate 11A of 8/20μs surge current (IEC 61000-4-5 2nd edition).

Excellent low capacitance, clamping capability, low leakage, and fast response time make this part an ideal solution for protecting high speed data lines.
