SP4322 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 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.
