Description
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.
