SP3401 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 a TVS diode offering low line capacitance of 0.35 pF typical. SP3401 can safely absorb repetitive ESD strikes up to ±18 kV contact exceeding IEC 61000-4-2, level 4 ( ±8kV contact discharge).
Excellent low capacitance, clamping capability, low leakage, and fast response time make this parts an ideal solution for protecting high speed data lines.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the component. This is a stress only rating and operation of the component at these or any other conditions above those indicated in the operational sections of this specification is not implied.
