SP3401 Series - 0.35pF, 18kV Diode Array

Roll Over to Zoom

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.


  • ESD, IEC 61000-4-2, ±18kV contact, ±30kV air 
  • EFT, IEC 61000-4-4, 80A (tP=5/50ns) 
  • Lightning, IEC 61000- 4-5 2nd edition, 10A (tP=8/20μs) 
  • Low capacitance of 0.35pF (TYP) per I/O
