SP3420 Series - 0.32pF, 6A Diode Array

Roll Over to Zoom

The SP3420 includes four channel ultra low capacitance and high-level ESD protection diodes to protect high-speed data rate such as USB 3.1, DisplayPort, Thunderbolt, and e-SATA. The typical capacitance of 0.32pF helps ensure signal integrity and this robust device can safely absorb repetitive ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation safely dissipate 6A of 8/20μs surge current (IEC 61000-4-5 2nd edition).


  • ESD, IEC 61000-4-2, ±12kV contact, ±15kV air
