This series is not recommended for new designs. Suggests to use  SP1004U-ULC-04UTG/SP3420-04UTG commercial series or SESD1004Q4UG-0020-090 automotive grade series for the new designs in near future. 

The SP3010 integrates 4 channels of ultra-low capacitance rail-to-rail diodes and an additional zener diode to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). This robust device can safely absorb repetitive ESD strikes at the maximum level specified in the IEC61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation. The extremely low loading capacitance also makes it ideal for protecting high speed signal pins such as HDMI, USB3.0, USB2.0, and IEEE 1394.


  • ESD, IEC61000-4-2, ±8kV contact, ±15kV air
  • EFT, IEC61000-4-4, 40A (5/50ns)
  • Lightning, IEC61000-4-5, 3A (tP=8/20μs)
  • Low capacitance of 0.45pF (TYP) per I/O
  • Low leakage current of 0.1 µA (TYP) at 5V
  • Small form factor µDFN package saves board space
