Products within the SP3012 series have been qualified to AEC-Q101 and are appropriate for use in Automotive applications.

The SP3012 integrates 3, 4, or 6 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). These robust devices can safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (±8kV contact discharge) without performance degradation. Their extremely low loading capacitance also makes them ideal for protecting high-speed signal lines such as USB3.0, HDMI, USB2.0, and eSATA.

SP3012 Series devices are available in a choice of compact form factors to give board designers superior layout flexibility:

  • uDFN-6 (SP3012-03UTG)
  • uDFN-10 (SP3012-04UTG)
  • uDFN-14 (SP3012-06UTG)
  • SOT23-6 (SP3012-04HTG)

Products within the SP3012 Series have been qualified to AEC-Q101 and are appropriate for use in automotive applications.
