The SP3145 represents an industry first: unidirectional ESD protection in a 01005 type package. Unidirectional protection should be favored over bi directional performance, particularly on logic and data lines, which typically do not transit zero volts during standard operation. Fast-acting, semiconductor based technology can withstand multiple ESD events, without wear-out or degradation. Low nominal capacitance makes this product meaningful for interfaces running at high data rates, approaching 5 GHz clock speeds.


  • Industry-first unidirectional protection, critical for data line protection, and any interface which does not transit zero volts
  • ESD, IEC 61000-4-2, ±20kV contact, ±25kV air
  • EFT, IEC 61000-4-4, 40A (5/50ns)
  • Lightning, IEC 61000-4-5,2nd edition, 1A (tp=8/20μs)
  • Low capacitance of 0.35pF (@ VR=0V)
  • Low leakage current of 20nA (max) at 2.8V
  • Industry’s smallest single channel form factor, nominally 01005
  • Halogen free, Lead free and RoHS compliant
