Zener diodes fabricated in a proprietary silicon avalanche technology protect each I/O pin to provide a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD). These robust diodes can safely absorb repetitive ESD strikes at ±30kV(contact discharge, IEC 61000-4-2) without performance degradation. Additionally, each diode can safely dissipate 7A of 8/20µs surge current (IEC61000-4-5) with very low clamping voltages.


  • ESD, IEC61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC61000-4-4, 40A (5/50ns)
  • Lightning, IEC61000-4-5, 7A (8/20µs)
  • Low leakage current of 100nA (MAX) at 5V
  • Tiny SOD723/ SOD882 package saves board space
  • Fits solder footprint of industry standard 0402 (1005) devices


  • Mobile phones
  • Smart phones
  • PDAs
  • Portable navigation devices
  • Digital cameras
  • Portable medical devices
