The SP1233 includes TVS diodes fabricated in a proprietary silicon avalanche technology to protect each I/O pin and 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, IEC61000-4-2) without performance degradation. Additionally, the SP1233 offers up to 20A 8/20 surge rating with low clamping voltages. 

Features:

  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air

  • EFT, IEC 61000-4-4, 40A (5/50ns)

  • Lightning, 20A (8/20 as defined in IEC 61000-4-5 2nd edition)

  • Low clamping voltage

  • Low leakage current

  • AEC-Q101 qualified

  • Moisture Sensitivity Level(MSL -1)

  • Halogen free, lead free and RoHS compliant

Applications:

  • Switches / Buttons

  • Test Equipment / Instrumentation

  • Point-of-Sale Terminals

  • Medical Equipment

  • Notebooks / Desktops / Servers
