The SP4050 integrates low capacitance diodes with an additional zener diode to protect each I/O pin against ESD and high surge events. This robust component can safely absorb up to 20A per IEC 61000-4-5 2nd edition(tp=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC 61000-4-2 International Standard. Their low loading capacitance also makes them ideal for protecting high speed signal pins.

Features:

  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC 61000-4-4, 40A (5/50ns)
  • Lightning, IEC 61000-4-5 2nd edition,20A (tp=8/20μs)
  • Low capacitance of 4.4pF (TYP) per I/O
  • Low leakage current of 0.5μA (MAX) at 2.5V
  • Moisture Sensitivity Level (MSL-1)
  • Halogen free, Lead free and RoHS compliant

Applications:

  • LCD/PDP TVs
  • Desktops
  • Game Consoles
  • Set Top Boxes
  • Notebooks
