Littelfuse SD05 Uni/Bidirectional TVS Diodes

Littelfuse bidirectional SD05C and unidirectional SD05 TVS Diodes are designed to replace multilayer varistors (MLVs) in electronic equipment for low speed and DC applications. Littelfuse SDO5 and SD05C TVS Diodes will protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. The SD05C can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 30A of 8/20μs induced surge current (IEC61000-4-5) with very low clamping voltages.

Features

  • ESD, IEC61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC61000-4-4, 40A (5/50ns)
  • Lightning, IEC61000-4-5, 30A (tP=8/20μs)
  • Low clamping voltage
  • Low leakage current
  • Small SOD323 package fits 0805 footprints

Applications

  • Switches / buttons
  • Test equipment / instrumentation
  • Point-of-sale terminals
  • Medical equipment
  • Notebooks / desktops / servers
  • Computer peripherals
