Littelfuse SD / SD-C 450W Discrete Unidirectional/Bidirectional TVS Diodes

Littelfuse SD / SD-C 450W Discrete Unidirectional/Bidirectional TVS Diodes

Littelfuse SD Unidirectional and SD-C Bidirectional 450W Discrete TVS Diodes are designed to replace multilayer varistors (MLVs) in electronic equipment for low-speed and DC applications. These 450W TVS diodes are designed to protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. Littelfuse SD / SD-C TVS diodes can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate up to 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
  • AEC-Q101 qualified
Applications
  • Switches / Buttons
  • Test Equipment / Instrumentation
  • Point-of-Sale Terminals
  • Medical Equipment
  • Notebooks / Desktops / Servers
  • Computer Peripherals
  • Automotive Electronics
