Littelfuse SD Series 450W Discrete Unidirectional TVS Diodes are designed to protect against destructive electrostatic discharges (ESD) and lightning-induced surge currents. These fast-acting TVS Diodes are ideal for replacing 0805 size multilayer varistors (MLVs) in low speed and DC applications because they can safely absorb repetitive ESD strikes at ±30kV without performance degradation and safely dissipate up to 30A of surge current. Their low dynamic resistance provides up to a 50 percent reduction in clamping voltage compared to competing technologies.

  • ESD: IEC61000-4-2, ±30kV contact discharge
  • Lightning: IEC61000-4-5, 30A (tP=8/20μs)
  • Low dynamic resistance
  • No inherent wear-out factor
  • SOD-323 package fits inside existing 0805 PCB footprints
  • AEC-Q101 qualified


Protecting buttons, switches, power ports, and other various low-speed I/Os in:

  • Automotive electronics
  • Test equipment
  • Point-of-sales terminals
  • Notebook computers
  • Servers
  • Medical equipment
