Littelfuse AK6-FB Axial Leaded TVS Diodes

Littelfuse AK6-FB Axial Leaded TVS Diodes are designed to meet the severe surge-test environment for both AC and DC line-protection applications. These diodes feature a very fast response and ultra-low clamping characteristics as compared to Metal Oxide Varistors (MOVs). The AK6-FB TVS diodes offer a 6kA current rating and are capable of both reflow and wave soldering. These diodes maintain any voltage rise due to increased current conduction at a minimum magnitude, providing the best possible protection level. The AK6-FB TVS diodes provide a clamping voltage lower than the avalanche voltage (but above the rated working voltage). These diodes are halogen-free and RoHS compliant.

Features

  • Controlled Foldback technology for superior clamping performance
  • Both reflow and wave soldering capable
  • Typical failure mode is a short from over-specified voltage or current
  • Low dynamic resistance
  • Symmetric in lead width for easier soldering during assembly
  • IEC 61000-4-2 ESD 15kV(air) and 8kV (contact)
  • EFT protection of data lines in accordance with IEC 61000-4-4
  • VBR at TJ = VBR at 25°C x (1+αT x (TJ - 25))(αT:temperature coefficient, typical value is 0.1%)
  • Glass-passivated junction
  • Pb-free E4 means the 2nd level interconnect is Pb-free and the terminal finish material is silver
  • Halogen-free
  • RoHS compliant
