The AK3-Y series of high power TVS diode is specially designed for meeting severe surge test environment of both AC and DC line protection applications. It features a very fast response and ultra low clamping characteristics as compared to MOVs (Metal Oxide Varistors). It accomplishes this by virtue of the Littelfuse FoldbakTM technology,which provides a clamping voltage lower than the avalanche voltage (but above the rated working voltage); therefore, any voltage rise due to increased current conduction is maintained at a minimum magnitude, providing the best possible protection level. These AK components can be connected in series and / or parallel to create a very high surge current protection solution.

Features & Benefits:

  • Recognized to UL 497B as an Isolated Loop Circuit Protector
  • Both reflow and wave soldering capable
  • Very low clamping voltage
  • Ultra compact: less than one tenth the size of traditional discrete solutions
  • Sharp breakdown voltage
  • Low slope resistance
  • Bi-directional
  • FoldbakTM technology for superior clamping factor
  • Symmetric in leads width for easier soldering during assembly.
  • IEC 61000-4-2 ESD 15kV(Air), 8kV (Contact)
  • ESD protection of data lines in accordance with IEC 61000-4-2
  • EFT protection of data lines in accordance with IEC 61000-4-4
  • Halogen-free and RoHS compliant
  • Glass passivated junction
  • Pb-free E4 means 2nd level interconnect is Pb-free and the terminal finish material is silver
