The AK20-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 FoldbackTM 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:

  • No wear-out nor degrade surge rating over multiple transient events as long as within surge capability
  • Ultra high power rating
  • Very low clamping voltage
  • Reflow soldering capability
  • Ultra compact: less than one-tenth the size of traditional discrete solutions
  • Sharp breakdown voltage
  • Low slope resistance
  • Bi-directional
  • Foldbak technology for superior clamping factor
  • Symmetric lead width for easy soldering during assembly
  • IIEC 61000-4-2 ESD 15 kV (air), 8 kV (contact) rating
  • Lightning, 20 kA (8/20 as defined in IEC 61000-4-5 2nd edition)
  • EFT protection of data lines in accordance with IEC 61000-4-4
  • UL Recognized compound meeting flammability rating V-0
  • 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 (IPC/ JEDEC J-STD-609A.01)
