The AK3 series of high current transient suppressors have been specially designed for use in A.C. line protection and any demanding applications (AC or DC). They offer superior clamping characteristics over standard S.A.D. technologies by virtue of the Littelfuse Foldbak™ 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 contained to a minimum, providing the best possible protection level. They can also be connected in series and/or parallel to create very high capacity protection solutions.

Features:

  • Halogen-Free
  • RoHS compliant
  • Foldbak™ technology for superior clamping factor
  • Glass passivated junction
  • Bi-directional
  • Ultra compact: over 10 times less volume than traditional discrete solutions
  • Very low clamping voltage
  • Sharp breakdown voltage
  • Low slope resistance
