AGENCY AGENCY FILE NUMBER E128662 Agency Approvals RoHS Pb e3 The LTKAK10 series 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 various capability and flexible protection solutions. LTKAK10 in SMTO-218 package provide the enhanced quality, easy manufacturing and compact mechanical design than current AK TVS families. Note: Using 8/20μs wave shaped defined in IEC 61000-4-5. Functional Diagram Bi-direcctional

  • High Power TVS designed in a surface mount and compact SMTO-218 package
  • Patent pending package design
  • Foldbak technology for superior clamping factor
  • Option for pack in tube or tape and reel.
  • Ideal for automatic pick and place assembly and reflow process to reduce the manufacturing cost and increase the soldering quality compared to axial leads package
  • Bi-directional
  • Low clamping and slope resistance.
  • Sharp breakdown voltage.
  • Meet MSL level1, per J-STD-020, LF maximun peak of 260°C
  • Halogen free and RoHS compliant
  • Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD- 609A.01)
  • UL Recognized epoxy meeting flammability rating V-0
