The LTKAK3 series offers 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. This LTKAK3 series can be combined in series or parallel solutions to offer various clamping levels and surge withstand options. The LTKAK3 SMT package provides a more compact PCB layout than typical through-hole TO-218 AK TVS components. 

Features:

  • Compact design having the Hi Power TVS in surface mount package
  • Patent granted package design
  • Foldbak™ technology for superior clamping factor
  • Tube or tape and reel pack options available
  • Ideal for automatic pick and place assembly and reflow process to reduce the manufacturing cost and increase the soldering quality as compared to axial leaded packages
  • 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-STD609A.01)
  • UL Recognized compound meeting flammability rating V-0
  • Meets MSL level 1, per J-STD-020, lead frame maximum peak of 260°C

Applications:

  • Cell phone base station
  • Industrial TVSS
  • Railway (railroad) trackside signaling and control cabinets
  • Defense & Avionic
  • Power grid & distribution system
