Compact SMT package saves board space and simplifies manufacturing; suits overvoltage protection, railway, defence, avionics, power grid and industrial transient voltage surge suppressors  

March 2018 – The new LTKAK Series TVS Diodes from Littelfuse is now available in Europe through TTI, Inc., a world leading specialist distributor of electronic components.  Offering superior clamping characteristics compared to standard silicon avalanche diodes, the LTKAK Series features Littelfuse Foldbak technology, which provides a clamping voltage lower than avalanche voltage but above rated working voltage.  Provided in the SMTO-218 package, LTKAK TVS diodes are compact and enable designers to save board space, as well as being easier to manufacture than current AK TVS families. Suitable applications for the Littelfuse LTKAK Series includes cell phone base stations, industrial transient voltage surge suppressors (TVSS), railway trackside signalling and control cabinets, power grid & power distribution systems and defence & avionics applications.

There are two families of devices in the new LTKAK Series TVS diodes, the LTKAK6 and LTKAK10, both offering superior clamping characteristics over standard SAD technologies thanks to Littelfuse Foldbak technology.  This provides a clamping voltage lower than the avalanche voltage (but above the rated working voltage), and therefore, any voltage rise due to increased current conduction is kept to a minimum, providing the best possible protection level.  Surge protection is also excellent at 6kA surge capability for the LTKAK6 and 10kA surge capability for the LTKAK10 (8×20µs waveform). A high power TVS design in a compact and innovative SMT package, the LTKAK6 and LTKAK10 can also be connected in series and/or parallel to create various capability and flexible protection solutions.
