1 SMTO ka > LTKAK6 series LTKAK6 Series RoHS Pb e3 Description The LTKAK6 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 LTKAK6 series can be combined in series or parallel solutions to offer various clamping levels and surge withstand options.

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.
