LTKAK6 Series
Description
The LTKAK6 series offer superior clamping characteristics
over standard SAD 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.
LTKAK6 in SMTO-218 package provide the enhanced
quality, easy manufacturing and compact mechanical
design than current AKTVS families.
