Pick and Place Friendly TVS Diodes

Featured Product from Littelfuse, Inc.

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 AK TVS families.
