Transient Voltage Suppression Diodes SMTO-218 - 10KA > LTKAK10 series LTKAK10 Series RoHS Pb e3 Description The LTKAK10 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. LTKAK10 in SMTO-218 package provide the enhanced quality, easy manufacturing and compact mechanical design than current AK TVS families.
