LTKAK6-076C

TVS Diode Datasheet LTKAK6 Series SMTO-218 - 6KA Pb e3 RoHS Description The LTKAK6 series offers superior clamping characteristics over standard S.A.D. technologies by virtue of the Littelfuse FoldbakTM 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. The LTKAK6 SMT package provides a more compact PCB layout than typical through-hole AK TVS components.
