The LTKAK6 and LTKAK10 series TVS diodes from Littelfuse offer clamping characteristics superior to those of standard silicon avalanche diode (SAD) technologies. Littelfuse Foldbak technology provides a clamping voltage lower than the avalanche voltage but above the rated working voltage. As a result, any voltage rise due to increased current conduction is minimized. Both series provide the same enhanced quality, easy manufacturing, and compact mechanical design found in AK Series TVS diode families. However, because they are provided in a surface-mount SMTO-218 package, the LTKAK6 and LTKAK10 series allow circuit designers to save even more circuit board space.

The compatible footprint design among LTKAK6 and LTKAK10 series TVS diodes for various breakdown voltages (V_BR) provides the circuit designers design flexibility to leverage the same PCB layout and meet various surge I_PP and V_Z requirements. Typical applications include transient overvoltage protection for cell phone base stations and industrial transient voltage surge suppressors (TVSSs).
