Housed in surface mount SMTO-218 package for automatic pick and place assembly and reflow processes, LTKAK6 and LTKAK10 Series feature Littelfuse Foldbak technology, which provides clamping voltage lower than avalanche voltage but above rated working voltage, minimizing voltage rise due to increased current conduction. Typical applications include transient overvoltage protection for cell phone base stations, railway trackside signaling/control cabinets, power grid and distribution systems.
