The new AK10 series of high current transient suppressors have been specifically designed for use in A.C. line protection and any demanding applications (AC or DC). They offer superior clamping characteristics over standard S.A.S technologies by virtue of Littelfuse Foldbak™ technology, which provides a clamping voltage lower than the avalanche voltage. (but above the rated working voltage) These devices can also be connected in series/parallel combinations to create a very high capacity protection solution.
