Littelfuse AK3 Series Transient Voltage Suppression (TVS) Diodes have been specially designed for use in A.C. line protection and any particularly demanding applications (AC or DC). They offer superior clamping characteristics over standard S.A.D. 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. Littelfuse AK3 Series TVS Diodes can also be connected in series and/or parallel to create very high capacity protection solutions.
