Transient Voltage Suppression Diodes Axial Leaded – 10kA > AK10 series AK10 Series RoHS Pb Description The AK10 series of high current transient suppressors have been specially designed for use in A.C. line protection and any 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. They can also be connected in series and/ or parallel to create very high capacity protection solutions.
