Silicon Avalanche Diodes RoHS AK10 Series (R) The new 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 FoldbakTM technology, which provides a clamping voltage which is 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. Maximum Ratings * Current Rating (IPP) 10KA (see note 1) * Maximum Junction Temp. is 150C * Storage Temp. -55C to 175C * Rated IPP measured with 8 x 20 sec pulse 6 SILICON DIODE ARRAYS Max .
