Silicon Avalanche Diodes 6000W Transient Voltage Suppression For AC Line Protection RoHS AK6 Series ® The new AK6 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 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) 6KA (see note 1) • Maximum Junction Temp. is 150°C • Storage Temp. -55°C to 175°C • Rated IPP measured with 8 x 20 µsec pulse 6 Mechanical Characteristics SILICON DIODE ARRAYS • Epoxy Encapsulated • Axial lead terminals (solderable per MIL-STD-202 Method 208) • Device code and logo marked on every device Features • RoHS compliant • Foldbak™ technology for superior clamping factor • Glass Passivated Junction for reliabilty • Bi-directional • Ultra compact: 12 times less volume than traditional discrete solutions • Very Low Clamping Voltage • Sharp Breakdown Voltage • Low Slope Resistance Agency Approvals: Recognized under the Components Program of Underwriters Laboratories - UL497B.
