www.DataSheet.co.kr Transient Voltage Suppression Diodes Axial Leaded – 3kA > AK3 series AK3 Series Description RoHS Pb The AK3 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. Agency Approvals AGENCY AGENCY FILE NUMBER E128662 Features • Halogen-Free • RoHS compliant •  Foldbak technology for superior clamping factor •  Glass passivated junction • Bi-directional Unit °C ºC kA Maximum Ratings and Thermal Characteristics (TA=25OC unless otherwise noted) Parameter Operating Storage Temperature Range Operating Junction Temperature Range Current Rating1 Note: 1.
