AK10-170C-Y

TVS Diode Datasheet AK10-Y Series Axial Leaded – 10kA RoHS Pb e4 Description The AK10-Y series of high power TVS diode is specially designed for meeting severe surge test environment of both AC and DC line protection applications. It features a very fast response and ultra low clamping characteristics as compared to MOVs (Metal Oxide Varistors). It accomplishes this by virtue of the Littelfuse FoldbackTM 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 maintained at a minimum magnitude, providing the best possible protection level. These AK components can be connected in series and / or parallel to create a very high surge current protection solution. Features ■ Recognized to UL 497B as an Isolated Loop Circuit Protector Agency Approvals Agency Agency File Number ■ Both reflow and wave soldering capable E128662 ■ Very low clamping voltage ■ Ultra compact: less than onetenth the size of traditional discrete solutions Maximum Ratings and Thermal Characteristics (TA=25°C unless otherwise noted) Parameter Symbol Value Unit Operating Storage Temperature Range TSTG -55 to 150 °C ■ Low slope resistance Operating Junction Temperature Range TJ -55 to 125 ºC ■ Bi-directional Current Rating IPP 10 kA ■ Foldback technology for superior clamping factor 1 ■ Sharp breakdown voltage Note: 1. Rated IPP measured with 8/20μs pulse. ■ Symmetric in leads width for easier soldering during assembly. Functional Diagram ■ IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact) ■ ESD protection of data lines in accordance with IEC 61000-4-2 ■ EFT protection of data lines in accordance with IEC 610004-4 ■ Halogen-free and RoHS compliant ■ Glass passivated junction ■ Pb-free E4 means 2nd level interconnect is Pb-free and the terminal finish material is silver Bi-directional Electrical Characteristics (TA=25°C unless otherwise noted) AK10-015C-Y Max.
