AK1-380C-Y Littelfuse

TVS Diodes Datasheet AK1-Y Series Axial Leaded 1kA RoHS Pb e4 Descriptions The AK1-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). These AK components can be connected in series and / or parallel to create a very high surge current protection solution. Features & Benefits Recognized to UL 497B ESD protection of data lines as an Isolated Loop Circuit in accordance with IEC Protector 61000-4-2 Both reflow and wave EFT protection of data lines in soldering capable accordance with IEC 61000- 4-4 Very low clamping voltage UL Recognized compound Ultra compact: less than one- Agency Recognitions meeting flammability rating tenth the size of traditional V-0 Agency Agency File Number discrete solutions Halogen-free and RoHS Sharp breakdown voltage E128662 compliant Low slope resistance Glass passivated junction Bi-directional Pb-free E4 means 2nd level IEC 61000-4-2 ESD 15kV(Air), interconnect is Pb-free and 8kV (Contact) Maximum Ratings and Thermal Characteristics the terminal finish material O Symmetric in leads width (T =25 C unless otherwise noted) is silver A for easier soldering during Parameter Symbol Value Unit assembly.
