Rated IPP measured with 8/20μs pulse. **Functional Diagram** Bi-direcctional ~~ore~~ The AK6-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 Foldback[TM] 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 • IEC-61000-4-2 ESD an Isolated Loop Circuit 15kV(Air), 8kV (Contact) Protector - ESD protection of data - • Both reflow and wave lines in accordance with soldering capable IEC 61000-4-2 - Very low clamping voltage • EFT protection of data • Ultra compact: less lines in accordance with than one-tenth the size IEC 61000-4-4 of traditional discrete • Halogen-free and RoHS solutions compliant - Glass passivated junction - Sharp breakdown voltage - Low slope resistance • Pb-free E4 means 2[nd] level • Bi-directional interconnect is Pb-free and the terminal finish - • Foldback technology for material is silver - superior clamping factor - Symmetric in leads width for easier soldering during assembly. **==> picture [506 x 232] intentionally omitted <==** **----- Start of picture text -----**
