AK3-066C-Y

TVS Diodes Datasheet AK3-Y Series Axial Leaded – 3kA RoHS Pb e4 Description The AK3-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 FoldbakTM 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 & Benefits ■ Recognized to UL 497B as an Isolated Loop Circuit Protector Additional Information ■ Both reflow and wave soldering capable ■ Very low clamping voltage Resources Accessories ■ Ultra compact: less than onetenth the size of traditional discrete solutions Samples Agency Recognitions Agency ■ Sharp breakdown voltage ■ FoldbakTM technology for superior clamping factor Maximum Ratings and Thermal Characteristics (TA=25OC unless otherwise noted) Parameter Symbol Value Unit Operating Storage Temperature Range TSTG -55 to 150 °C Operating Junction Temperature Range TJ -55 to 125 ºC Current Rating1 IPP 3 kA ■ EFT protection of data lines in accordance with IEC 610004-4 ■ Halogen-free and RoHS compliant ■ Pb-free E4 means 2nd level interconnect is Pb-free and the terminal finish material is silver ■ Bi-directional E128662 ■ ESD protection of data lines in accordance with IEC 61000-4-2 ■ Glass passivated junction ■ Low slope resistance Agency File Number ■ IEC 61000-4-2 ESD 15kV(Air), 8kV (Contact) ■ Symmetric in leads width for easier soldering during assembly.
