TVS Diodes Axial Leaded 15kA > AK15 series RoHS Pb e4 AK15 Series Descriptios The AK15 series of high power TVS diode is specially designed for meeting severe surge test environment of both AC and DC line protection applications. The AK15 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.. Agency Approvals Features Very low clamping voltage ESD protection of data Agency Agency File Number lines in accordance with Ultra compact: less E128662 IEC 61000-4-2 than one-tenth the size of traditional discrete EFT protection of data solutions lines in accordance with IEC 61000-4-4 Sharp breakdown voltage Maximum Ratings and Thermal Characteristics O Halogen-free (T =25 C unless otherwise noted) Low slope resistance A RoHS compliant Bi-directional Parameter Symbol Value Unit Glass passivated junction Foldbak technology for Operating Storage Temperature superior clamping factor Pb-free E4 means 2nd T -55 to 150 C STG Range level interconnect is Symmetric in leads width Operating Junction Temperature Pb-free and the terminal T -55 to 125 C for easier soldering during J Range finish material is silver assembly. 1 Current Rating I 15 kA PP IEC 61000-4-2 ESD 15kV(Air), 8kV (Contact) Note: 1.
