AK1-076C Littelfuse

TVS Diodes Datasheet AK1 Series Axial Leaded 1kA Pb e4 RoHS Description The AK1 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 over traditional metal oxide varistor ( MOV ) solutions. They can be connected in series and / or parallel to create a very high surge current protection solution. Features Very low clamping voltage ESD protection of data lines in accordance with IEC Ultra compact: less than one- 61000-4-2 tenth the size of traditional discrete solutions EFT protection of data lines in accordance with IEC 61000- Sharp breakdown voltage 4-4 Low slope resistance Additional Information Halogen-free Bi-directional RoHS compliant IEC 61 000-4-2 ESD 15kV(Air), Glass passivated junction 8kV (Contact) Pb-free E4 means 2nd level Symmetric in leads width interconnect is Pb-free and for easier soldering during the terminal finish material assembly. is Silver Resources Accessories Samples Agency Approvals Maximum Ratings and Thermal Characteristics Agency Agency File/Certificate Number O (T =25 C unless otherwise noted) A E128662 Parameter Symbol Value Unit Operating Storage Temperature T -55 to 150 C STG Range Operating Junction Temperature T -55 to 125 C Functional Diagram J Range 1 Current Rating I 1 kA PP Note: 1.
