Transient Voltage Suppression Diodes Axial Leaded – 15kA > AK15 series AK15 Series Pb e4 RoHS 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. It features a very fast response and ultra low clamping characteristics over traditional metal oxide ( MOV ) solutions. They can be connected in series and / or parallel to create a very high surge current protection solution.. Agency Approvals Features AGENCY • Very low clamping voltage • Ultra compact: less than one-tenth the size of traditional discrete solutions •Sharp breakdown voltage • Low slope resistance • Bi-directional • Foldbak technology for superior clamping factor • Symmetric in leads width for easier soldering during assembly. • IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact) AGENCY FILE NUMBER E128662 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 15 kA Note: 1.
