AK1-076C-Y

TVS Diodes Axial Leaded – 1kA > AK1-Y series AK1-Y Series RoHS Pb e4 Descriptions The AK1-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). These AK components can be connected in series and / or parallel to create a very high surge current protection solution.
