Axial Leaded – 1kA > 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.
