AK6-Y Series
Description
The AK6-Y series of high powerTVS 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). It
accomplishes this by virtue of the Littelfuse FoldbackTM
technology,which provides a clamping voltage lower
than the avalanche voltage (but above the rated working
voltage); therefore, any voltage rise due to increased
current conduction is maintained at a minimum magnitude,
providing the best possible protection level. These AK
components can be connected in series and / or parallel to
create a very high surge current protection solution.
