The new AK6 series of high current transient suppressors
have been specially designed for use in A.C. Line Protection
and any demanding applications (AC or DC).They offer supe-
rior clamping characteristics over standard S.A.D. technolo-
gies by virtue of the Littelfuse Foldbak
™
technology, which
provides a clamping voltage which is lower than the ava-
lanche voltage (but above the rated working voltage) there-
fore any voltage rise due to increased current conduction is
contained to a minimum, providing the best possible protec-
tion level. They can also be connected in series and/or
parallel to create very high capacity protection solutions.
