Description

The 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 superior
clamping characteristics over standard S.A.D. technologies
by virtue of the Littelfuse Foldbak technology. Therefore,
any voltage rise due to increased current conduction is
contained to a minimum, providing the best possible
protection level. They can also be connected in series and/
or parallel to create very high capacity protection solutions.
