The AK15 series of high current transient suppressors
have been specially designed for use in any demanding
applications (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.
