Description
The AK3 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, 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
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.
Features
• Very low clamping
•Ultra compact: less
• Sharp breakdown voltage
• Low slope resistance
