Features
RoHS Compliant
Foldbak
TM
technology for superior clamping factor.

Ultra Compact: 12 times less volume than traditional

Very Low Clamping Voltage
Sharp Breakdown Voltage
Low Slope Resistance
The new AK10 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
TM
technology, which provides a clamping
voltage which is 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.
