This series will be End of Life (EOL) and is not recommended for new designs. Replacement will be the AK1-Y series.
The AK1 series of high current transient suppressors have been specially designed for use in A.C. line protection and any demanding applications (AC or DC). 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.
