Transient Voltage Suppression Diodes

Speciﬁcations are subject to change without notice.

Revised: 03/04/14

Axial Leaded – 1kA > AK1 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.
