AK20-66C
TRANSIENT VOLTAGE SUPPRESSION DIODES
Description
The AK20 series of high powerTVS diode is specially
designed for meeting severe surge test environment of
both AC and DC line protection applications. It features a
very fast response and ultra low clamping characteristics
over traditional metal oxide ( MOV ) solutions.They can be
connected in series and / or parallel to create a very high
surge current protection solution.
