TransientVoltage Suppression Diodes
Axial Leaded – 3kA > AK3 series
Pb e4
RoHS
AK3 Series
Description
The AK3 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..
Features
• Very low clamping voltage • ESD protection of data

• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Ultra compact: less
than one-tenth the size
of traditional discrete
solutions
• Sharp breakdown voltage
• Low slope resistance
