Transient Voltage Suppression Diodes
Axial Leaded – 6kA > AK6 series
AK6 Series
RoHS
Pb e4
Description
The AK6 series of high power TVS 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.

• Very low clamping voltage
• Ultra compact: less
than one-tenth the size
of traditional discrete
solutions
•Sharp breakdown voltage
• Low slope resistance
• Bi-directional
• Foldbak technology for
superior clamping factor
• Symmetric in leads width
for easier soldering
during assembly.
• IEC-61000-4-2 ESD
15kV(Air), 8kV (Contact)
• ESD protection of data
lines in accordance with
IEC 61000-4-2
• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Halogen-free
• RoHS compliant
• Glass passivated junction
• Pb-free E4 means 2nd
level interconnect is
Pb-free and the terminal
finish material is silver
Note:
1. Rated IPP measured with 8/20μS pulse.
