Description
The AK6-Y 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
as compared to MOVs (Metal Oxide Varistors). It
accomplishes this by virtue of the Littelfuse FoldbackTM
technology,which provides a clamping voltage lower
than the avalanche voltage (but above the rated working
voltage); therefore, any voltage rise due to increased
current conduction is maintained at a minimum magnitude,
providing the best possible protection level. These AK
components can be connected in series and / or parallel to
create a very high surge current protection solution.
Features
• Recognized to UL 497B as
an Isolated Loop Circuit
Protector
• Both reflow and wave
soldering capable
• Very low clamping voltage
• Ultra compact: less
than one-tenth the size
of traditional discrete
solutions
•Sharp breakdown voltage
• Low slope resistance
• Bi-directional
• Foldback 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 and RoHS
compliant
• Glass passivated junction
• Pb-free E4 means 2nd level
interconnect is Pb-free
and the terminal finish
material is silver
