Descriptions
The AK15-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
• No wear-out nor degrade
surge rating over multiple
transient events as long
as within surge capability
• Ultra high power rating
• Very low clamping voltage
• Both reflow and wave
soldering capable
• 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 lead width
for easy soldering during
assembly
• IEC 61000-4-2 ESD 15 kV
(air), 8 kV (contact) rating
• Lightning, 15 kA (8/20 as
defined in IEC 61000-4-5
2nd Edition)
• 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 (IPC/
JEDEC J-STD-609A.01)
