Functional Diagram
Description
The AK3 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..
Features
• 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)
• E SD protection of data
lines in accordance with
IEC 61000-4-2
• E FT 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
