USB Series
Multilayer Varistors for Universal Serial BUS Protection
DESCRIPTION
USB Series varistors are designed to protect the high speed data lines
against ESD transients. They have very low capacitance and fast turn
on times that makes this series ideal for data and transmission lines with
high data rates. The unique design enables these devices to meet the
rigorous testing criteria of the
IEC 61000-4
standards. New and
improved manufacturing process has created these USB series to be one
of the best plated varistors in the market today.

FEATURES
•Zinc Oxide (ZnO) based ceramic semiconductor devices with non-linear
voltage-current characteristics
• Bi-directional device, similar to back-to-back Zener diodes plus an EMC
capacitor in parallel
• Entire structure made up of conductive ZnO grains surrounded by
electrically insulating barriers, creating varistor like behavior.
• Electrical advantages over Zener diodes are repetitive strike capability,
high in rush current capability, fast turn-on-time and EMI attenuation.
• Protects against ESD to meet
IEC 61000-4-2
15kV (air) and 8kV
(Contact)
•Low Capacitance for high speed datalines
•Available in discrete and array packages (2, 3 and 4 element)
•Low Clamping Voltage
•Low Operating Voltage
•Response time is < 1ns.
