USB Series Varistor
Multilayer Varistors for Universal Serial BUS Protection
GENERAL 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 make 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 61000-4-2
standards. New and improved manu-
facturing process has created these USB series to be one of the best plat-
ed 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 electri-
cally 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 data lines
• Available in discrete and array packages (2 and 4 element)
• Low Clamping Voltage
• Low Operating Voltage
• Response time is < 1ns
