USB Series Varistor
Low Capacitance Multilayer Varistors
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.
GENERAL CHARACTERISTICS
• Operating Temperature: -55ºC to 125ºC
• Working Voltage: ≤ 18Vdc
• Case Size: 0402, 0603, 0405 2x array, 0612 4x array
• Typical Capaciatane: 3pF, 6pF, 10pF
PINOUT CONFIGURATION
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 elec-
trically 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
