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 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 data lines • Available in discrete and array packages (2 and 4 element) • Low Clamping Voltage • Low Operating Voltage • Response time is < 1ns PINOUT CONFIGURATION USB0001/0005/0006 0603 and 0402 (Single) MECHANICAL CHARACTERISTICS • Available in EIA 0603 (Single), 0405 (Dual) and 0612 (Quad) cases • Plated Tin over Nickel Barrier • Packaged in Tape & Reel USB0002 0405 (Dual) PART NUMBERING USB 0001 D P Style Case Size 0001 = 0603 (Single) 0002 = 0405 (2-Element) 0004 = 0612 (4-Element) 0005 = 0402 (Single) 0006 = 0402 (Single) Packaging Code (Reel Size) D = 7" (1,000 pcs.)
