PUSB3TB6数据手册电路保护的TVS-二极管规格书PDF

描述 Description

General description
The device is designed to protect high-speed interfaces such as SuperSpeed and Hi - Speed USB combination, Secure Digital (SD) card 3.0 and Thunderbolt interfaces against ElectroStatic Discharge (ESD).
The device includes six high-level ESD protection diode structures for ultra high-speed signal lines and is encapsulated in a DFN2111-7 (SOT1358-1) leadless ultra small Surface-Mounted Device (SMD) plastic package.
All signal lines are protected by a special diode structure offering ultra low line capacitance of only 0.27 pF. These diodes utilize a unique snap-back structure in order to provide protection to downstream components from ESD voltages up to 10 kV contact exceeding IEC 61000-4-2, level 4.Features and benefits
■ System ESD protection for USB 2.0 and USB 3.0 combination, SD card 3.0 and
   Thunderbolt interfaces
■ All signal lines with integrated rail-to-rail clamping diodes for downstream
   ESD protection of 10 kV exceeding IEC 61000-4-2, level 4
■ Matched 0.5 mm trace spacing
■ Signal lines with  0.05 pF matching capacitance between signal pairs
■ Line capacitance of only 0.27 pF for each channel
■ Design-friendly pass-through signal routing
