PUSB3AB6数据手册电路保护的TVS-二极管规格书PDF

描述 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. They protect sensitive transmitters and receivers for ultra high-speed signal lines. The device is encapsulated in a leadless ultra small DFN2111-7 (SOT1358-1) Surface-Mounted Device (SMD) plastic package.
All signal lines are protected by a special diode configuration offering snapback ultra low line capacitance of only 0.15 pF. These diodes utilize a snapback structure in order to provide protection to downstream components from ESD voltages up to ±15 kV contact exceeding IEC 61000-4-2, level 4.

特性 Features

• System-level ESD protection for USB 2.0 and USB 3.1 combination, SD card 3.0 and Thunderbolt interfaces
• Supports SuperSpeed USB 3.1 at 10 Gbps
• Line capacitance of only 0.15 pF for each channel
• All signal lines with integrated rail-to-rail clamping diodes for downstream ESD protection of ±15 kV exceeding IEC 61000-4-2, level 4
• Matched 0.5 mm trace spacing
• Design-friendly pass-through signal routing
