PUSB3FR6

PUSB3FR6 ESD protection for ultra high-speed interfaces 11 October 2018 Product data sheet 1. General description The device is designed to protect high-speed interfaces such as SuperSpeed and Hi-Speed USB combination, SD-memory 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. 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 structure offering ultra low line capacitance of only 0.35 pF. These diodes utilize a snap-back structure in order to provide protection to downstream components from ESD voltages up to ±15 kV contact exceeding IEC 61000-4-2, level 4. 2. Features and benefits System-level ESD protection for USB 2.0 and USB 3.2 combination, SD-memory card and thunderbolt interfaces Supports SuperSpeed USB 3.2 at 10 Gbps 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 Line capacitance of only 0.35 pF for each channel Design-friendly ‘pass-through’ signal routing 3. Applications The device is designed for high-speed receiver and transmitter port protection: Portable and wearable devices Smartphones and tablet PCs TVs and monitors DVD recorders and players Notebooks, main board graphic cards...
