PUSB3FR4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 USB 3.2 at 10 Gbps, High-Definition Multimedia Interface (HDMI), DisplayPort, external Serial Advanced Technology Attachment (eSATA) and Low Voltage Differential Signaling (LVDS) interfaces against ElectroStatic Discharge (ESD).
The device includes four 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 small DFN2510A-10 (SOT1176-1) plastic package.
All signal lines are protected by a special diode configuration offering ultra low line capacitance of only 0.29 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, level4.

特性 Features
