PUSB3AB4 ESD protection for ultra high-speed interfaces 10 October 2019 Product data sheet 1. General 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 a high-level ESD protection diode structure protecting 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 0.2 pF maximum. 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. 2. Features and benefits System-level ESD protection for USB 2.0 and SuperSpeed USB 3.2 at 10 Gbps, HDMI, DisplayPort, eSATA and LVDS Line capacitance of only 0.2 pF maximum for each channel Outstanding system protection: extremely deep snapback combined with dynamic resistance of only 0.4 All signal lines with integrated rail-to-rail clamping diodes for downstream ESD protection of 15kV exceeding IEC 61000-4-2, level 4 Matched 0.5 mm trace spacing Signal lines with 0.05 pF matching capacitance between signal pairs Design-friendly pass-through signal routing 3. Applications The device is designed for high-speed receiver and transmitter port protection: Smartphones, tablet computers, Mobile Internet Devices (MID) and portable devices TVs and monitors DVD recorders and players Notebooks, main board graphic cards and ports Set-top boxes and game consolesNexperia PUSB3AB4 ESD protection for ultra high-speed interfaces 4.
