PUSB2X4D ESD protection for high-speed interfaces Rev. 1 — 5 November 2013 Product data sheet 1. Product profile 1.1 General description The device is designed to protect high-speed interfaces such as USB 2.0 ports against ElectroStatic Discharge (ESD). The device includes four high-level ESD protection diode structures for high-speed signal lines. It is encapsulated in a small SOT457 (SC-74) Surface-Mounted Device (SMD) plastic package. All signal lines are protected by a special diode configuration offering ultra low line capacitance of 0.85 pF maximum. This configuration provides protection to downstream components from ESD voltages up to 12 kV contact according to IEC 61000-4-2, level 4. 1.2 Features and benefits System ESD protection for USB 2.0 All signal lines with integrated rail-to-rail clamping diodes for downstream ESD protection of 12 kV according to IEC 61000-4-2, level 4 Line capacitance of 0.85 pF maximum for each channel 1.3 Applications The device is designed for receiver and transmitter port protection in: Portable devices TVs, monitors DVD recorders and players Notebooks, mother boards, graphic cards and ports Set-top boxes and game consoles

ESD protection for high-speed interfaces Dynamic resistance with positive clamping; typical values Dynamic resistance with negative clamping, typical values tp = 100 ns; Transmission Line Pulse (TLP) tp = 100 ns; Transmission Line Pulse (TLP) Dynamic resistance with positive clamping, typical values Dynamic resistance with negative clamping; typical values The device uses an advanced clamping structure, which shows a negative dynamic resistance. This snap-back behavior strongly reduces the clamping voltage to the system behind the ESD protection during an ESD event. Do not connect unlimited...
