1.1 General description
The device is designed to protect high-speed interfaces such as SuperSpeed USB, 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 for ultra high-speed signal lines and 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 0.5 pF. These diodes utilize a unique snap-back structure in order to provide protection to downstream components from ESD voltages up to 10 kV contact exceeding IEC 61000-4-2, level 4.
1.2 Features and benefits

Product data sheet Rev. 1 — 10 May 2017 8 of 14 Nexperia PUSB3F97 ESD protection for ultra high-speed interfaces The device uses an advanced clamping structure showing 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 DC current sources to the data lines to avoid keeping the ESD protection device in snap-back state after exceeding breakdown voltage (due to an ESD pulse for instance).
