ESD protection for ultra high-speed interfaces
21 August 2018
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 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, 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 0.29 pF for each channel • Outstanding system protection: extremely deep snap-back combined with dynamic resistance
of only 0.27 Ω • 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 consoles
