PUSB3AB4

ESD protection for ultra high-speed interfaces

The device is designed to protect high-speed interfaces such as SuperSpeed USB 3.1 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.

Features

  • System-level ESD protection for USB 2.0 and SuperSpeed USB 3.1 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 Ω
  • All signal lines with integrated rail-to-rail clamping diodes for downstream ESD protection of ±15 kV 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

Target 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
