The PUSB3FR4 from Nexperia is capable of protecting high-speed interfaces, such as ports using the latest SuperSpeed USB3.1 technology, from damage caused by ESD.

As well as protecting USB interfaces carrying data at rates up to 10Gbits/s, the PUSB3FR4 is also suitable for High- Definition Multimedia Interface (HDMI), DisplayPort, external Serial Advanced Technology Attachment (eSATA) and Low Voltage Differential Signalling (LVDS) interfaces.

The device includes four high-level ESD-protection diode structures. They protect sensitive transmitters and receivers in very high-speed signal lines.

All signal lines are protected by a special diode configuration offering very low line capacitance of just 0.29pF. These diodes use a snap-back structure to provide high ESD protection to downstream components.

The device is encapsulated in a leadless DFN2510A-10 plastic package.

FEATURES

  • Up to ±15kV ESD protection for contact discharges, exceeding the requirements of the IEC 61000-4-2 standard level 4
  • Matched 0.5mm trace spacing
  • Signal lines with ≤0.05pF matching capacitance between signal pairs
  • Design-friendly pass-through signal routing

APPLICATIONS

  • Portable devices
  • TVs and monitors
  • DVD recorders and players
  • Graphics cards
  • Set-top boxes
  • Games consoles
