Ultra low capacitance double rail-to-rail ESD protection diode

Ultra low capacitance double rail-to-rail ElectroStatic Discharge (ESD) protection diode in a small SOT143B Surface-Mounted Device (SMD) plastic package.

The device is designed to protect two high-speed data lines or high-frequency signal lines from the damage caused by ESD and other transients.

PRTR5V0U2AX integrates two ultra low capacitance rail-to-rail diodes and one additional ESD protection diode to ensure signal line protection even if no supply voltage is available.


  • ESD protection of two high-speed data lines or high frequency signal lines
  • Ultra low input/output to ground capacitance: C(I/O-GND) = 1.8 pF
  • ESD protection up to 12 kV
  • IEC 61000-4-2, level 4 (ESD)
  • Very low clamping voltage due to an integrated additional ESD protection diode
  • Very low reverse current
  • AEC-Q101 qualified
  • Small SMD plastic package

Target applications

  • USB 2.0 ports
  • Digital Video Interface (DVI)
  • High-Definition Multimedia Interface (HDMI)
  • Mobile phones
  • Digital cameras
  • WAN/LAN systems
  • PCs, notebooks, printers and other PC peripherals
