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.

The device 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.

Features and benefits

  • ESD protection of two high-speed data lines
  • Ultra low capacitance: Cd = 1 pF
  • IEC 61000-4-2 up to 8 kV
  • Very low reverse current
  • AEC-Q101 qualified


  • 100BASE-T1/OPENAllianceBroadR-ReachautomotiveEthernet
  • Low-Voltage Differential Signaling(LVDS)automotive
  • USB2.0 automotive
