Features and benefits

  • Bidirectional ESD protection of one line
  • ESD protection up to ±14 kV contact discharge according to IEC 61000-4-2
  • Backwards compatible to USB 3.2 due to VRWM = 4 V
  • Extremely low diode capacitance: Cd = 0.16 pF at 1 MHz
  • Extremely low clamping and trigger voltage (Vt1 = 6.9 V TLP) to protect sensitive transceivers
  • Extremely low insertion loss: -0.29 dB at 10 GHz
  • Extremely low return loss: -20.6 dB at 10 GHz
  • RF performance does not degrade over the operation voltage range
  • Extremely low leakage current: < 1 nA at 4 V
  • Extremely low inductance protection path to ground
  • Very high surge robustness: 5.5 A for a 8/20 µs pulse
  • IEC 61000-4-4 robust up to level 3 on I/O ports (corresponds to 40 A into a 50 Ohm termination)
  • Ultra-small SMD package


  • Cellular handsets and accessories
  • Portable electronics
  • Communication systems
  • Computers and peripherals
  • HDMI 2.1 and 2.0, USB4, USB 3.2 and Thunderbolt 3 and 4 data lines
