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 USB3.2 due to VRWM = 2.8 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 2.8 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

  • USB4, USB3.2 and Thunderbolt 3 and 4 data lines

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
