Very low capacitance unidirectional ESD protection diode array

Extremely low capacitance unidirectional ElectroStatic Discharge (ESD) protection diode array, part of the TrEOS protection family. This device is housed in a DFN2510-10 (SOT1165-3) leadless ultra small Surface-Mounted Device (SMD) plastic package, designed to protect four signal lines from the damage caused by ESD and other transients.

Features and benefits

  • Unidirectional ESD protection for four signal lines

  • VRWM = 3.3 V device

  • Extremely low clamping voltage to protect sensitive I/Os

  • IEC 61000-4-5 (surge): IPP = 7.9 A peak pulse (average measured)

  • Extremely low diode capacitance Cd = 0.29 pF typical at 1.5 V

  • ESD protection up to ±15 kV according to IEC 61000-4-2

  • Leadless ultra small DFN2510-10 (SOT1165-3) surface mount package


  • Cellular handsets and accessories

  • Portable electronics

  • Communication systems

  • Computers and peripherals

  • USB3.2 data lines

As a Nexperia customer you can order samples via our sales organization.

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. Check out the list of official distributors.

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.
