Extremely low capacitance unidirectional ESD protection diode array

This unidirectional ESD protection device is designed to protect high-speed interfaces such as SuperSpeed USB 3.2, HDMI, DisplayPort, external Serial Advanced Technology Attachment (eSATA), Low Voltage Differential Signaling (LVDS), and Gigabit Multimedia Serial Link (GMSL) Serializer/Deserializer (SerDes) against ElectroStatic Discharge (ESD).

The device is encapsulated in a leadless small DFN2510A-10 (SOT1176-2) plastic package and provides ESD protection up to 15 kV exceeding IEC 61000-4-2 level 4 and fulfilling ISO 10605.

Features and benefits

  • Unidirectional ESD protection for four signal lines

  • VRWM = 3.3 V device

  • Extremely low clamping voltage to protect sensitive I/Os

  • Extremely low clamping voltage: 2.8 V for 8 A 100 ns TLP and 4.4 V for 16 A 100 ns TLP

  • IEC 61000-4-4 robust up to 36 A into a 50 Ohm termination (1.8 kV)

  • IEC 61000-4-5 (surge): IPP = 8.2 A peak pulse (average measured)

  • Typical line capacitance of only 0.29 pF

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

  • Leadless ultra small DFN2510A-10 (SOT1176-2) surface mount package

  • Qualified according to AEC-Q101 and recommended for use in automotive applications


  • Infotainment applications: USB 2.0, USB 3.2 and HDMI 2.1

  • Automotive A/V monitors, display and cameras

  • SerDes: GMSL, APIX, FPD-Link and LVDS

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.
