PESD2ETHAX-Q

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 = 1.8 pF

  • IEC 61000-4-2 up to 12 kV

  • ISO 10605 (330 pF, 2 kΩ) up to 15 kV

  • Very low reverse current

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

Applications

  • 100BASE-T1 / OPEN Alliance BroadR-Reach automotive Ethernet

  • Low-Voltage Differential Signaling (LVDS) automotive

  • USB 2.0 automotive

Sample

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.
