BUK7Y1R0-40N

N-channel 40 V, 0.97 mOhm, Standard level MOSFET in LFPAK56

Automotive qualified N-channel MOSFET using the latest Trench 15 low ohmic enhanced-Trench Bottom Oxide (e-TBO) technology, providing high ruggedness at low RDSon, housed in an LFPAK56 package. This product has been fully designed and qualified to meet AEC-Q101 requirements delivering high performance and endurance.

Features and benefits

  • Fully automotive qualified to AEC-Q101:

    • 175 °C rating suitable for thermally demanding environments

  • Trench 15 e-TBO technology:

    • Merging benefits of Superjunction technology (high ruggedness) and Split-Gate technology (low RDSon)

  • Fast and efficient switching with high damping and low spiking

  • Tight VGS(th) limits enable easy paralleling of MOSFETs

  • LFPAK Gull Wing leads:

    • High Board Level Reliability absorbing mechanical stress during thermal cycling, unlike traditional QFN packages

    • Visual (AOI) soldering inspection, no need for expensive x-ray equipment

    • Easy solder wetting for good mechanical solder joints

  • LFPAK copper clip technology:

    • Improved reliability, with reduced Rth, RDSon and package inductance

    • Increases maximum current capability and improved current spreading

Applications

  • 12 V automotive systems

  • Motor, lighting and solenoid control

  • Reverse battery protection

  • Ultra high-performance power switching

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.
