BUK7S2R5-40H

N-channel 40 V, 2.5 mOhm standard level MOSFET in LFPAK88

Automotive qualified N-channel MOSFET using the latest Trench 9 low ohmic superjunction technology, housed in a copper-clip LFPAK88 package. This product has been fully designed and qualified to meet beyond AEC-Q101 requirements delivering high performance and reliability.

Features and benefits

  • Fully automotive qualified to beyond AEC-Q101:

    • -55 °C to +175 °C rating suitable for thermally demanding environments

  • LFPAK88 package:

    • Designed for smaller footprint and improved power density over older wire bond packages such as D²PAK for today’s space constrained high power automotive applications

    • Thin package and copper clip enables LFPAK88 to be highly efficient thermally

  • LFPAK copper clip technology enabling improvements over wire bond packages by:

    • Increased maximum current capability and excellent current spreading

    • Improved RDSon

    • Low source inductance

    • Low thermal resistance Rth

  • LFPAK Gull Wing leads:

    • Flexible leads enabling high Board Level Reliability absorbing mechanical and thermal cycling stress, unlike traditional QFN packages

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

    • Easy solder wetting for good mechanical solder joint

  • Unique 40 V Trench 9 superjunction technology:

    • Reduced cell pitch and superjunction platform enables lower RDSon in the same footprint

    • Improved SOA and avalanche capability compared to standard TrenchMOS

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

Applications

  • 12 V automotive systems

  • 48 V DC/DC systems (on 12 V secondary side)

  • Higher power motors, lamps and solenoid control

  • Reverse polarity 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.
