BUK7V4R2-40H

Dual N-channel 40 V, 4.2 mOhm standard level MOSFET in LFPAK56D (half-bridge configuration)

Dual, standard level N-channel MOSFET in an LFPAK56D package (half-bridge configuration), using Trench 9 TrenchMOS technology. This product has been designed and qualified to AEC-Q101.

An internal connection is made between the source (S1) of the high-side FET to the drain (D2) of the low-side FET, making the device ideal to use as a half-bridge switch in high-performance automotive PWM applications.

Features and benefits

  • LFPAK56D package with half-bridge configuration enables:

    • Reduced PCB layout complexity

    • PCB shrinkage through reduced component footprint for 3-phase motor drive

    • Improved system level Rth(j-amb) due to optimized package design

    • Lower parasitic inductance to support higher efficiency

    • Footprint compatibility with LFPAK56D Dual package

  • Advanced AEC-Q101 grade Trench 9 silicon technology:
    • Low power losses, high power density
    • Superior avalanche performance

    • Repetitive avalanche rated

  • LFPAK copper clip packaging provides high robustness and reliability

  • Gull wing leads support high manufacturability and Automated Optical Inspection (AOI)

Applications

  • 12 V automotive systems

  • Powertrain, chassis, body and infotainment applications

  • Brushless or brushed DC motor drive

  • DC-to-DC systems

  • LED lighting

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.
