BUK9J0R9-40H

N-channel 40 V, 0.9 mΩ logic level MOSFET in LFPAK56E

Automotive qualified N-channel MOSFET using the latest Trench 9 low ohmic superjunction technology, housed in an enhanced LFPAK56E package. This product has been fully designed and qualified to meet AEC-Q101 requirements delivering high performance and endurance.

Features

  • Fully automotive qualified to AEC-Q101:
    • 175 °C rating suitable for thermally demanding environments
  • Trench 9 Superjunction technology:
    • Reduced cell pitch enables enhanced power density and efficiency with lower RDSon in same footprint
    • Improved SOA and avalanche capability compared to standard TrenchMOS
    • 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 joint
  • LFPAK copper clip technology:
    • Improved reliability, with reduced Rth and RDSon
    • Increases maximum current capability and improved current spreading

Target applications

  • 12 V automotive systems
  • Motors, lamps and solenoid control
  • Start-Stop micro-hybrid applications
  • Transmission control
  • Ultra high performance power switching
