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


  • 12 V automotive systems
  • 48 V DC/DC systems (on 12 V secondary side)
  • Higher power motors, lamps and solenoid control
  • Reverse polarity protection
  • LED lighting
  • Ultra high performance power switching
