BUK7S1R2-40H N-channel 40 V, 1.2 m standard level MOSFET in LFPAK88 6 August 2020 Product data sheet 1. General description 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. 2. 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 DPAK for todays 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 R DSon Low source inductance Low thermal resistance R th 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 R in the same footprint DSon Improved SOA and avalanche capability compared to standard TrenchMOS Tight V limits enable easy paralleling of MOSFETs GS(th) 3. 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 LED lighting Ultra high performance power switching 4.
