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 ful y 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 D²PAK for today’s space constrained high power automotive applications • Thin package and copper clip enables LFPAK88 to be highly ef icient thermal y • 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 Gul 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 paral eling of MOSFETs 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 • Ultra high performance power switching 4.
