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