N-channel 40 V, 7.0 mΩ standard level MOSFET in LFPAK56
Automotive qualified N-channel MOSFET using the latest Trench 9 low ohmic superjunction technology, housed in a robust LFPAK56 package. This product has been fully designed and qualified to meet AEC-Q101 requirements delivering high performance and endurance.
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

Sample
As a Nexperia customer you can order samples via our sales organization.
If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.
How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
