N-channel 40 V, 1.2 mΩ standard level MOSFET in LFPAK88
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.
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
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

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.
