N-channel 40 V, 0.55 mOhm, 500 Amps continuous, standard level MOSFET in LFPAK88 using NextPowerS3 Technology
500 Amp continuous current, standard level gate drive, N-channel enhancement mode MOSFET in LFPAK88 package. NextPowerS3 family using Nexperia’s unique “SchottkyPlus” technology delivers high efficiency and low spiking performance usually associated with MOSFETs with an integrated Schottky or Schottky-like diode but without problematic high leakage current. NextPowerS3 is particularly suited to high efficiency applications at high switching frequencies, and also safe and reliable switching at high load-current.
Features and benefits
500 Amp continuous current capability
LFPAK88 (8 x 8 mm) LFPAK-style low-stress exposed lead-frame for ultimate reliability, optimum soldering and easy solder-joint inspection
Copper-clip and solder die attach for low package inductance and resistance, and high ID (max) rating
Ideal replacement for D2PAK and 10 x 12 mm leadless package types
Qualified to 175 °C
Meets UL2595 requirements for creepage and clearance
Avalanche rated, 100 % tested
Low QG, QGD and QOSS for high efficiency, especially at higher switching frequencies
Superfast switching with soft body-diode recovery for low-spiking and ringing, recommended for low EMI designs
Unique “SchottkyPlus” technology for Schottky-like switching performance and low IDSS leakage
Narrow VGS(th) rating for easy paralleling and improved current sharing
Very strong linear-mode / safe operating area characteristics for safe and reliable switching at high-current conditions
Applications
Brushless DC motor control
Synchronous rectifier in high-power AC-to-DC applications, e.g. server power supplies
Battery protection and Battery Management Systems (BMS)
eFuse and load switch
Hotswap / in-rush current management

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.
