General description 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 ef iciency and low spiking performance usual y associated with MOSFETs with an integrated Schottky or Schottky-like diode but without problematic high leakage current. NextPowerS3 is particularly suited to high ef iciency applications at high switching frequencies, and also safe and reliable switching at high load-current. 2. 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 ef iciency, especial y 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 3. 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 4.
