PSMNR55-40SSH N-channel 40 V, 0.55 mOhm, 500 Amps continuous, standard level MOSFET in LFPAK88 using NextPowerS3 Technology 6 April 2021 Product data sheet 1. General description 500 Amp continuous current, standard level gate drive, N-channel enhancement mode MOSFET in LFPAK88 package. NextPowerS3 family using Nexperias 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. 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 I D (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 Q , Q and Q for high efficiency, especially at higher switching frequencies G GD OSS 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 I leakage DSS Narrow V rating for easy paralleling and improved current sharing GS(th) 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.
