FDH44N50

FDH44N50 — N-Channel SMPS Power MOSFET FDH44N50 N-Channel SMPS Power MOSFET 500 V, 44 A, 120 mΩ December 2013 Features Low Gate Charge Qg Results in Simple Drive Requirement (Typ. 90 nC) Improved Gate, Avalanche and High Reapplied dv/dt Ruggedness Reduced RDS(on) (110 mΩ (Typ.) @ VGS = 10 V, ID = 22 A) Reduced Miller Capacitance and Low Input Capacitance (Typ. Crss = 40 pF) Improved Switching Speed with Low EMI 175oC Rated Junction Temperature Description UniFETTM MOSFET is Fairchild Semiconductor’s high voltage MOSFET family based on planar stripe and DMOS technology. This MOSFET is tailored to reduce on-state resistance, and to provide better switching performance and higher avalanche energy strength. This device family is suitable for switching power converter applications such as power factor correction (PFC), flat panel display (FPD) TV power, ATX and electronic lamp ballasts.
