FDH44N50 - N-Channel SMPS Power MOSFET

General 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.

Key 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.
