Power MOSFET, N-Channel, UniFETTM, 500 V, 44 A, 120 mΩ, TO-247

Favorite

Overview

UniFETTM MOSFET is a 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.

  • This product is general usage and suitable for many different applications.
  • Low gate charge Qg results in simple drive requirement ( Typ. 90nC)
  • Improved Gate, avalanche and high reapplied dv/dt ruggedness
  • Reduced RDS(on) ( 110mΩ ( Typ.)@ VGS = 10V, ID = 22A)
  • Reduced Miller capacitance and low Input capacitance ( Typ. Crss = 40pF)
  • Improved switching speed with low EMI
  • 175oC rated junction temperature
