INTERNATIONAL RECTIFIER - THE POWER MANAGEMENT LEADER

The Ideal Power MOSFET for DC-DC Applications


IR’s DirectFET® MOSFETs are increasingly the preferred solution to reduce energy losses while shrinking design footprint in DC-DC applications with:
  • Highest Reliability
  • Best Thermal Performance
  • Competitive Price
  • Excellent Track Record Backed by IR Brand
  • Industry lowest on-resistance in their respective footprints
  • DirectFET – In production for 7 years
  • Industry leader in MOSFET Si technology
  • Low profile of only 0.7mm

  • Extremely low package resistance to minimize conduction losses
  • Highly efficient dual-sided cooling significantly improves power density, cost and reliability
  • Ultra low Rg and low charge minimizes switching losses
  • Integrated monolithic schottky for reduced body-diode related loss

DirectFET® Provides
Best In Class DFPR = Lowest Rdson Device

Applications:

  • VRM Modules for Servers
  • Workstations and mainframes
  • Desktops, graphic Cards
  • Notebook PCs
  • DC Switch Applications( ORing & hot swap)
