Q2 Class HiPerFET™ MOSFETs feature switching efficiencies that enable high frequency operation and small power supplies. These devices combine the advantages of a low gate charge with a double-metal construction, resulting in a line of MOSFETs with an intrinsic gate resistance that is much lower than seen in conventional MOSFETs.

Features:

  • International standard packages
  • Double metal process for low gate resistance
  • Avalanche energy and current rated
  • Fast intrinsic rectifier
  • Low package inductance

Applications:

  • DC-DC converters
  • Battery chargers
  • Switched-mode and resonant-mode power supplies
  • Pulse generation
  • Laser drivers

Advantages:

  • Easy to mount
  • High power density
  • Space savings
