Ultra-Junction X-Class Power MOSFETs with fast body diodes are rugged devices that display the lowest on-state resistances in the industry, enabling very high power density in high-voltage power conversion applications. Developed using the charge compensation principle and proprietary process technology, these devices exhibit low gate charges and superior dv/dt performance. In addition, thanks to the fast soft-recovery body diode, these Ultra-Junction MOSFETs help reduce switching losses and electromagnetic interference (EMI).

Features:

  • Ultra low on-resistance RDS(ON) and gate charge Qg
  • Fast body diode
  • dv/dt ruggedness
  • Avalanche rated
  • Low package inductance
  • International standard packages

Advantages:

  • Higher efficiency
  • High power density
  • Easy to mount
  • Space savings

Applications:

  • Industrial switched-mode and resonant-mode power supplies
  • Electric vehicle battery chargers
  • AC and DC motor drives
  • DC-DC converters
  • Renewable-energy inverters
  • Power Factor Correction (PFC) circuits
  • Robotics and servo control
