The DE-SERIES Fast Power MOSFETs are a new class of unique high-power devices designed as a circuit element from the ground up for high speed, high frequency, high power applications. This Fast Power TM technology features low insertion inductance (≈2nH), and a low profile low-cost plastic package, with a RthJC as low as 0.08ºC/W, which provides exceptional switching speeds and power handling capabilities.

The DE-SERIES offer 10 times the speed and 3 times the power dissipation, with 1/2 the volume, 1/3 the weight and greatly reduced die stress, of comparable conventional power MOSFET devices.

The DE-SERIES employs the most electrically, mechanically and thermally advanced high-speed device design available today. The combination of silicon die and packaging make the DE-SERIES the device of choice for high power, high-speed applications.

  • Isolated Substrate
    • high isolation voltage (>2500V)
    • excellent thermal transfer
  • Increased temperature and power cycling capability
  • IXYS advanced low Qg process
  • Low gate charge and capacitances
    • easier to drive
    • faster switching
  • Low RDS(ON)
  • Very low insertion inductance
  • No Beryllium Oxide (BeO) or other hazardous materials

Switching Speed: ≤HF, RF MOSFET devices and ≈5 -10 times faster than conventional MOSFETs.

Frequency: Equal to many HF, RF devices and at least 5-10 times higher than conventional MOSFETs.

High gain: Approximately 3 times higher than HF, RF MOSFET devices.

Power Dissipation: Approximately twice that of HF, RF MOSFET devices and over 3 times higher than conventional MOSFET devices.

High Power Surface mount design: This allows the device to be loaded on to the PCB with all the other components in a high or low power configuration, simplifying mechanical assembly of the system.

Lowered Mechanical Stress: The device floats on the thermal compound such that the mounting hardware will not induce further package stress.

Low Inductance Packaging: The DE-SERIES has the lowest insertion inductance of any equivalent power device.

Economical High Power Mounting: The mounting configuration does not require machining of the PCB or an expensive clamping mechanism.

  • Class C, D, and E High Power Generators
  • RF Power Amplifiers
  • High-Frequency SMPS
  • Induction Heating
  • Laser Diode Drivers
  • High-Speed Pulse Generators
