CoolSiC™ MOSFET in Easy 1B, 2B

Combining the strengths of two great Infineon products: the Easy package, a bench-mark in low stray inductance and the 1200 V CoolSiC™ MOSFET enables customers to significantly reduce their system and operational costs. With regard to topology, these products meet the demand for EV charging applications such as high-frequency operation and large output variation of the DC-DC power stage.

Target applications

  • EV-Charging
  • DC/DC converter 
  • Welding
  • High Frequency Switching application
  • UPS systems 
  • Solar applications
