UF3C/SC – Low RDS SiC FETs for Improved Efficiency and Lower Losses

UF3C/SC – Low RDS SiC FETs for Improved Efficiency and Lower Losses

The UnitedSic introduced UF3C/UF3SC series SiC FETs, which is designed based on a unique cascade configuration to provide higher switching speeds, higher efficiency, and lower losses. At the same time, they also offer a ‘drop-in’ replacement solution for most TO-247-3L IGBT, Si-MOSFET and SiC-MOSFET parts. This helps in making system upgrades for greater performance and efficiency without changing the existing gate circuitry. The turn-on losses can be reduced based on a 50% reduction in Qrr. For high current use, a small, low-cost RC snubber is required, which also simplifies EMI design.


Features of UF3C/UF3SC series

  • 650V and 1200V
  • Low RDS (on) from 7mohm to 150mohm
  • Excellent body diode performance(Vf<2V)
  • Drive with any Si and/or SiC gate drive voltage
  • Integrated ESD and gate protection
  • Full Suite of industry-standard packages- TO-220-3L, D2PAK-3L, TO-247-3L &-4L(Kelvin)


This UF3C/UF3SC FET series has nearly 20 FETs each ranging from an RDS (on) value of 7mohm to 150mohm and ID max ranging from 31A to 120A.
