Infineon — CFD7 Family of CoolMOS™ Superjunction MOSFETs

Infineon has extended its CFD7 family of CoolMOS™ superjunction MOSFETs with new 650V-rated devices which offer high efficiency and power density in soft-switching industrial power supplies. The new parts offer an extra 50V of breakdown-voltage headroom over the existing range of 600V CFD7 MOSFETs. 

The 650V CFD7 MOSFETs are notable for the fast integrated body diode, low reverse-recovery charge for improved switching performance, and excellent thermal behavior. The robust architecture makes the MOSFETs suitable for use in hard-commutation applications. The extra safety margin over 600V-rated MOSFETs is also helpful in designs which operate on a high bus voltage.

The CFD7 devices offer the best on-resistance ratings of any 650V MOSFET in a TO-247, TO-220, or D2PAK package. These ratings vary little over temperature.

The high light- and full-load efficiency and low power losses provided by the CFD7 MOSFETs in soft-switching topologies enable system designers to increase power density while maintaining high reliability in industrial applications which have a long operating lifetime.
