Balance between efficiency and robustness with fast body diode



Button-Find-Product-Portfolio   button-find-boards


A recent trend in high power conversion is the move toward higher and higher power density. High power density can be achieved best by resonant switching topologies such as zero voltage or zero current switching, which enable higher efficiency by eliminating the turn-on losses.


Key features Key benefits Applications
  • First 650V technology with integrated fast body diode on the market
  • Limited voltage overshoot during hard commutation
  • Significant Qg reduction compared to 600V CFD technology
  • Tighter R DS(on) max to R DS(on) typ window
  • Easy to design-in
  • Lower price compared to 600V CFD technology
  • Low switching losses due to low Q rr at repetitive commutation on body diode
  • Self limiting di/dt and dv/dt
  • Low Q oss
  • Reduced turn-on / turn-off delay times
  • Outstanding CoolMOS™ quality



Example of a ZVS based power converter using CoolMOS™ CFD2


CoolMOS™ CFD2 is Infineon’s latest series with an integrated fast body diode. It is the ideal choice for high power applications such as in telecom and server markets, in which high efficiency levels need to be reached while not compromising on highest reliability and ease-of-use.


Highest ease-of-use for fast design-in

CoolMOS™ CFD2 comes with a very low voltage overshoot and minimal ringing behaviour. Reduced gate spikes combined with the high safety margin of 200V along with enable fast design-in without the need for additional ringing control.


Higher efficiency performance in mid-load to full-load conditions

CoolMOS™ CFD2 offers efficiency benefits of up to 0.6% over competing products in the critical range of mid-load to full-load conditions.




Highest reliability from lowest reverse recovery charge and reverse reovery time

Hard commutation prevails in ZVS topologies and requires a device with excellent fast body diode performance mainly dependent on a low Q rr (reverse recovery charge) and T rr (reverse recovery time). 



The fast reverse recovery of CoolMOS™ CFD2 offers designers the benefits of

  • Reduce stress on the device while body Diode is not fully recovered and
  • Extra safety margin for repetitive hard commutation in designs which translates into reduced design-in effort

Switch Mode Power Supplies (LAB Session)

Switch mode power supplies (lab session)

 This lab session features a ZVS (zero voltage switching) phaseshift topology, a very important application of Infineon`s CoolMOS™ and OptiMOS™ families, which is widely used in high performance DC-DC converter stages, server and telecom SMPS . Infineon experts are showing details of this topology, which integrates a CoolMOS™ CFD2 and an OptiMOS™ device, and thus achieves zero voltage switching at very load light load.
