... To decide the current rating of a SiC diode, there is a rule of thumb - the SiC diode can handle output power POUT of 100W to 120W in a CCM-PFC-system per one rated ampere. For example, the IDH04S60C from Infineon Technologies is rated at a continous forward current, IF = 4 A, so it is capable for a ...
