Focus:
In Infineon's third-generation SiC Schottkys diodes, a new die-to-package mounting technology improves steady-state thermal resistance and transient thermal impedance, which allows a given die to run cooler or permits use of a smaller die size for a given current rating. The latter option leads to lower device capacitances. Article discusses the impact of 3rd gen 600-V SiC schottkys on power factor correction (PFC) application using a 1000-W CCM PFC converter to demonstrate an improvement in light-load efficiency. Article also discusses how 1200-V 3rd gen SiC Schottkys are beneficial as freewheeling diodes for ultrafast IGBTs, enabling lower losses or higher switching frequencies in applications suchs as solar power inverters.
