Choosing the right SiC device for your application requires careful consideration of several factors:
Determine if you need a SiC MOSFET (for switching applications) or SiC diode (for rectification applications). SiC MOSFETs offer low switching losses, while SiC diodes provide zero recovery losses.
Select a device with a voltage rating appropriate for your application - typically 1.2x the maximum operating voltage. SiC devices are particularly advantageous in higher voltage applications.
Consider both continuous and peak current requirements. For MOSFETs, lower RDS(on) reduces conduction losses but may increase switching losses.
SiC devices excel at high-frequency operation due to their superior switching characteristics. Higher frequencies enable smaller passive components.

Compare SolutionsSiC devices offer several advantages over silicon: higher switching frequency capability with lower losses, higher temperature operation, higher voltage capability, and better thermal conductivity. These properties allow for smaller, more efficient, and more reliable systems.
SiC MOSFETs are used for switching applications where you need to control current flow actively. SiC diodes are used for rectification applications where unidirectional current flow is required. SiC diodes have zero reverse recovery losses, making them ideal for high-frequency rectification.
For SiC MOSFETs: voltage rating (VBR), on-resistance (RDS(on)), gate charge (Qg), and thermal resistance. For SiC diodes: voltage rating (VBR), current rating (IF), and forward voltage drop (VF). The specific requirements will depend on your application's power level, switching frequency, and thermal constraints.
