Use MPS SiC Diodes to Minimize Losses in High-Frequency, Switched Mode Power Supplies

High-frequency switch mode circuits, such as those for power factor correction (PFC) using continuous conduction mode (CCM), require diodes that have low switching losses. For conventional silicon (Si) diodes in CCM mode, these switching losses result from the diode’s reverse recovery current due to stored charge in the diode junction during turn-off.

Minimizing these losses generally requires an Si diode with a greater average forward current, leading to a larger physical size and higher cost.
