What is silicon carbide diode?

Usually, the diodes used by most people are made of silicon as the raw material, but the recently popular silicon carbide diodes are those made of silicon carbide as the raw material.

Currently, the commonly used high-voltage Schottky silicon carbide diodes have the advantage of excellent reverse recovery characteristics, comparable to Schottky silicon diodes. But it can be used as a high-voltage diode.

It has been widely used in PFC. Disadvantage: The forward conduction voltage drop is relatively large. Another difference from silicon diodes is that their conduction voltage drop increases with temperature. Early silicon carbide diodes had drawbacks such as low ability to withstand surge currents and low reliability, but significant improvements have been made so far.
