What is silicon carbide diode?

The diodes we usually use are mostly made of silicon. With the development of technology, the most popular silicon carbide diodes recently are those made of silicon carbide.

Currently, the most common type is high-voltage Schottky silicon carbide diodes.

Its advantages: 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 disadvantages such as low ability to withstand surge currents and low reliability. But there has been significant improvement so far.
