Which failure mode is most likely in SiC Schottky diodes when reverse blocking voltage increases rapidly?

💡 Explanation

Local thermal runaway is likely because inhomogeneous current distribution worsens with fast-changing blocking voltages due to the positive temperature coefficient; therefore, the diode can fail from overheating rather than uniform avalanche breakdown across its area.
