Which consequence escalates when exceeding the reverse breakdown voltage of a p-n junction diode under high-frequency switching?

💡 Explanation

Avalanche breakdown occurs because high reverse voltage accelerates electrons across the depletion region, impacting atoms, thereby rapidly increasing current; therefore, excess heat leads to thermal runaway and device destruction, rather than improved performance.
