← TechnologyWhich consequence results when excessive reverse voltage persists across a rectifier diode's P-N junction?
A)Avalanche breakdown occurs✓
B)Thermal runaway is initiated
C)Forward bias increases
D)Barrier potential decreases
💡 Explanation
Avalanche breakdown occurs because high reverse voltage accelerates minority carriers, causing impact ionization near the P-N junction, therefore increasing current abruptly rather than maintaining a stable reverse current due to increased resistance.
