← TechnologyWhich outcome occurs when germanium diodes exceed reverse voltage?
A)Avalanche breakdown causes current increase✓
B)Thermal runaway decreases resistance
C)Zener effect maintains voltage stability
D)Diffusion capacitance causes higher capacitance
💡 Explanation
Avalanche breakdown results when high reverse voltage accelerates electrons with sufficient energy to ionize germanium atoms, creating electron-hole pairs because the diode's electric field becomes strong, therefore leading to a sharp current increase, rather than controlled voltage via Zener effect.
