← ScienceWhich outcome occurs when exceeding the Zener breakdown voltage?
A)Increased electron-hole pair generation.✓
B)Reduced semiconductor carrier mobility.
C)Increased avalanche breakdown current.
D)Suppressed thermal runaway effects.
💡 Explanation
Exceeding the Zener breakdown voltage causes increased breakdown current via Quantum Tunneling; the electric field causes direct electron transitions across the band gap, because the depletion region is narrow; therefore higher current flows rather than limited avalanche effects occuring at higher voltages.
