← TechnologyWhich outcome occurs when avalanche breakdown arises in a silicon p–n junction designed for a voltage rectifier?
A)Uncontrolled current drastically elevates temperature✓
B)Minority carriers recombine effectively suppress leakage
C)Thermal equilibrium is retained, preventing damage
D)Depletion region enhances, blocking reverse current
💡 Explanation
Runaway results because impact ionization frees additional carriers contributing to an escalating cycle; this thermal runaway mechanism raises operating temperature until device failure, therefore leading to destruction of the rectifier junction rather than minor recombination influencing leakage currents.
