Which outcome occurs when a transient voltage exceeds the avalanche breakdown voltage of a Zener diode regulating a power supply?

💡 Explanation

Diode short-circuit happens because the avalanche breakdown mechanism causes uncontrolled current flow, leading to heat and failure. Therefore, the diode short-circuits, clamping the surge, thereby protecting downstream, rather than allowing voltage increase or forward current shift.
