Which performance issue indicates avalanche breakdown in a Zener diode circuit?

💡 Explanation

Uncontrolled current increase signifies avalanche breakdown because impact ionization releases numerous carriers at the p-n junction when exceeding reverse voltage limits; therefore the uncontrolled current characterizes failure, rather than stable recovery or predictable forward characteristics.
