Which outcome occurs when a bipolar junction transistor (BJT) experiences temperature-induced avalanche breakdown?

💡 Explanation

A thermal runaway begins because increased temperature raises intrinsic carrier concentration, leading to greater leakage current across the collector-base junction; resulting in increased current flow therefore causes more heating, rather than stabilized operation or mere performance degradation.
