Which outcome occurs when a MOSFET array operates continuously beyond its safe operating area?

💡 Explanation

Thermal runaway causes escalating current and heat because temperature increases conductivity; as temperature increases, the `positive feedback mechanism` drives transistor failure. Therefore catastrophic burn-out results, rather than improved operational characteristics or gate-oxide enhancement at high temperatures.
