← TechnologyWhich outcome occurs when a MOSFET controlled thermoelectric cooler experiences gate oxide breakdown?
A)Uncontrolled thermal runaway develops quickly✓
B)The Peltier effect becomes more efficient
C)Cooling oscillates, producing inconsistent temperatures
D)Current efficiency temporarily reaches maximum
💡 Explanation
Gate oxide breakdown causes a short circuit, creating a low resistance path. Current limiting ceases, therefore, leading to uncontrolled thermal runaway rather than consistent behavior, because the short dissipates energy as heat.
