← ScienceWhich risk increases significantly when transient overvoltages exceed semiconductor breakdown?
A)Electrostatic discharge component failure✓
B)Increased thermal runaway propensity
C)Dielectric fatigue accelerates noticeably
D)Barrier capacitance degradation occurs rapidly
💡 Explanation
Electrostatic discharge failure emerges because the dielectric breakdown causes sudden, uncontrolled current flow. The mechanism of breakdown is impact ionization. Therefore, semiconductor failure results rather than thermal runaway because the field overwhelms the designed junctions.
