← TechnologyWhich outcome occurs when exceeding a Schottky diode's temperature rating?
A)Increased reverse leakage current✓
B)Drift mobility increases sharply
C)Decreased forward voltage drop
D)Carrier recombination rate decreases
💡 Explanation
Increased temperature enables **thermionic emission** across the Schottky junction, because higher thermal energy allows more electrons to overcome the barrier. Therefore, reverse leakage current spikes abruptly, rather than forward characteristics improving.
