← TechnologyWhich effect emerges during high-frequency operation, when a Schottky diode's junction is not fully depleted, leading to reduced switching speed?
A)Reverse recovery time increase
B)Forward voltage overshoot develops
C)Capacitive charging delay increases✓
D)Avalanche breakdown voltage decreases
💡 Explanation
Increasing depletion region width modulation introduces a `Capacitive charging delay` because of the increased capacitance and resistance. Therefore, switching speed is limited, rather than immediate reverse recovery, because full depletion is required for optimal performance below breakdown.
