← TechnologyWhich outcome occurs when an LED in a series connected lighting array experiences prolonged negative voltage surpassing its reverse breakdown?
A)Photonic efficiency will improve
B)Reverse current exponentially increases✓
C)Forward voltage requirement will decrease
D)Thermal runaway is less probable
💡 Explanation
When an LED's reverse breakdown voltage is exceeded, impact ionization leads to a rapid increase in reverse current and device damage, because carriers gain enough energy to create electron-hole pairs. Therefore, reverse current surge happens, rather than improved efficiency, as this over voltage destroys the led.
