← TechnologyWhich outcome occurs when a high voltage transient surpasses an LED's breakdown voltage?
A)Reverse recovery switches anode/cathode
B)Avalanche multiplication causes junction breakdown✓
C)Increased thermal conduction into substrate
D)Radiative recombination pathway is enhanced
💡 Explanation
Avalanche multiplication leads to junction breakdown, causing permanent damage to the LED because the high electric field accelerates electrons which collide with atoms to generating hole-electron pairs. Therefore, LED fails catastrophically, rather than increased conduction within the semiconductor material itself.
