Question
The leakage current across a pn junction is due to _________
The leakage current across a pn junction is due to _________
Open in App
Solution
The correct option is A Minority carriers
When a diode is reverse biased, its depletion region increases in width. Thus depletion region would correspond to an insulator. However still some current actually flows through the depletion region. This is due to the pushing of minority carriers across the depletion region causing very small reverse 'leakage current'.
