Q17 of 37 Page 1

Zener diode is used in reverse bias. When its reverse bias is increased, how does the thickness of the depletion layer change?

When a Zener diode is reverse biased, the depletion layer becomes wider. If this reverse biased voltage across the diode is increased continually, the depletion layer becomes more and more wider. At the same time, there will be a constant reverse saturation current due to minority carriers.
