For a p-n junction normal diode and a Zener diode, which of the following statements is true?

• A

  The Zener diode has thicker depletion region and normal diode has higher electric field across the junction.
• Correct answer
  B

  The normal diode has thicker depletion region and Zener diode has higher electric field across the junction.
• C

  The Zener diode has thicker depletion region and higher electric field across the junction:
• D

  The normal diode has thicker depletion region and higher electric field across the junction.

Hence, the correct answer is option: 'B'.
