Why is the depletion region in a Zener diode significantly narrower compared to a regular P-N junction diode?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1Because the P region is heavily doped while the N region is extremely lightly doped.
- 2Because Zener diodes are fabricated using completely different semiconductor materials.
- 3Because of the heavy doping of both P and N regions in a Zener diode.✓
- 4Because the doping of P and N regions in a Zener diode is lighter than in a regular diode.
Correct answer
Because of the heavy doping of both P and N regions in a Zener diode.
