A Zener diode:

A Zener diode: Correct Answer has a sharp break-down at low reverse voltage

  • The forward voltage rating of Zener diode is the same as a normal diode
  • A zener diode is used as a voltage regulator
  • The slope (V/I) is positive
  • At reverse breakdown voltage (typically around 5V), there is a sharp breakdown at a reverse voltage as shown in the figure
