Read the following statements regarding a Zener diode: (A) It is designed to operate in the reverse breakdown region. (B) To use it as a voltage regulator, it is connected in series with the load resistance. (C) Its depletion region is very thin due to the heavy doping of both p and n regions. (D) In the breakdown region, a large change in voltage produces an insignificant change in current. How many of the above sta

Step-by-step solution

Statement (A) is correct because a Zener diode is specifically designed to operate under reverse bias in the breakdown region. Statement (B) is incorrect because a Zener diode is connected in parallel with the load resistance to act as a voltage regulator. Statement (C) is correct as the heavy doping of both p and n sides results in a very thin depletion region (less than 10⁻⁶ m ). Statement (D) is incorrect because in the Zener breakdown region, a large change in current through the diode produces an insignificant
