Given below are two statements:
Statement I: A Zener diode is always connected in reverse bias when used as a voltage regulator.
Statement II: The breakdown voltage of a Zener diode decreases with an increase in doping concentration. Choose the correct answer from the options given below:
Options:
Answer:
A
Solution:
Statement I is true. A Zener diode is designed to operate in the reverse breakdown region to maintain a constant voltage across its terminals, making it suitable for voltage regulation.
Statement II is also true. Higher doping concentration leads to a narrower depletion region and a stronger electric field for a given reverse voltage, which causes breakdown to occur at a lower voltage.
