    Question

    A Zener diode differs from a regular diode in that:

    A It can conduct in forward direction only Correct Answer Incorrect Answer
    B It gets damaged if reverse biased Correct Answer Incorrect Answer
    C It maintains a constant voltage in breakdown region Correct Answer Incorrect Answer
    D It blocks both forward and reverse currents Correct Answer Incorrect Answer

    Solution

    A Zener diode is specifically designed to operate in the reverse breakdown region without damage. Unlike regular diodes, which get damaged when reverse biased beyond a certain point, Zener diodes are constructed to maintain a nearly constant voltage across them once the breakdown voltage is reached. This unique characteristic makes them ideal for voltage regulation applications, where a stable output voltage is needed despite fluctuations in load current or input voltage.
