A Zener diode is specifically designed to operate safely in the reverse-bias breakdown region. When the reverse voltage reaches the Zener voltage, the diode conducts a significant reverse current while maintaining an approximately constant voltage across its terminals. This property makes Zener diodes useful for voltage regulation, reference circuits, and overvoltage protection.
A question related to a Zener diode is ______.
