In the realm of electronics, Zener diodes stand out as remarkable components known for their ability to maintain a consistent voltage across their terminals, regardless of variations in current flow. Acting as voltage regulators, these diodes find applications in diverse electronic circuits, from power supplies to voltage reference circuits, where stable voltage levels are crucial. Their distinct characteristics, including a sharp reverse breakdown voltage and a controlled avalanche region, make them indispensable for ensuring reliable voltage regulation and protection against voltage surges.
