Diodes - Zener - SingleSingle Zener diodes are a type of diode that is used for voltage regulation or voltage reference. A Zener diode is a specialized diode that is designed to operate in the reverse-breakdown region, where the voltage across the diode is constant regardless of the current flowing through the diode. This behavior allows the Zener diode to be used as a voltage regulator or voltage reference, providing a stable voltage output. Single Zener diodes are commonly used in applications where it is necessary to provide a stable voltage reference or to protect circuits from overvoltage conditions. These diodes are typically small and inexpensive, making them a popular choice for use in a wide range of applications. Single Zener diodes are also available in a variety of voltage ratings, allowing them to be used in a wide range of applications with different voltage requirements.
