Diodes - Zener - Single

PLZ39D-HG3/H is a type of single zener diode which is used in circuits mainly for voltage regulation or voltage reference purposes. These components are designed to be connected in reverse biased mode and thus display a specific regulated voltage that remains relatively constant over varying currents. These components are usually found in circuits that require stabilization of voltage in order to protect sensitive components like radio-frequency amplifiers, logic gates, and integrated circuits.

Application Field

PLZ39D-HG3/H single zener diodes are used in a wide variety of electronic devices and applications. Their primary function, as mentioned before, is voltage regulation. As such, they are used in linear and switching power supplies, battery chargers, automotive and industrial systems, and healthcare equipment. They are also used in over-voltage protection and over-current protection circuits. PLZ39D-HG3/H diodes can be used effectively in signal conditioning applications where signals need to be attenuated or isolated from each other.

Working Principle

PLZ39D-HG3/H single zener diodes, when reverse-biased, exhibits a certain regulated voltage. This regulated voltage is down to the Zener effect which basically works by allowing the majority carriers to tunnel through the junction and become the minority carriers and thus conduct electricity. As the voltage increases beyond the PN junction\'s breakdown voltage, the current increases rapidly and this is the point at which the Zener effect kicks in. The voltage regulator holds the voltage at a constant level, regardless of the current, which is the primary purpose of these components.

An important feature of these components is their ability to limit the voltage when connected in series. This function is key in providing over-voltage protection and is commonly used in power supplies and other power circuits. It is also used in high frequency RF and signal conditioning applications.

PLZ39D-HG3/H single zener diodes are used in many different applications more that require a constant regulated voltage. They are key components in linear and switching power supplies, battery chargers, automotive and industrial systems, and healthcare equipment. They also offer reliable means of providing over-voltage protection and high frequency signal attenuation or isolation.
