PLZ2V2B-G3/H Datasheet/PDFDiodes - Zener - Single
The PLZ2V2B-G3/H is a single zener diode commonly used for voltage regulation and reverse polarity protection. It is designed for medium current and high frequency applications, such as switched-mode power supplies and power line filters. Its small size and low cost makes it an attractive choice for many applications.
Application Field
The PLZ2V2B-G3/H is suitable for high frequency applications like those found in modern switched-mode power supplies. It can also be used for reverse polarity protection, voltage regulator circuits, and power line filtering purposes. Typical application areas include consumer electronics, automotive, industrial, telecommunications, and medical equipment.
Working Principle
The PLZ2V2B-G3/H is a Zener diode and works on the principles of Zener effect. In simplest terms, when the voltage applied to the diode exceeds the Zener breakdown voltage, the diode rectifies the applied voltage and imposes a reverse voltage on the circuit. This ensures a stable output voltage, preventing any fluctuations. This makes it perfect for voltage regulation purposes.
The PLZ2V2B-G3/H also works as a reverse polarity protection device. When connected in reverse, the diode will provide a low impedance path to ground. This quickly drains any current that may be applied to the diode and prevents any damage to the circuit.
The PLZ2V2B-G3/H is also well-suited for use as a power line filter. It can reduce the EMI generated by switching circuits, which would otherwise interfere with other devices operating in the same frequency. Additionally, it can also absorb any spikes on the power line from external sources, which helps protect other components in the circuit from getting damaged.
Summary
The PLZ2V2B-G3/H is a single zener diode designed for medium current and high frequency applications. Its small size and low cost makes it an attractive choice for many applications. It can be used as a voltage regulator, reverse polarity protection, and a power line filter. Its Zener effect works to both regulate and protect the circuit from damage. As such, it is a great choice for many kinds of circuit designs.
