Diodes are a type of semiconductor device that are able to control the flow of electricity in one or both directions. They are used in a variety of applications where the flow of electricity needs to be managed. When it comes to the use of diodes, Zener diodes are one of the most frequently used types. Zener diodes, also known as voltage-regulated or voltage-referenced diodes, are diodes that are designed to operate in the reverse breakdown region. This allows them to regulate voltage and provide a stable voltage source.

VLZ2V4B-GS08 is a single Zener diode manufactured by Vishay Intertechnology. It is a hermetically sealed, low-leakage, high-stability Zener diode featuring maximum Zener reverse power dissipation of 500 mW. The device has a wide variety of application fields and is suitable for most applications which do not require an exact voltage reference.

Application Field

VLZ2V4B-GS08 are suitable for most applications which do not require an exact voltage reference. It is commonly used in industrial applications such as auto components and battery-powered devices; as well as domestic applicaitons such as TV sets and camcorders. It can be used in any device that needs ruggedness, loose tolerance and accurate voltage regulation. This device is also well suited for surface mount applications due to the small size and weight.

Working Principle

The VLZ2V4B-GS08 operates in the reverse breakdown region of operation. When the voltage applied to the diode is below the specified breakdown voltage (Vz) the device will act like an open switch, blocking any current flow. When the applied voltage exceeds Vz, the device will begin to conduct current. Once the current through the device reaches a certain level (IDSS), the device will become saturated, and the current through the device will remain relatively constant, regardless of the increasing voltage. This is known as the Zener effect.

The VLZ2V4B-GS08 provides a stable voltage source, due to the presence of the Zener region. This allows it to maintain a constant voltage despite fluctuations in current and load. The device features temperature compensation, which helps it maintain its specified breakdown voltage over its applicable temperature range.
