Diodes - Zener - Single are types of diodes used for establishing a reference voltage threshold. The VLZ5V1A-GS08 is one such component whose application field and working principle is discussed in this article.

Description

The VLZ5V1A-GS08 diode is a low capacitance/high current zener, housed in a SOD-323F package. The package size is considerably small, making it a better fit for space-constrained PCBs. Datasheet published by the manufacturer shows that the typical Zener voltage is 5.0V, with a range of 4.7V to 5.6V. It is rated for 250mW, with a maximum operating temperature of 125 degrees Celsius. The reverse voltage breakdown voltage is typically 4.3V and the total capacitance is just 11pF. This impressive combination of features means that the VLZ5V1A-GS08 is one of the most widely used diodes for establishing a reference voltage threshold.

Application Field

The VLZ5V1A-GS08 diode is widely used in analog and digital electronic circuits and systems. Whenever a constant voltage threshold is required, the VLZ5V1A-GS08 can be used. For example, it can be used as a reference voltage in charge pump circuits, precision clippers, analog switches, voltage regulators, ESD protection systems, DC-DC converters, power supply circuits, digital-to-analog converter circuits, and more. Additionally, the low package profile of the VLZ5V1A-GS08 makes it a perfect fit for small form-factor circuits and hand-held products.

Working Principle

When the applied voltage of a diode reaches the breakdown voltage, the device enters reverse breakdown mode. This forces a large amount of current to flow through the component, resulting in overvoltage protection. Diodes such as the VLZ5V1A-GS08 are specially designed for such functions, as they can withstand high power and temperature levels. In the VLZ5V1A-GS08, Zener breakdown occurs when the applied voltage reaches 5.0V or higher. The voltage remains constant throughout the operation, due to the low junction capacitance of this component.

Conclusion

In conclusion, the VLZ5V1A-GS08 diode is an effective component for establishing constant voltage thresholds. Its compact size and high power rating make it an ideal component for analog and digital circuits. As such, the VLZ5V1A-GS08 can be used in a wide range of applications ranging from DC-DC converters to ESD protection systems.
