Diodes - Zener - Single: VLZ2V7-GS08 Application Field And Working Principle

The VLZ2V7-GS08 is a single Zener diode, part of a family of single diodes that also includes Schottky and Si-based rectifier diodes. The core purpose of this diode family is to control the power supply generated within an electronic circuit. They are most commonly used in converters, UPS and other power supplies, PDAs, transceivers, and commercial rectifier-capacitor designs.

The maximum working voltage for the VLZ2V7-GS08 is 220V with a maximum controlled power of 0.5W and a voltage drop of 2V. It offers a reliable and robust solution for applications that require a lower voltage level than the input voltage. The maximum junction temperature of the diode is 125 °C and its additional features include low series resistance, good regulatory characteristics and a low capacitance junction.

The working principle of the VLZ2V7-GS08 single Zener diode is quite simple. The current that passes through the diode is limited by a voltage regulator or automated control circuit. When the input voltage exceeds the Zener voltage, a reverse bias is applied to the diode that allows current to pass through it without creating heating or dissipating energy. The diode regulates this voltage through the adjustment of its internal parameters, preventing it from exceeding the preset voltage level.

The power supply generated within an electronic circuit is determined by the leakage current, reverse current and forward current of the diode. The forward current is limited by the high breakdown voltage of the diode, while the reverse current is governed by the Zener voltage. The leakage current is determined by the junction barrier potential of the diode. All of these parameters affect the output voltage of the diode.

The maximum rated current for the VLZ2V7-GS08 is 0.6A and the maximum temperature coefficient is 0.3%. It is a hermetically sealed diode, with a power dissipation of 75mW and an operation temperature range of -55°C to 150°C. It has an extremely low reverse current of 1μA and an ultra-low leakage current of 0.01μA. The inherent benefits of using this diode include low thermal resistance, wide temperature range, high reliability, and low power consumption.

Overall, the VLZ2V7-GS08 single Zener diode is an excellent choice for applications that require a reliable, robust and efficient system to regulate the power supply within an electronic circuit. It provides improved efficiency with a low voltage drop and a regulated output voltage. Furthermore, its operational temperature range and leakage current are extremely low, making it a perfect solution for a wide variety of applications.
