VLZ20D-GS18 application field and working principle

The VLZ20D-GS18 series of Zener diodes are single, low-voltage regulator diodes specifically designed for use in various integrated circuits. They provide an easily adjustable and reliable source of regulation to maintain the combined voltage of a complex system in the desired range. The device can use also be used as a dual voltage gate for switching functions and as a voltage limiter.

The VLZ20D-GS18 is suited for operating at low voltage, usually up to 3.3 volts, which is extensively used in circuits that process digital signals. The total power dissipation of the device is 74mW, which is enough to ensure efficient operation even at high currents.

In terms of functionality, the VLZ20D-GS18 acts as a Shunt regulator, in which the potential difference between its anode and cathode is kept separate from the bias current setting. It also has a built in capacitor to help regulate the output voltage and reduce current ripple. The device also works at high frequency, with an effective frequency of up to 150kHz.

When it comes to usage, the VLZ20D-GS18 is most commonly used in logic circuit designs that have a wide variety of applications. It is also used in circuits that control the supply of power to another device, such as voltage regulators and temperature controllers. Since it operates at low voltage, it is well suited for use in battery powered devices some of which require a stable voltage output.

The general working principle of the VLZ20D-GS18 is relatively simple. When a positively charged current is applied to the anode terminal of the device, the internal diode structure begins to conduct. This causes current to flow from the anode to the cathode and sets up a reverse-biased potential across the terminals. This in turn causes the current to reduce, which reduces the voltage at the anode terminal. As the anode current reaches a certain value, the device is said to be in the breakdown mode. During this mode the device stops conducting current and the voltage remains stable. This phenomenon is known as Zener breakdown and is the main principle of operation used by the VLZ20D-GS18.

Overall, the VLZ20D-GS18 is a reliable and efficient single, low-voltage regulator diode that offers an easy-to-adjust and dependable source of regulation for a wide range of applications. Additionally, it is well-suited for use in battery powered devices and operates at a high frequency with efficient current ripple limiting capabilities.
