Diodes - Zener - Single: GDZ15B-HG3-18 Application Field and Working Principle

Zener diodes, also commonly known as avalanche diodes, are a type of diode that is used for voltage regulation, latching, and other related uses. These diodes have the ability to maintain a fairly steady voltage when the current passing through them increases. The GDZ15B-HG3-18 zener diode is a single device that is used in a wide variety of applications, including regulating voltage, overvoltage protection, low noise generation, and more.

The GDZ15B-HG3-18 is a 2.0 V device. It has a maximum power dissipation of 500 mW, maximum forward voltage drop of 1.0 V at 5.0 mA, and a junction temperature of 175°C. The zener noise measured at 11Mhz is 30mV. In order to achieve the best results from the device, it should be installed in a 15 ohm series resistor network. This resistor network will help to maintain the diode\'s stability.

The general working principle of the GDZ15B-HG3-18 is based on the principle of avalanche breakdown. When current is passed through the diode, it begins to increase in voltage, until it reaches the breakdown voltage. Once the diode reaches the breakdown voltage, it prevents further increases in voltage by allowing a regulated amount of current to pass. This regulated amount of current is what keeps the voltage at a constant level.

The GDZ15B-HG3-18 is typically used in applications such as voltage regulator, overvoltage protector, low-noise generator, and double-effect zener. When used as a voltage regulator, the GDZ15B-HG3-18 helps to ensure that the output voltage remains constant at a specific level, even when the input voltage spikes or changes. This is vital in applications where fluctuations in voltage can potentially cause damage to sensitive circuitry. The diode is also used as an over-voltage protector, as it will regulate the current passing through the diode and prevent it from exceeding a certain level.

When used as a low-noise generator, the GDZ15B-HG3-18 helps to reduce the amount of noise generated from the circuits. This helps to ensure that the signal and noise levels remain constant, even in situations where the signal and noise levels can spike, such as when the device is used in a switching power supply. Lastly, the GDZ15B-HG3-18 can be used as a Double-Effect Zener. When the output voltage begins to exceed the breakdown voltage, the diode\'s internal voltage-current characteristics come into play, and the current will be regulated to keep the output voltage at a constant level.

Overall, the GDZ15B-HG3-18 is a powerful and versatile diode that can be used for a wide range of applications. Its voltage-current characteristics make it ideal for use as a voltage regulator, over-voltage protector, low-noise generator, and double effect zener. Additionally, the device is capable of maintaining a steady voltage when the current passing through it increases, and its 15 ohm resistor network helps to ensure optimal performance, stability, and safety.
