GDZ20LP3-7 Application Field and Working Principle

GDZ20LP3-7 is commonly referred to as a single Zener diode. Its application field is to provide a stable, low noise power supply for electronic systems, especially those with high frequency operation requirements. It is widely used in television receivers and computers, etc. It employs a variety of crystal technologies in order to make the diode stable and reliable, hence increasing its lifetime. With the sort of technical expertise with which it is designed, the diode can be used up to a maximum operating temperature of 120℃.

Working Principle

The working principle is slightly different than that of a regular diode. It is configured to act as a voltage reference. The most common type of Zener diode is a two-terminal device that consists of an anode (A) and a cathode (K). When a reverse bias is applied to it, electrons are forced to move through a very thin region of a semiconductor called the •depletion layer•. The depletion layer acts as a barrier between the anode and the cathode, thus preventing current from flowing through it. At a certain reverse bias voltage, Zener breakdown occurs and the barrier is broken allowing a large current to flow through the diode.

Once the Zener breakdown occurs, the current is maintained in a very narrow band due to the constricted Zener voltage. The Zener voltage is the voltage at which the diode can sustain a certain reverse bias current. Basically, once the required voltage is achieved, the current flow is maintained at a much higher level with minimal variation, thus providing a stable and reliable power supply.

Modular Design

The individual components used for the design of the GDZ20LP3-7 are usually split into two parts. The first part consists of the Zener diodes and the other consists of the capacitors and resistors used in order to stabilize the power supply.

The Zener diodes are generally based on the most popular Silicon GiFET or now a-Si/SiGe technology. As mentioned above, they are reverse-biased elements that act as voltage regulators and provide a stable, low noise power supply. The other components, such as the capacitors and resistors, are used to provide additional stabilization or to reduce any power distortion.

Conclusion

In conclusion, the GDZ20LP3-7 single Zener diode is a reliable and stable power supply device. It employs modern Silicon GiFET or a-Si/SiGe technology for its various components and is made to endure temperatures up to 120℃. It is widely used in various electronic systems and provides a low noise power supply for various high-frequency applications.
