FLZ20VA Application Field and Working Principle

FLZ20VA is a single, Zener diode, which is commonly used in the circuit design and voltage management. Typically, Zener diodes provide a constant voltage level regardless of the changes in the current input, in order to protect other circuit components from voltage spikes and overvoltage. The FLZ20VA features high power and excellent stability, making it the ideal choice for a variety of different applications. In this article, we will discuss the application field and working principle of FLZ20VA in more detail.

Application Field

The FLZ20VA is usually used in power supply design, in lieu of multiple Zener diodes in series, to achieve variable and adjustable voltage. Specifically, the FLZ20VA is commonly applied to voltage regulation, voltage clippings and clipping circuits, as well as in digital integrated circuits. Other possible application fields of the FLZ20VA include voltage-sensitive logic circuits, power LCD displays, computer devices, audio amplifiers, and voltage converters. Aside from this, the FLZ20VA is often used in power electronics or DC-DC converters and AC-DC converters, where it serves as a voltage peak clamp, as well as in low power surge protection.

Working Principle

FLZ20VA\'s working principle relies on the P-N junction diode or a diode formed by a two-layer semiconductor crystal, whereby the area of N-type material functions as the anode and the area of P-type material acts as the cathode. As a result, the FLZ20VA exhibits its Zener breakdown, wherein the reverse conduction of current occurs at a particular reverse-bias voltage level. As the FLZ20VA has a relatively large Zener impedance, it is still able to conduct Zener current at a fixed voltage level, even when the primary bias voltage increases.

Due to a wide range of breakdown voltages, it is possible to use the FLZ20VA in AC coupled applications. In this type of application, the diode serves as a bypass, directing a part of the current away from the circuit, while the other part of the current still circulates within the circuit. Such application is particularly useful in the protection of sensitive components, since it enables the circuit to operate with a lower level of current surge.

Conclusion

In summary, the FLZ20VA is a versatile single Zener diode, which offers high power and excellent stability in a wide range of applications. As evidenced, it can be used for voltage management, voltage clippings, voltage-sensitive logic circuits, power LCD displays, and computing devices. Aside from this, the FLZ20VA is able to provide protection from voltage spikes and overvoltage through its reliable Zener breakdown effect. All in all, the FLZ20VA is a powerful and reliable circuit component, which is well-suited to a wide array of different applications.
