VLZ3V3B-GS18 diodes are single Zener diode devices, which are used for controlling and regulating voltage. Such diodes can be found in a number of electronics, from cell phones to car audio systems, from computer motherboards to power supplies of low voltage AC or DC. This type of diode is used to ensure a steady and consistent voltage level, which helps in protecting the circuit and its components from sudden variations in voltage.

Fields of Application

The VLZ3V3B-GS18 is an ideal diode for a range of applications due to its high current and power capabilities.It is designed to regulate the input voltage in excess of 3V while providing maximum current of around 1.8A. It is also designed to be employable in battery-powered systems and can be used in the control of half-bridge converters and power supplies.

The VLZ3V3B-GS18 is used in appliances such as microwaves, coffee makers, steam irons, and toaster ovens, as well as in automotive applications ranging from airbag triggers to car alarms and also smoke detectors. This diode is ideal for protecting these appliances with a consistent voltage level and in different power conditions.

Working Principle

Single Zener diodes regulate voltage by utilizing the voltage’s natural response. The diode reverses the polarity of the current so that the positive guardrail comes in contact with the negatively charged ‘cathode’. As a result, the voltage rises until the voltage from both sides of the current circuit is equal. This equalized voltage is known as the Zener voltage, which serves as the limit beyond which the current cannot advance.

Since the VLZ3V3B-GS18 has a Zener voltage of 3V, this implies that if the input voltage exceeds 3V, then the diode will limit the current by cutting it off, thereby preventing an overload. The current will then reach a steady state, where the input voltage, although reduced, still has enough power to cause the current to travel in a cycle, without an increment of the current.

Conclusion

The VLZ3V3B-GS18 single Zener diode is one of the most broadly used diodes in the industry. Its wide range of applications makes it suitable for a variety of electronic needs. Not only that, but its ability to regulate the input voltage to 3V and provide a maximum current of 1.8A, makes it a powerful and reliable device for various appliances.
