Diodes - Zener - Single: VLZ30D-GS08 Application Field and Working Principle

The VLZ30D-GS08 is a single Zener diode made by ON Semiconductor that has a relatively active application field in a variety of contemporary circuits. Examples of such circuits include voltage references and voltage limitation, reverse polarity protection, and power clamping. In this article, we’ll dive deeper into the application fields and working principles of the VLZ30D-GS08.

Features of VLZ30D-GS08

The VLZ30D-GS08 is a single Zener diode with an operating temperature range of -65°C to +175°C, which makes it a suitable choice of device for a wide variety of application fields. It is also a low-power device, with a maximum operating temperature at 25°C and 0.5 watts of power. It is a two layer device, with a P-type layer, and an N-type layer. Its terminal capacitance is 2.2 pF at a reverse voltage of 5 volts.

Applications of VLZ30D-GS08

The VLZ30D-GS08 is most notably used as a voltage reference device. When connected in parallel to a resistive load, heat generated is dissipated via the two-layer construction of the diode and the Joule effect. If a voltage is placed across the diode, the current will flow in such a way that the diode drops the voltage across the resistor by a known value. This is an efficient way of creating a voltage reference that is stable and reliable.The VLZ30D-GS08 can also be used as part of a reverse polarity protection circuit. When the device is connected between a voltage source and ground, the low leakage current of the diode limits the amount of current that can flow in the event of a reverse polarity connection. With the electrical protection that it provides, the VLZ30D-GS08 makes it suitable for use in a wide range of electrical equipment and systems.Finally, the VLZ30D-GS08 can be used as part of a power clamping circuit. The device can be used to limit the voltage across a load and protect other elements of the circuit from overvoltage. This is done by allowing the diode to conduct when the voltage across the load reaches a certain level, thus clamping the voltage level and protecting the circuit from further damage.

Working Principle of VLZ30D-GS08

The VLZ30D-GS08 works by a process known as Zener breakdown. When a voltage is applied to the P-N junction of the device, the Zener effect occurs, which is the result of a rapid increase in current. At this point, the diode can drop the voltage across the resistor to a more stable value, thus providing a voltage reference.At low voltages, the two terminals of the diode act as a simple rectifier, allowing current to flow in one direction only. If the voltage across the diode reaches the breakdown voltage (approximately 3 volts for the VLZ30D-GS08) the P-N junction breaks down and allows for the current to flow in both directions. This process is known as Zener breakdown, and it’s what allows the device to act as a voltage reference and voltage limiter. As the voltage across the diode increases, the amount of current also increases exponentially in a phenomenon known as the Zener knee. This phenomenon is used in power clamping circuits, as it can allow the diode to quickly clamp the voltage level, thus protecting the circuit from overvoltage. In summary, the VLZ30D-GS08 is a single Zener diode with a wide application field and highly reliable operation. It can be used in voltage reference, reverse polarity protection, and power clamping circuits, due to the Zener breakdown effect encountered in the device at high voltages. This breakdown allows for current to flow in both directions and for a voltage reference or limitation to be formed.
