A diode-zener is an electrical component that finds its use as a voltage regulator. The single type of this component consists of a standard p–n junction that is reverse biased. In contrary to a normal diode, these break down or conduct when the voltage across it goes beyond its rated value. The molecule responsible for the breakdown is none other than Pyridine, which is a three-membered aromatic nitrogen-containing ring. This component creates low parallel resistance, which is further enhanced by the series resistance of diodes, like that of VDZT2R2.7B as well.

VDZT2R2.7B, also known as a Zener diode, is a component belonging to this same variety of components. Its application fields are mostly related to the functions of voltage regulators, voltage multipliers, power supplies, and transformers. This component, with a rated current of 2.7A and a rated voltage of 20V (2 R2) is capable of regulating the voltage in circuits to prevent component damage from occurring from over-voltages. It also helps to maintain a constant output voltage.

The working principle of this component, like all the other varieties of zener diode, is rather simple. As the device, in general, consists of a p–n junction, it follows the same instructions as any normally biased diode. When the reverse bias of a zener breaks down, it conducts. This conducting quality, together with its parallel resistor, works up as a voltage regulator to avoid overvoltage situations, or to manage constant output voltages.

VDZT2R2.7B, having its junction temperature of 150 ºC and a power dissipation rate of 0.3W, the device can be used to regulate small electronics and appliances in which the resistors may heat up or malfunction due to the application of a higher voltage than what the appliance can handle. This component, along with its other varieties, thus acts as a protective device for small electronic devices and circuits, allowing them to be safe from damage caused by excess voltage.

In conclusion, it can be said that the VDZT2R2.7B zener diode is quite a useful component in the electrical field, being particularly employed in the functioning of voltage regulators, voltage multipliers and power supplies. With an easy to understand working principle, the device works as a handy little protective device, which helps to regulate voltages in order to avoid damages to components in an electrical circuit.
