Diodes - Zener - Single

The BZX84C8V2-G3-08 are a single device that use a diode to perform the task of a Zener. These devices are also known as Zener diodes and are diodes that are specially designed to operate in the breakdown region.
A Zener diode can be constructed by adding an additional terminal to the traditional p-n junction diode. This semiconductor device has two main terminals. The cathode is typically marked with a minus(-), and the anode is typically marked with a plus (+). The central terminal is the Zener terminal.

Application field

The most common uses of a BZX84C8V2-G3-08 Zener single device are in various applications. These applications are used to regulate the voltage between two terminals, to provide over-voltage protection, to act as a reference voltage source, and to provide voltage multipliers.Zener diodes can be used in consumer electronics, such as in TVs, radios, and computers, as well as in automobile electronics. Different zener diode models are available that are designed for different operating voltages.BZX84C8V2-G3-08 Zener diodes can also be used as voltage regulators, over-voltage protectors, and other types of voltage-control components in the power supply applications.Zener diodes can also be used in surge protectors, voltage clamps, and transient suppressors to protect equipment from power surges and static electricity. They can also be used in circuits to prevent over-voltage.The BZX84C8V2-G3-08 is particularly useful in controlling and stabilizing the bias voltage in transistors, operational amplifiers, and other analog circuits. It can also be used in microcontrollers to protect against voltage spikes and help them to operate at the required voltage levels.

Working Principle

A Zener diode works by allowing the current to flow in either direction when the voltage across it is forward-biased and by establishing an avalanche breakdown region when the reverse voltage reaches the Zener breakdown voltage.The Zener breakdown voltage of a Zener diode is generally specified and is based on the semiconductor material used. The reverse direct current through the device produces a greater current density than the forward current. This higher reverse current creates an avalanche breakdown region, producing a large number of electron-hole pairs across the junction. These electron-hole pairs reduce the barriers between the materials, allowing for current to flow easily.When a Zener diode is connected in a reverse bias configuration, it can provide a constant voltage output. This is because the voltage drop across the Zener diode is reverse-biased and the breakdown voltage remains constant even when the temperature or the current changes. The constant voltage is used to stabilize the voltage, limiting the voltage and current passing through the device.
