BZX84C6V2ET3G

Diodes - Zener - Single

The BZX84C6V2ET3G is a single, metal-oxide-semiconductor, small-signal zener diode. It is a diode designed specifically to perform a very specific task: regulating the flow of electricity in both the forward and reverse directions. Zener diodes are widely used in many applications where precise voltage regulation is needed, such as power-supply regulation, overvoltage protection, and voltage-transition.

Application Field

The BZX84C6V2ET3G is widely used in various applications. Firstly, it is often used in power-supply regulation applications. In this type of application, the zener diode acts as a regulator by preventing the output voltage from exceeding a given level. This can be done by placing the diode in series with the load, and ensuring that the voltage applied to the diode does not exceed its breakdown voltage. In this way, any voltage above this point will be diverted away from the load and dissipated as heat.

In addition, the BZX84C6V2ET3G is sometimes used in overvoltage protection applications. In these applications, the zener diode ensures that the voltage applied to a sensitive component or circuit does not exceed a certain threshold. This is achieved by placing the diode in parallel with the component or circuit, and allowing any voltage exceeding the breakdown voltage to be diverted away.

Finally, the BZX84C6V2ET3G is also useful in voltage-transition applications. In this type of application, the zener diode is used to transition a low voltage to a higher voltage. This is done by placing the diode in series with the load, and ensuring that the voltage applied to the diode does not exceed its breakdown voltage. As the voltage exceeds the breakdown voltage the diode will conduct, slowly transitioning the voltage from a low level to the desired high level.

Working Principle

The BZX84C6V2ET3G works on the principle of avalanche breakdown. When a voltage greater than the breakdown voltage is applied to the diode a large current begins to flow. This is due to the fact that the junction is quickly depleted of all its charge carriers, resulting in an avalanche breakdown. The large current rate causes the zener diode to conduct and no further voltage is required to maintain the current.

In addition to its avalanche breakdown process, the BZX84C6V2ET3G also utilizes a property known as zener breakdown. When the voltage applied to the diode exceeds the zener voltage, a large reverse current begins to flow through the junction. This current is due to the fact that an increased electric field causes a great number of electron-hole pairs to be created, allowing a large current to pass through the diode.

The combination of the avalanche breakdown and zener breakdown make the BZX84C6V2ET3G a highly versatile and useful component. This combination allows the diode to be used in a variety of applications in which precise voltage regulation is needed.
