BZX84C6V2ET1

Diodes - Zener - Single

BZX84C6V2ET1 is a type of single zener diode. It is a member of the Standart Voltage Regulator Diode Family, obtained in a wide range of voltage values. It is designed specifically for regulating and controlling zener operating parameters. The main application field of this model is in battery chargers, relay sensors, power supplies, automotive applications, parallel switchover networks and multiplexer systems.

Working Principle

For this particular diode model, its best working condition occurs when reverse bias is applied across it, allowing the depletion region to form, which is filled with the flow of minority carriers. This implies that the current passing through the diode is blocked until the Breakdown Voltage Vbr is reached. At this point, the availability of a low resistance path towards the anode allows current to flow unrestricted, which is called Zener breakdown or avalanche. As a consequence, voltage is maintained even if the value of the current increases.

The overall stability of the diode also depends on the electrical characteristics of the connected components. This means that when the surrounding components are changed, the voltage regulation of the diode will be affected. For this reason, it is necessary to modify the value of the resistor connected in series with the diode to fulfill the desired voltage regulation parameters.

Applications

BZX84C6V2ET1 can be used in a wide range of applications, such as automatic voltage regulation in small switching power supplies, rectifiers, multiplexers, and linear data converters. It is also widely used in automotive power systems, as a replacement for zener diodes in a variety of automotive circuits and modules, as an amplifying and regulating device in electronic circuits, and in lighting applications.

Furthermore, this type of diode has been successfully used in the production of Tesla coils, which require a stable voltage regulation to produce a high voltage output. Additionally, the diode has been used in the development of home-made digital voice recorders, thanks to its ability to regulate circuit output, as well as for the production of low-cost temporary sensors for automotive systems.
