MMBZ4698-G3-08 Application Field and Working Principle

MMBZ4698-G3-08 is a single Zener diode that bridges the gap between conventional and semiconductor devices. This device is designed to perform a certain function by controlling the flow and distribution of electricity, where electricity is present in either an AC or DC format. The diode has a voltage breakdown rating of 8V and a maximum power dissipation of 0.5W.

Application Field of MMBZ4698-G3-08

The main application field of the MMBZ4698-G3-08 is that it is most commonly used as an overvoltage protection diode. The diode’s properties allow it to regulate the current flow and limit the voltage to the required level. It is frequently used as protection against transients, power surges and ESD (electrostatic discharge). As with general diodes, the MMBZ4698-G3-08 can also be used for rectification and signal control in AC/DC voltage applications.

Working Principle of the MMBZ4698-G3-08

The MMBZ4698-G3-08 is a Zener diode. It has a lower breakdown voltage than conventional diodes. As such, it is used in applications where it is necessary to maintain a low voltage level. The working principle of a Zener diode is based on the increased density of electrons at the junction within the semiconductor material. In the rest state of a MMBZ4698-G3-08 diode, no current flows through it and no electric field exists in the interior of the diode. When the diode is forward biased, holes and electrons combine in the junction region and give rise to the flow of current. When the diode is reverse biased, the electric field in the junction region increases until it reaches the breakdown voltage of the diode (in this case 8V). The increased electric field then causes many electrons to break free from their respective atoms and free charges start to flow through the diode in the reverse direction, resulting in a current that is limited by the resistance of the diode. As a result, the voltage across the diode is controlled and kept at the breakdown voltage level.

Conclusion

The MMBZ4698-G3-08 is a Zener diode with a breakdown voltage rating of 8V and maximum power dissipation of 0.5W. It is commonly used in a variety of applications to regulate voltage levels or for protection against transients, power surges and ESD (electrostatic discharge). Its working principle is based on the increased density of electrons at the junction within the semiconductor material, which causes an electric field to form when the diode is reverse biased and will cause current to flow through the diode until the breakdown voltage is reached.
