Diodes - Zener - Single Application Field and Working Principle

A single zener diode, also known as a zener diode or avalanche diode, is a diode that allows current to pass in reverse direction once it has attained a certain reverse voltage known as the zener voltage. When the reverse voltage exceeds the zener voltage, the diode will conduct electricity in both directions, creating a voltage drop across its terminals. This voltage drop can be used to regulate a supply voltage. DFLZ12Q-7 is a single zener diode that has a breakdown voltage of 12V.

Application Field

Single zener diodes are used in a variety of applications, the most common being voltage regulation. They are commonly used to provide a stable voltage that is independent of the load current, allowing them to maintain a fixed output voltage while the input voltage varies. Additionally, they are used to stabilize signals, and as safety devices in overvoltage protection circuits.

The DFLZ12Q-7 is mainly used as a voltage regulator and for overvoltage protection. It can be used in a variety of situations ranging from AC and DC power supplies to automotive systems and telecommunications. It has a reverse voltage of 12V, and a power rating of 500mw. It is mainly used for low-voltage applications, and is suitable for use in both through-hole and surface-mount circuit designs

Working Principle

Zener diodes are designed to operate in the breakdown region, meaning that they behave like a normal diode when the reverse voltage is less than the breakdown voltage. When the reverse voltage exceeds this threshold, the breakdown region is entered, and the zener diode begins to conduct current in both directions. This creates a voltage drop across the device, resulting in a regulated output voltage. Zener diodes have a relatively low reverse breakdown voltage, so they must be operated at low currents in order to achieve the desired output voltage.

The DFLZ12Q-7 is an ideal device for voltage regulation and overvoltage protection. It is designed to have a reverse voltage of 12V, and will begin to conduct current in both directions when the reverse voltage reaches this point. This will result in a voltage drop across the device, creating a regulated output voltage. The power rating of the diode is 500mw, so it should be operated at relatively low currents in order to ensure that the output voltage remains constant.

Conclusion

The DFLZ12Q-7 is a single zener diode, which is suitable for use in a variety of applications, including voltage regulation and overvoltage protection. It has a reverse breakdown voltage of 12V, and a power rating of 500mw. When operated at low currents, the diode will create a voltage drop across its terminals, providing a regulated output voltage.
