MAZS02400L Discrete Semiconductor Products

Diodes - Zener - Single

MAZS02400L is a single, Silicon Zener diode commonly used in a variety of applications, particularly in precision rectification and as low noise references. The MAZS02400L is extensively employed for over- and undervoltage protectors, often as reference elements in voltage clamping circuits, voltage regulator circuits, and stabilizing circuits. It also finds use in many other rectifying, clipping, or clamping operations.

Working Principle

A Zener diode is a particular type of diode that offers avalanche breakdown voltage, an essential feature in the functioning of the MAZS02400L. The breakdown voltage occurs when the applied voltage across the junction of the diode exceeds a certain value, causing electron-hole pairs to be created as current begins to flow through the diode. This breakdown voltage is also known as the Zener voltage, a term derived from Clarence Zener, who had hypothesised this phenomenon in the early 1920s. When the current exceeds a certain limit, then the diode is said to be in the breakdown region, which is the "on" state for this circuit component.

The single Zener diode has two terminals, the anode and the cathode. The cathode is the negative terminal, and the anode is the positive terminal. As the potential difference across the terminals of the diode increases, the current through the diode increases exponentially, until the Zener voltage is reached. When the voltage reaches this value, the diode suddenly becomes conductive and the current flow is limited by the component\'s load. This sudden increase in conductivity is known as the Zener breakdown, and the voltage at which it occurs is the reverse breakdown voltage of the component.

Practical Application

The MAZS02400L can also be used to prevent overvoltage and undervoltage situations. By connecting a device in parallel with a power supply, the Zener diode serves to limit the amount of voltage that can be fed through onto devices connected in the same circuit, thus protecting them against damage that could be caused by an excessively high or low voltage.

Another use for the MAZS02400L is to create controlled, low-noise reference sources. By connecting the diode to a voltage source and a resistor, the component can act as a voltage regulator, limiting the voltage output to a predetermined level after the current has risen significantly beyond the Zener voltage. In cases where precision is necessary, the added thermal stability of the MAZS02400L makes it a particularly attractive choice.

The MAZS02400L can also be employed as a low-noise circuit device that can provide a controlled and stable current source to other components in established circuits. This can be done by utilising the Zener breakdown, the unique characteristics of Zener diodes that allow the right load to be placed on the device, thereby attaining the desired results.

Conclusion

As can be seen, the MAZS02400L offers remarkable results in a variety of applications. Its low leakage current, low zener impedance, and reliable breakdown voltage make it an ideal choice of component in many rectification, voltage regulation, and clamping operations, as well as providing low-noise reference sources.
