Diodes - Zener - Single

Zener diodes, also known as Avalanche diodes, are devices which are used to regulate voltages; in this particular case, the UDZLVTE-17110 is used to regulate voltages between 2.4 and 2.6 Volts with a compliance current range of 17mA to 110mA.

The UDZLVTE-17110 is a very small, two-lead device, making it an attractive choice for applications with limited space. It has a zener impedance of 140mW, allowing it to be used in higher-power applications, and the unit can handle up to 800mA of surge current, allowing it to handle sudden voltage spikes. The device is based on low-voltage breakdown technology, making it a suitable choice for a range of applications, such as protection for circuits against transient or temperature-based voltage irregularities.

Application Field

The UDZLVTE-17110 can be used in a variety of applications, including: over-voltage protection in industrial, automotive, and medical applications; voltage control in embedded systems and smart phones; and to prevent over-voltage damage in high-precision devices such as quartz watches. It can also be used as an access control device, controlling the voltage of a circuit, and it can also be used to improve the accuracy of linear voltage regulators.

Working Principle

A Zener diode operates on the principle of low-voltage breakdown. This occurs when, in a reverse-biased diode structure, an electric field is applied across the structure, exceeding the diode\'s maximum breakdown voltage. This causes an avalanche effect, where electrons are injected into the depletion region, creating a high current flow. This current lowers the electric field across the junction, allowing for a stable reverse-biased region. The UDZLVTE-17110 is a special type of Zener diode, made from a lightly-doped semiconductor material in order to improve the diode’s ability to produce a low-voltage breakdown.

Conclusion

In conclusion, the UDZLVTE-17110 is a two-lead Zener diode which operates on the principle of low-voltage breakdown, making it suitable for a range of applications, including over-voltage protection, voltage control, and access control. Its improved material construction makes it more suitable for a variety of applications in the industrial, automotive and medical fields, as well as its use in embedded systems and quartz watches.
