PZU9.1DB2, 115 application field and working principle belong to the category of diodes - zener - arrays

A diode array is an electronic component that is made up of multiple individual diodes arranged in a well-defined pattern on a single chip. The pattern in which the diodes are arranged is determined by the type of diode array being used. Diodes used in diode arrays are typically PN junction diodes that are designed for specific functions.

Zener diodes are a type of diode that is designed to allow current to flow in the forward direction, much like a traditional diode. However, they are unique in that they can also allow current to flow in the reverse direction when the voltage across their terminals exceeds a predetermined threshold voltage, known as the Zener voltage. In effect, Zener diodes act as a kind of backstop that prevents excessive voltages from damaging other components.

One application for diode arrays, including Zener arrays, is in power supply design where multiple Zener diodes can be used to provide a range of different voltages for different components in the system. Similarly, diodes can be used in series or in parallel in order to provide different levels of current. Diode arrays can also be used to provide protection from over-current, over-voltage, or over-temperature conditions.

PZU9.1DB2, 115 is a 9.1 volt Zener diode array that contains three Zener diodes (D1, D2, and D3). Each diode is rated at 400 mW, with a maximum reverse voltage of 9.1 volts and a maximum reverse current of 115 mA. The total power rating is 1.2 watts.

The working principle of Zener diode arrays is relatively straightforward. When the voltage across the terminals of the diode exceeds the breakdown voltage (VZ) of the diode, the diode begins to conduct in the reverse direction. This reverse current limits the voltage across the terminals of the diode to the breakdown voltage, thus providing protection from over-voltage. The amount of current allowed to flow through the diode will depend on the breakdown voltage of the diode and the amount of current available.

In addition to providing protection from over-voltage, Zener diode arrays can also be used to provide a constant voltage output for use in circuits such as voltage regulators. In such cases, the Zener diodes are used in a voltage regulation circuit, where the circuits output is maintained at a constant voltage, regardless of changes in the input voltage.

In summary, PZU9.1DB2, 115 is a 9.1 volt Zener diode array that is used in power supply design and circuit protection. The device consists of three Zener diodes, each rated at 400 mW, with a maximum reverse voltage of 9.1 volts and a maximum reverse current of 115 mA, providing a total power rating of 1.2 watts. The components of the diode array work together to limit the voltage across the terminals of the diode to the breakdown voltage, thus providing protection from over-voltage, as well as a constant voltage output for use in circuits such as voltage regulators.
