DZ23C4V3-7 Diodes - Zener - Arrays Application Field and Working Principle

Zener - Arrays, often referred to as Zener arrays, are a special type of diode arrays. Zener arrays are a form of passive semiconductor components consisting of a plurality of Zener diodes and loads connected in series or parallel. Each Zener diode can have a breakdown voltage close to a predetermined value and can appropriately adjust the thermal characteristics and junction capacitance of the diode, so as to prevent the reverse breakdown voltage of each diode from deviating too much.The DZ23C4V3-7 diode is a package of seven Zener diodes in one body. These include two Zener diodes with a rated power rating of 500mW, four Zener diodes with a rated power rating of 250mW, and one Zener diode with a rated power rating of 200mW. The Zener voltage range is from 4V to 70V, with a reverse voltage up to 80V. It is a variety of semiconductor devices available in a wide range of packaged types, for example, single, dual, triple and multiple chips. The DZ23C4V3-7 is mainly used in the following fields: 1. Output circuit of switching power supply: DZ23C4V3-7 is commonly used as the output voltage regulator for switching power supply, applicable to many kinds of electric equipments, such as computer and miniature power supply.2. Computer peripheral circuit protection: Using the characteristics of Zener diode, the circuit can be used to control the magnitude of voltage, protect the peripheral circuit, and effectively reduce the damage caused by overvoltage.3. Voltage drop: The Zener diode has the characteristics of zener breakdown. A voltage drop can be formed by connecting a resistor and a Zener diode in series. Compared with the voltage drop made by the ordinary power tube, it will not cause the working current to be too large due to the small current of the Zener diode and reduce the heat loss.4. Signal elimination and circuit isolation: Because of its good linearity, the DZ23C4V3-7 can be used in the signal elimination circuit. It can also be used in isolated circuits to separate the two circuits, which makes the interference between the two circuits very small.The working principle of the DZ23C4V3-7 is similar to that of the other Zener diodes. When the votlage across the diode exceeds a certain value (the so-called reverse breakdown voltage or Zener voltage), the diode will enter the breakdown state. In the reverse breakdown state, the diode can conduct in both directions, that is, the voltage applied to the diode is constant, and the current through the diode is adjustable. Thus, when the Zener diode works in the reverse breakdown state, it can be used to limit the voltage, and when it works in the forward direction, it can be used to form a voltage drop circuit.Overall, the DZ23C4V3-7 diode has a wide range of application fields, including the output circuit of switching power supply, computer peripheral circuit protection, voltage drop, and signal elimination and circuit isolation. Its working principle is simple, but its application value is very high. Therefore, it is widely used in the development of electronic products.
