CZRU52C4V7 Application Field and Working Principle

The CZRU52C4V7 Zener diode is part of the NXP series of standard zener diodes, a single discrete diode with a power rating of 500mW that can rectify and protect the output current, and represent highly stable and reliable rectifying components.

The CZRU52C4V7 provides a reverse voltage of 4V, an operating temperature range of -55°C to +150°C, and a precise voltage rating of ±5%. It also features a forward voltage drop of 1.5 V and a breakdown voltage of 6.1 V, as well as a small reverse current of 2.5 µA.

CZRU52C4V7 can be used in real-time electrical machinery control systems, cars, or in the circuit protection of sound equipments that require precision and stability. As the temperature increases, the stability of the leakage current of the CZRU52C4V7 does not change drastically. Therefore, this diode is suitable for controlling voltage stabilization and for suppressing voltage fluctuation in occasions when there is an increase in temperature.

The working principle of the CZRU52C4V7 is similar to that of other zener diodes. Voltage passes through this diode, creating a flow of electrons from the Anode to the Cathode. When the cathode voltage reaches the zener voltage, the zener Starts to conduct. As the current increases, the diode breaks down, creating a sharp rise in the current, producing a voltage drop in response.

As the voltage drops, a portion of the current is diverted away from the desired load, and increased current is supplied through the Cathode-Regulator junction. The current will be kept under control by the self-regulating mechanism, until the voltage of the anode is stabilized at the designated voltage level. After that, the voltage can be used to regulate other electrical equipments and maintain their stability.

CZRU52C4V7 is a popular choice for the application of overvoltage protection, because of its affordability and its high tolerance for power fluctuations. It is frequently used in AC/DC adapters, battery chargers, and other applications with a wide range in voltage; as well as in photoresistors, as its photosensitivity is very high.

The CZRU52C4V7 is an indispensable part of electronics and is ideal for stabilizing and protecting circuits from surges, spikes, and other electrical disturbances. Its accurate voltage control and reliability makes it a reliable option for the regulation and protection of electrical circuits.
