Introduction

The BZX384-C75,115 (hereby referred to as "the diode") is part of a series of Zener diodes designed for general purpose applications. This series is designed to have a specific breakdown voltage (Vb) of 75 V, with a tolerance of ± 5 %. It is a single Zener diode, meaning that it consists of only one diode. It is classified as a "Low Voltage", meaning that the Vb is at or below 75 V. This diode is usually used in applications that require a stable voltage source to regulate current flow.

Application Field

The BZX384-C75,115 is primarily used in applications that require voltage regulation, such as switching power supplies, linear and switched mode power supplies, telecoms equipment, and low voltage power supplies. It is also suitable for use in both AC and DC applications. In linear mode applications, it is used to provide exceptional stability and accuracy in regulating current flow and in switched mode it is used to regulate the switching frequency. It can also be used in various telecoms applications, such as to provide a stable reference voltage in fibre optics and Ethernet networks.

Working Principle

The working principle of the BZX384-C75,115 diode is relatively simple. When the voltage applied across the anode and cathode terminals exceeds the Vb of the diode by a certain amount (normally about 0.7V for this diode type), the diode will enter the breakdown region and start conducting current. The breakdown voltage (Vb) of the diode is determined by the physical characteristics of the diode and is designed to be very stable and accurate. The diode will then regulate the current flow, ensuring that the voltage across its terminals remains constant and stable - within a certain tolerance - regardless of any changes or fluctuations in external voltages.

Advantages of the BZX384-C75,115

The main advantage of the BZX384-C75.115 is its ability to accurately and stably regulate current flow. The diode also offers high peak power ratings, making it suitable for a wide variety of applications. Furthermore, its low capacitance and high frequency response makes it ideal for high frequency applications. Additionally, the diode is designed to have a low forward voltage drop, making it more efficient than other diodes with similar breakdown voltages. Finally, it is designed to withstand surges up to 600W for 10 ms (depending on the device), making it more robust than other diodes in its category.

Conclusion

The BZX384-C75.115 diode is a low voltage, single Zener diode that is designed for general purpose applications that require voltage regulation. Its breakdown voltage of 75 V is designed to be precise, stable, and accurate. It is primarily used in switching power supplies, linear and switched mode power supplies, BZX384-C75,115 has a low forward voltage drop, allowing for greater efficiency, as well as high peak power ratings, making it suitable for a wide variety of applications.
