Introduction

BZG05C68-E3-TR3 is a single Zener diode, which is widely used in many electrical circuit applications. It is highly efficient and robust and offers a wide operating range that is suitable for a variety of applications. In this article, we will discuss the application fields and working principle of BZG05C68-E3-TR3.

Application Field

BZG05C68-E3-TR3 is often used in voltage regulator circuits. In these circuits, it functions by regulating the voltage output from the power supply to maintain a constant voltage level. This ensures that any appliance connected to the circuit is provided with a stable power supply. Other application fields include clamping applications, transient voltage protection, and diode bridge circuits.

BZG05C68-E3-TR3 is also used in many AC/DC converters, where it functions as a low-cost alternative to costly active components. It is also used in high frequency switching power supplies, which benefit from its ability to sustain high current and voltage levels without dissipating excessive power.

Working Principle

A Zener diode is a two-terminal device with a single pn junction. It works by allowing current to flow from its anode to its cathode, when a forward bias voltage is applied. Its current flow reverses, when the applied voltage reaches a certain level, known as the breakdown voltage, or the Zener voltage. After the voltage reaches this threshold, the current flow through the diode remains constant, regardless of any further increase in voltage.

The principle of the BZG05C68-E3-TR3 can be further explained with a graph. As shown in the below figure, when the applied voltage is below the Zener voltage, the current flowing through the diode follows the same pattern as a conventional diode. As the voltage approaches the breakdown voltage, the current surges, before stabilizing at the Zener current. Beyond the breakdown voltage, the current remains almost constant.

The Zener diode can also be operated in a reversed bias direction. Here, it functions as a voltage regulator, by preventing any voltage above the breakdown voltage from appearing across its terminals. This makes them ideal for use in circuit protection applications.

Conclusion

BZG05C68-E3-TR3 is a single Zener diode that is used in many electrical circuit applications. Its application fields include voltage regulator circuits, clamping applications, transient voltage protection, and diode bridge circuits. It functions by allowing current to flow from its anode to its cathode, when a forward bias voltage is applied. When the voltage reaches a certain level, known as the breakdown voltage, or the Zener voltage, the current flow through the diode remains constant, regardless of any further increase in voltage.
