Introduction

The 3EZ6.8D/TR12 is a Zener diode which is a single junction diode. This type of diode is designed to let electricity flow in one direction, and when the voltage exceeding a certain value called zener voltage, the current will start to increase in reverse direction. This diode is most commonly used in the fields of power supply, cathode ray tubes, rectifiers, and etc. In this article, we will discuss the application fields and working principles of 3EZ6.8D/TR12.

Application field

3EZ6.8D/TR12 diodes are generally used in power supplies and voltage regulation system. In most power supplies, diodes play a critical role in providing a steady and reliable output voltage. It enables the device to produce a steady output voltage that may be free from noise or other disturbances. The main application of this type of diode is in regulating the current flow in the device, which is especially important when the current is highly dynamic or oscillating.The diodes can also be used in some other applications such as cathode ray tubes for television and computer monitors, field restricts, and RF power control applications. They are also used in voltage converting and regulating circuits, rectifiers applications and low-noise audio amplifiers. In addition, they can also be used in a wide range of telecom applications such as line drivers, signaling, and as protection of telephone lines.

Working principle

The 3EZ6.8D/TR12 operates on a simple principle: when the voltage across the diode reaches its zener voltage, the diode begins to conduct in the reverse direction. This reverse current tends to keep the voltage across the diode at a given level, regardless of any changes in the input voltage. This stabilization is achieved due to the diode’s circuit design which creates an impedance that allows the reverse current to flow and maintain the desired output voltage.In simple words, the 3EZ6.8D/TR12 will first start to conduct when the voltage across it reaches its zener voltage. This then creates a stabilizing resistance and current to maintain the desired output voltage.

Conclusion

The 3EZ6.8D/TR12 is a single junction zener diode. It is mainly used for power supply, cathode ray tubes, rectifiers and other applications which require voltage regulation. It operates by allowing a current to pass in reverse direction when the voltage across it reaches the pre-defined zener voltage, and provides stabilization of the output voltage. Owing to the wide range of applications, the 3EZ6.8D/TR12 has become an essential component in multiple commercial products.
