Introduction

1N4689 TR is a single Zener diode that has been widely used in various applications. In this paper, we will discuss the application field and working principle of 1N4689 TR.

Application Field

1N4689 TR has been widely used in various applications such as voltage regulation, surge protection and battery protection. In the field of voltage regulation, 1N4689 TR can be used to maintain a steady output voltage in the event of a large input voltage fluctuation. This is achieved by using the Zener effect, which occurs when the reverse breakdown voltage of the diode is exceeded. The diode will conduct a current proportional to the voltage drop across it so that the output voltage remains fairly constant.1N4689 TR can also be used as surge protection. It can be used to limit the magnitude of a transient high-voltage surge, which could otherwise damage component circuitry. When the transient voltage exceeds the Zener voltage of the diode, it will start to conduct, redirecting the energy away from the component circuitry and thus protecting it from damage.1N4689 TR can also be used in battery protection. It can be used to limit voltages to a safe range, preventing damage to the battery cells. The 1N4689 TR can also prevent overcharging and over discharging of the battery.

Working Principle

1N4689 TR is a Zener diode, which operates according to the Zener effect. The Zener effect occurs when the reverse breakdown voltage of the diode is exceeded. This results in a large amount of current flowing through the diode and a large drop in the voltage of the device. When the Zener diode is connected in reverse bias across a load, the diode will operate in the breakdown region when the voltage is greater than the diode\'s breakdown voltage. The diode will then start to conduct, dropping the voltage across the load to the Zener voltage.The Zener voltage of 1N4689 TR is 7.8V. This means that when it is connected in reverse bias, it will conduct when the voltage across it exceeds 7.8V and it will drop the voltage to 7.8V. The 1N4689 TR has a maximum power rating of 0.3W, which means that it is suitable for low-power applications only.

Conclusion

1N4689 TR is a single Zener diode that has been widely used in various applications such as voltage regulation, surge protection and battery protection. It operates according to the Zener effect, which occurs when the reverse breakdown voltage of the diode is exceeded. The Zener voltage of 1N4689 TR is 7.8V, with a maximum power rating of 0.3W.
