1N5267B-TR Diodes - Zener - Single Application Field And Working Principle

The 1N5267B-TR is a current regulator diode that is found in many electronic applications. It is often used in switch mode power supplies, general power supply circuits, and in other applications where tight voltage regulation is important. The 1N5267B-TR is a Zener diode, meaning that it operates in a reverse bias configuration and can be used to regulate the output voltage of a circuit. In this article, we will discuss the application field and working principle of the 1N5267B-TR.The 1N5267B-TR is a three-terminal, low-current Zener diode. Its design and structure allow it to maintain a very low reverse leakage current and a very tight breakdown voltage. The maximum voltage rate of the 1N5267B-TR is 40V, and the maximum allowable reverse current is 200mA. This diode is also capable of withstanding high temperature extremes, making it suitable for high-power applications.In its application field, the 1N5267B-TR is most commonly used in switch mode power supplies and general power supply circuits. In a switch mode power supply, the diode is used to regulate the output voltage by providing a stable output voltage regardless of fluctuations in the input. The 1N5267B-TR can also be used as a voltage regulator in general power supply circuits, where it can regulate the output voltages to avoid overvoltage and undervoltage conditions. To understand how the 1N5267B-TR works, we must first understand the working principle of a Zener diode. A Zener diode is a type of diode that is designed specifically to operate in a reverse bias configuration. In this configuration, an electric field is formed in the diode when a voltage is applied to it that is greater than its breakdown voltage. This electric field causes the current in the diode to decrease, creating a stable and predictable output voltage that is determined by the breakdown voltage of the diode.The breakdown voltage of the 1N5267B-TR is 4.7V, meaning that when a voltage greater than 4.7V is applied to the diode, its current will be reduced and its output voltage will remain stable at 4.7V. In a switch mode power supply, the 1N5267B-TR can be used to regulate the output voltage by providing a stable voltage regardless of fluctuations in the input. In a general power supply circuit, the diode can be used to avoid overvoltage and undervoltage conditions.In conclusion, the 1N5267B-TR is a three-terminal, low-current Zener diode that is often used in switch mode power supplies, general power supply circuits, and other applications where tight voltage regulation is important. Its design and structure allow it to maintain a very low reverse leakage current and a very tight breakdown voltage. The 1N5267B-TR operates on the principle of a Zener diode, meaning that it operates in a reverse bias configuration and provides a stable output voltage that is determined by its breakdown voltage.
