1N5381BE3/TR13

Introduction

The 1N5381BE3/TR13 is a Single Zener Diode from the popular 1N5381 Series by ON Semiconductor. This series of Zener Diodes are reliable, easy-to-use, and according to the manufacturer, offer high performance and low power consumption. This particular diode has a wide range of operating conditions, making it highly versatile. In this article, the application field and working principle of the 1N5381BE3/TR13 will be discussed.

Application Field

This type of Zener Diode can be used in a broad range of applications ranging from low voltage to high voltage. Its common uses include general purpose voltage regulation, noise filters, transient voltage suppression, and voltage references. The 1N5381BE3/TR13 can be used in both AC and DC circuits, as well as in automotive circuits. Its high tolerance to reverse voltage makes it especially useful in reverse voltage protection circuits. It is also an ideal choice for current limiting and clamping applications due its high breakdown voltage.

Working Principle

The working principle behind a Zener Diode is quite simple: when a certain threshold voltage is applied to the diode, it breaks down and allows current to flow. This effect is known as Zener breakdown. Essentially, the Zener Diode is used as a voltage regulating device, as it has a maximum voltage rating. The Zener Diode will regulate the current passed through it to the rated voltage, regardless of the amount of voltage applied to it.

When a reverse voltage is applied to the diode, the diode does not allow any current to flow. This is because the diode is reverse biased, and the depletion layer acts as an insulator, preventing any current from passing through the diode. The same is true when forward bias is applied to the diode; up until the Zener voltage is reached, no current will flow through the diode. However, once the Zener voltage is reached, the diode will break down and allow current to flow.

Conclusion

The 1N5381BE3/TR13 is a single Zener Diode from the ON Semiconductor 1N5381 Series. This diode is highly versatile and can be used in a wide range of applications, including general purpose voltage regulation, noise filters, transient voltage suppression, voltage references, and current limiting. The working principle of the Zener Diode is quite simple; when reverse bias is applied, the diode will not allow any current to flow, and when forward bias is applied, no current will flow until the Zener voltage is reached. Once this is reached, the Zener Diode will allow current to flow.
