Diodes - Zener - Single is a category for diodes that have a distinct characteristic referred to as the Zener effect, resulting in breakdown of the p-n junction. A 1N4475 TR is a type of such diode, specifically designed to perform a voltage-regulable function. The 1N4475 TR application field as well as its working principle will be discussed in this article.

Application Field

The 1N4475 TR is a low-power Zenner diode, usually used in industrial equipment. It can manage both sharp and slow overloads and is generally used as a voltage regulator. It is low power, yet can handle a lot of energy with tolerances of up to 56V. The 1N4475 TR is particularly well-suited for applications such as converters, motor controls and solid-state relays in white goods. It can also be used for telecom and IT systems.

The 1N4475 TR can be used for linear power supplies and battery protections in automotive applications, for DC-DC converters for cell phone charging boards, as well as for stepped-up converters and DC-DC converters. It can also be used in IDMs and embedded systems as a voltage supervisor and can be used in any situation that needs to regulate voltages.

Working Principle

As with all Zener diodes, the 1N4475 TR is designed to regulate voltage by creating a reverse breakdown of the p-n junction. The voltage at which this breakdown occurs is the Zener voltage and is determined by the composition of the semiconductor material. Once the breakdown occurs, an avalanche current that is proportional to the reverse bias voltage flows. This Zener diode effect regulates voltage and keeps it constant, ensuring that connected components receive only the desired amount.

The working principle of the 1N4475 TR includes both the Zener effect and the reverse breakdown. The Zener effect begins with the biasing of the p-n junction by reversing the current direction. This reverse bias applies a voltage across the p-n junction, causing it to breakdown. The breakdown causes electrons to be liberated at the p-n junction, creating an avalanche current. This avalanche current is what makes the 1N4475 TR unique. As it passes through the diode, it causes the voltage across the diode to remain constant, even as current fluctuates.

The 1N4475 TR is a particularly reliable diode due to its high peak reverse voltage and low leakage current. This ensures that the device can withstand high voltages and maintain a low current, making it suitable for many industrial and automotive applications. The device also has a small size, allowing it to be implemented in a number of confined spaces.

Conclusion

The 1N4475 TR is a type of Zener diode designed to perform a voltage regulable function, making it suitable for many industrial, automotive and telecom applications. Its working principle consists of both the Zener effect and reverse breakdown, which create a constant voltage across the diode, no matter the current fluctuations. The 1N4475 TR is unique due to its high peak current, low leakage, and small size, ensuring reliable protection from voltage fluctuations.
