Diodes - Zener - Single:

3EZ4.7D10/TR8 is a single zener diode which is primarily used for voltage regulation purposes. This specific diode’s breakdown voltage is 4.7V, which makes it suitable for applications that require a regulated 5V output.

The device is housed in a SOT-23 (Small Outline Transistor or Surface Mount Transistors) package, and provides thermal stability. This package is an industry-standard and is designed for automatic placement and soldering in modern assembly equipment.

Application Field:

Given its wide operating range and 4.7V breakdown voltage, 3EZ4.7D10/TR8 is commonly used in digital and analog circuits that require a 5V reference voltage. It can be used as an input voltage regulator for high-speed data sampling circuits, as well as a voltage reference for general-purpose circuits.

3EZ4.7D10/TR8 is especially useful for microcontroller (MCU) applications. It is often used for microcontroller reset circuits, low-power motor control, and low-power light driver applications. This diode is also a popular choice for 3V or 5V power supplies found in industrial applications, including automotive, outdoor uses, home appliances, and even toys.

Working Principle:

The working principle of 3EZ4.7D10/TR8 is quite simple and similar to all other zener diodes. In its simplest form, a zener diode is composed of two semiconductor junctions, with the reverse breakdown voltage determined by the impurities (a process called “doping”) added to the semiconductor material. When the current surpasses a certain threshold, the reverse junction begins to conduct, allowing a fixed voltage to be dropped across the zener diode.

The breakdown voltage of a zener diode is determined by its doping level, which is typically between 2V and 15V. As a result, the amount of current that can be passed through a zener diode depends on its breakdown voltage. 3EZ4.7D10/TR8 has a 4.7V breakdown voltage, which allows a current of up to 10mA through the device.

3EZ4.7D10/TR8 is also designed to have a good thermal stability – meaning that the breakdown voltage is not significantly affected by temperature change. This feature makes 3EZ4.7D10/TR8 suitable for long-term and high-reliability applications that require an exact and stable voltage level. As a result, it is widely used for microcontroller-based systems that need to be constantly operating at the same voltage level.

Conclusion:

3EZ4.7D10/TR8 is a single zener diode used primarily for voltage regulation in various applications. Its 4.7V breakdown voltage and thermal stability make it well-suited for digital and analog circuits, as well as microcontroller circuits. Moreover, its SOT-23 surface mount package ensures easy installation in modern assembly equipment. All these features make 3EZ4.7D10/TR8 an ideal choice for long-term and high-reliability applications that require a constant voltage level.
