Diodes - Zener - Single: 3EZ62D2E3/TR12 application field and working principle

A Zener diode is a type of semiconductor diode that enables current to flow in either direction when connected in series with a load. It is important to note that a Zener diode can only handle a limited amount of power. This makes it suitable for applications where voltage or current regulation needs to take place to protect sensitive components. Examples of such applications include power supply regulation, voltage reference, overvoltage protection, etc.

The 3EZ62D2E3/TR12 Zener diode is a single device designed for low-power, low-voltage, low-leakage applications. It offers nominal Zener voltage of 4.7V with a maximum Zener voltage of 5.17V. It has a maximum power dissipation rating of 500mW and a maximum reverse current (IR) rating of 100mA. Other features of the 3EZ62D2E3/TR12 include stability, low noise, and excellent temperature stability. It is available in a small package that offers easy mounting.

The general working principle of a Zener diode is that when a positive voltage is applied, the diode behaves like a normal diode and only allows current to flow in one direction, from anode to cathode, and blocks the current in the opposite direction. However, when the voltage reaches a specific threshold known as the breakdown voltage, a strong reverse current will suddenly appear, which typically remains at a steady and fixed value regardless of the applied voltage.

In order to understand the 3EZ62D2E3/TR12 application field, it is important to understand the basic operation of the Zener diode. When a normal diode is reversed biased, the potential of the cathode should be higher than the potential of the anode. As the reverse-biased voltage is increased, the current initially rises until it reaches a value known as the knee voltage, which is the breakdown voltage of the diode. Above this voltage, the diode enters what is known as a "zener region of operation" where the current remains constant and there is no rise in voltage beyond the zener voltage.

The 3EZ62D2E3/TR12 Zener diode is suitable for applications that require low-voltage and low-leakage regulation. It is designed to provide stability and excellent temperature stability, and can be used for low-power and low-leakage current regulation such as voltage reference and overvoltage protection. In these applications, the diode functions by clamping the voltage to the Zener voltage, thus protecting sensitive components from overvoltage.

In conclusion, the 3EZ62D2E3/TR12 Zener diode is a single device designed for low-power, low-voltage, low-leakage applications. It offers nominal Zener voltage of 4.7V with a maximum Zener voltage of 5.17V, and has a maximum power dissipation rating of 500mW and a maximum reverse current rating of 100mA. It is suitable for low-voltage and low-leakage current regulation such as voltage reference and overvoltage protection.
