Diodes - Zener - Single: 2EZ4.7D5E3/TR8 application field and working principle

Introduction

2EZ4.7D5E3/TR8 is a single Zener diode produced by the company. This component utilizes the avalanche effect to allow for medium level current conduction and works properly under a wide range of temperatures. By understanding the application field and working principle of this device, users can get more out of this component and applying it to their projects with more confidence.

Application field

2EZ4.7D5E3/TR8 diode can be mainly used in the following areas:

• Power protection in automotive industry. It can be used to protect the system’s sensitive components against voltage spikes.
• LED displays and lightings. The circuit needs voltage regulation and the Zener diode provides a much better and more precise regulation than transistors and resistors.
• Voltage and current stabilizing. It can help to stabilize the voltage and current in the circuit, ensuring proper operation of the components depending on that particular source.
• Power supply stabilization. This diode can help to keep a constant power supply and protect other components from interference by unexpected current.

Working principle

2EZ4.7D5E3/TR8 diode works in a way similar to an ordinary diode but with a small twist. It has a built-in Zener voltage, usually between 2 and 50 volts, depending on the type you choose. The Zener voltage is an optimal voltage for taking advantage of the Zener effect.

The Zener effect occurs when the voltage of the Zener diode bridges the forward voltage, allowing the current to flow through it. However, the current cannot surpass the reverse breakdown current that is lower than the maximum rated current. At the same time, the Zener diode increases its resistanve with the increase of the applied voltage in order to maintain the current.

The Zener effect is especially useful when using transistors in switching voltage regulators, allowing the current to stay at a constant and stable rate even when the input voltage is fluctuating. This is because the Zener diode can stay at the same level regardless of the fluctuations.

Conclusion

Among all single Zener diodes, 2EZ4.7D5E3/TR8 has a wide range of uses in both power protection systems and LED displays. This diode is able to protect devices from power fluctuations while maintaining a steady degree of resistance, thanks to its Zener effect. In this way, users can confidently deploy this diode in their circuits and be assured of a stable power supply.
