Diodes are widely used in electronics and electrical engineering, providing a variety of functions such as rectification, regulation, protection, communications, and more. Zener diodes are commonly used in voltage regulation, especially in power supplies, allowing precise control of voltage levels. Single zener diodes, such as 2EZ150D2E3/TR12, are widely used in a variety of applications. This article will discuss the application fields and working principle of 2EZ150D2E3/TR12.

Application Field

2EZ150D2E3/TR12 Zener diode is a low-power, 6.2-volt zener diode suitable for general-purpose voltage regulation, anywhere from 4.3V to 6.2V. Due to its low power (0.2W) and low forward voltage, it is commonly used in audio and RF applications, such as:

• RF mixer stabilization
• Bias circuits for mobile phones
• High-frequency amplifiers
• RF filter stabilization
• Passive-gas pressure regulators
• Voltage regulator for low wattage LED lights

Working Principle

The 2EZ150D2E3/TR12 Zener diode operates using the Avalanche effect, which allows the diode to regulate the voltage by conducting with very low amounts of current, below the breakdown voltage called knee voltage. The diode is designed so that the current passing through it is nonlinear and increases exponentially as the voltage increases.

To understand how the diode works, it\'s necessary to understand the characteristics of a semiconductor junction. When a reverse bias is applied, electrons and holes will be repelled from each other due to the applied voltage, setting up a region of low electric field. The depletion region is formed when the electrons and holes have completely separated so that the electric field between them is zero.

When the reverse bias is increased further, electrons and holes in the region closest to the junction will arrive at a point where the electric field is strong enough for them to start to cross the junction. This process is known as the Zener breakdown, where electrons from the N-type material cross into the P-type material and holes from the P-type material cross into the N-type material. This process produces charge carriers, which reduces the depletion region and increases current. The idea is that the current through the diode increases exponentially until the junction potential is equal to the applied voltage.

The 2EZ150D2E3/TR12 Zener diode works by creating a stable conductive route once a certain reverse voltage has been applied across its anode and cathode. The diode then regulates the voltage by conducting with very low amounts of current, below the breakdown voltage called knee voltage. The knee voltage is the point at which the diode starts conducting, a feature which makes it suitable for voltage regulation.

When using 2EZ150D2E3/TR12 in practical applications, it is advisable to take into consideration the thermal management as the diode can dissipate heat at high temperatures. Also, it is necessary to take into consideration the reverse current as it can increase up to several milliamps in certain conditions. It is recommended to use the diode in low current applications with proper protection circuits, such as reverse polarity protection and series current-limiting resistors.

Conclusion

The 2EZ150D2E3/TR12 Zener diode is a low-power, 6.2-volt zener diode that is suitable for general-purpose voltage regulation, anywhere from 4.3V to 6.2V. It is commonly used in audio and RF applications as it has a low forward voltage and works using the avalanche effect. When using 2EZ150D2E3/TR12 it is recommended to take into account the heat dissipation and reverse current. It is also recommended to provide proper protection circuits for even more reliable operation.
