Introduction

The 3EZ150D2E3/TR8 is a single Zener diode designed for use in applications where the parameters of device packing and normal operation will be critical for the performance of the product in question. Zener diodes are used for voltage regulation and to limit overvoltage transients. This particular Zener is designed for rectifying alternating current and for providing temperature compensated reference voltages.This article will discuss the application fields and working principle of the 3EZ150D2E3/TR8.

Application Fields

The 3EZ150D2E3/TR8 is suitable for a wide range of applications, particularly those where high voltage is required to operate devices and systems. Its most common uses are rectification of alternating current (AC) and providing temperature compensated reference voltage.The diode is particularly suitable for use in electronic circuits and devices where high-voltage operation is required, such as automotive and other transportation applications, home appliance controls, and industrial equipment.In addition, the 3EZ150D2E3/TR8 is also suitable for other applications where its particular features are a value-add to the system in question, such as voltage transients, switching frequency power supplies, flyback circuits and so forth.

Working Principle

The 3EZ150D2E3/TR8 is based on the Zener diode. A Zener diode is a two-terminal diode, with an anode and a cathode, that offers low on-state voltage drop and maintains a constant voltage over a wide range of temperature and current conditions.The basic principle of operation is that Zener diodes operate in reverse-bias mode. When a Zener diode is reverse-biased, the current through the device increases as the voltage across it increases. The diode will remain reverse biased until a certain voltage, known as the Zener voltage, is reached, at which point the current will be clamped. This is the Zener breakdown. The Zener voltage is usually specified by a manufacturer. For the 3EZ150D2E3/TR8, the Zener voltage is 150 V with an allowable tolerance of +/- 5%. The device is also designed for a high power rating of 1.5 W and a low forward voltage drop between 3 V and 6 V, making it suitable for a wide range of applications.

Conclusion

The 3EZ150D2E3/TR8 is a single Zener diode designed for use in applications where high-voltage is needed and temperature compensation is required. It is suitable for applications such as rectification of alternating current, providing temperature compensated reference voltage, voltage transients, switching frequency power supplies, flyback circuits and so forth.The main principles of operation are based on the Zener diode, where the current through the device increases as the voltage across it increases, until the Zener voltage of 150 V is reached, at which point the current is clamped. The 3EZ150D2E3/TR8 has a high power rating of 1.5 W and a low forward voltage drop between 3 V and 6 V.
