DZ4J068K0R Diode Array

DZ4J068K0R is a diode array consisting of two 28V Zener diodes made available by Texas Instruments to offer excellent static and dynamic characteristics while providing two voltage channel options. This diode array has two separate channels that offer 28 volts of protection and 0.1 microamp reverse leakage current. It is designed for use in various applications such as power line protection, or surge protection, and is rated for a breakdown voltage of 28 volts and a maximum power dissipation of up to 1.5W. This device is offered as an 8-lead UL4N package for improved thermal and electrical performance.

DZ4J068K0R Application Field

DZ4J068K0R is applicable to various circuit protection needs, such as powering electronics, digital buses, and other demanding applications. It is suitable for protecting digital systems from overvoltages due to ESD, electrostatic discharge, or inductive transients. Other possible applications include general power line protection, system voltage transients, or surge protection. This device can also be used in automotive, general-purpose protection, and audio circuits.

DZ4J068K0R Working Principle

Using a two-channel structure, the DZ4J068K0R diode array is capable of controlling and maintaining two lines of power. In its simplest form, when a DC voltage of 28 volts is applied to the closed circuit, it will cause current to flow across the Zener diodes. The current will then continue to flow at the voltage set by the Zener breakdown voltage until the voltage increases or decreases. The voltage maintained at its set level is known as the regulation voltage or clamp voltage.In the event of transients or overvoltage, the DZ4J068K0R diode array will limit the voltage at its breakdown voltage. This serves to clamp or shunt the voltage down and protect the power circuit from the overvoltage. The DZ4J068K0R diode array also provides low reverse leakage current, improving energy efficiency.

Conclusion

The DZ4J068K0R diode array is suitable for many applications requiring two channel power protection, such as powering electronics, digital buses, and other demanding applications. It is able to control and maintain two lines of power while clamping or shunting the voltage down to its breakdown voltage in the event of an overvoltage. Its low reverse leakage current also adds to its energy efficiency, making it a desirable choice for many electronic and power circuits.
