Diodes - Zener - Single: DDZ6V8C-7 Application Field and Working Principle

A 10 V 5 mA Zener Diode with precision tolerances, such as DDZ6V8C-7, is commonly used in some applications. This type of diode is a form of voltage regulation that is used in all types of electronic circuits, such as signal processing, remote control, measurement and instrumentation and audio circuits.

Introduction

A diode is a 2 terminal semiconductor device with a pn junction, in which conduction of electric current can take place in one direction only. It operates as either an insulator or a conductor. A Zener diode is a device made of special semiconductor materials, which conducts electric current even when the voltage is reversed. The most common and useful feature of this diode is its property of having a constant voltage across it, known as the breakdown voltage or Zener voltage, Vz. This property of having a constant voltage, makes it ideal for use in voltage regulation circuits.

DDZ6V8C-7

The DDZ6V8C-7 is a 10V 5mA Zener Diode with precision tolerances. It has a maximum power dissipation of 500mW, a maximum reverse leakage of 8uA and a forward voltage of a maximum of 0.45V. Its high voltage tolerance means it is ideal in many applications such as stabilizing voltage regulated power supplies and for protecting sensitive components like transistors and opto-electronic devices. The pinout for the diode is marked on the diode with an exploded view. It has an anode, which is the positive lead, and a cathode, which is the negative lead. In order for the diode to operate correctly and be correctly applied, the anode must be at a higher voltage than the cathode.

Application Fields

• Signal Processing: The most common application for the DDZ6V8C-7 diode is in voltage regulation circuits, such as signal-processing circuits where shortening of signals or thresholding of signals is required.• Remote Control: The DDZ6V8C-7 is also widely used in remote-control circuits, making them reliable and stable. • Measurement and Instrumentation: This diode is suitable for use in audio circuits and instruments as well because of its accuracies in tolerances and its high voltage tolerance properties. • Audio Circuits: The DDZ6V8C-7 is also used in audio circuits due to its proven stability and reliability when passing of audio signals are concerned.

Working Principle

When a Zener diode is forward biased and the applied voltage reaches its “breakdown” voltage, Vz, a very large current will flow through the diode, known as the Zener current, Iz. When the applied voltage is at the Zener breakdown voltage, Vz, the diode will pass significant current, thereby maintaining a constant voltage, Vz. The Zener current is limited by a series resistor, Rz, connected in series with the diode. The Zener diode operating in this manner is known as Zener voltage regulator. This type of voltage regulator is commonly used to monitor and maintain a constant voltage such as in audio circuits, remote- control circuits, or measurement and instrumentation circuits.

Conclusion

The DDZ6V8C-7 is a 10V 5mA Zener Diode with precision tolerances. It is used in a variety of applications, such as signal-processing, remote-control, measurement and instrumentation, and audio circuits. Its primary working principle is by maintaining a constant voltage across the diode by having a large current flow through the diode when the applied voltage reaches its breakdown voltage, Vz. It is this property of Zener diodes, which make them particularly suitable for voltage-regulation applications.
