Diodes are a type of semiconductor device with two p-n junctions that can be used to conduct or block current. The Zener diode is a type of special diode that is designed to operate in reverse bias condition. A single Zener diode is used in a TDZVTR20 application and works based on the Zener breakdown principle.

When the voltage applied to single Zener diode is increased, a depletion region forms at the junction and therefore an electric field is created. This electric field further increases when the applied voltage keeps rising and it eventually reaches a critical value, known as the Zener breakdown voltage (VZ). This causes a surge of current to flow through the diode and the diode starts to conduct in the reverse direction. The amount of current flowing through the diode is much greater than the normal current increases in the forward direction of the junction.

The TDZVTR20 application field involves using single Zener diodes for voltage regulation. They are used to provide a constant reference voltage at a certain load current. The Zener diode has a relatively low breakdown voltage, which is predetermined when it is manufactured. When the voltage applied to the diode is below the predetermined value, the diode will block the current flow and it will not conduct. However, when the voltage is above the Zener breakdown voltage of the diode, it will allow a reverse current to flow and the voltage across the diode will become constant. Thus, the Zener diode can be used as a voltage regulator.

The single Zener diode in the TDZVTR20 application works as a voltage regulator by responding quickly to the changes in voltage. The changes in voltage make the diode to move its reverse current bias point up or down and its output voltage remains constant. This happens because when the voltage increases, the diode starts to conduct and when the voltage decreases, the diode blocks the current. This helps in providing stability to the circuit and prevents any kind of voltage fluctuations.

In summary, the TDZVTR20 application uses a single Zener diode that works based on the Zener breakdown principle. When the voltage applied to the diode is increased, the electric field around the junction increases to a critical value. This causes a surge of current to flow through the diode and the diode starts to conduct in the reverse direction. The Zener diode is used as a voltage regulator and it helps in providing stability to the circuit, preventing any kind of voltage fluctuations.
