A Zener diode, sometimes referred to as a Zener regulator, is a type of diode that is primarily used to regulate voltage in a circuit. Zener diodes have a unique property in that they are able to operate in both directions by allowing electricity to flow through them either in a forward direction or in a reverse direction. In general, a Zener diode can be used to regulate the voltage in a circuit, to protect a circuit from excessive voltage, or to provide a stable reference voltage.

The GDZ20B-HG3-08 is a single Zener diode that has a voltage range of 8 to 20 volts. The GDZ20B-HG3-08 is designed for use in a wide range of electronic applications, such as voltage regulators, voltage protection circuits, and other circuits that require a constant voltage. The GDZ20B-HG3-08 is also designed with a low reverse leakage current and a low power dissipation, making it suitable for use in low voltage, low power applications.

In order to understand the application field and working principle of the GDZ20B-HG3-08, it is first important to understand how a Zener diode works. A Zener diode operates by allowing electric current to flow through it in either direction. In forward bias mode, current flows from the anode to the cathode; while in reverse bias mode, current flows in the opposite direction. The voltage at which a Zener diode begins to conduct in reverse bias is known as the Zener voltage, or avalanche voltage. The Zener voltage of the GDZ20B-HG3-08 is 8 to 20 volts.

In applications such as voltage regulation and voltage protection, the GDZ20B-HG3-08 is used to prevent excessive voltage from damaging a circuit. When the voltage in a circuit exceeds the Zener voltage, the GDZ20B-HG3-08 will begin to conduct in reverse bias, allowing current to flow through the diode in the opposite direction and limiting the voltage to the Zener voltage. This ensures that the voltage in the circuit does not exceed the Zener voltage and protects the circuit from damage.

The GDZ20B-HG3-08 can also be used in circuits that require a stable reference voltage. When the GDZ20B-HG3-08 is in forward bias, the voltage across the diode will remain constant, regardless of the circuit’s load. This makes it ideal for use as a reference voltage in circuits such as voltage dividers. In these applications, the GDZ20B-HG3-08 is connected in series with a resistor, which creates a voltage divider circuit that provides a stable and accurately-measured reference voltage.

In summary, the GDZ20B-HG3-08 is a single Zener diode that is designed for a voltage range of 8 to 20 volts. It can be used for applications such as voltage regulation, voltage protection, and as a reference voltage. The GDZ20B-HG3-08 is designed with a low reverse leakage current and a low power dissipation, making it suitable for use in low voltage, low power applications.
