The GDZ18B-HG3-08 is a single Zener diode ideal for use in voltage regulation and supervision applications. This diode features an avalanche breakdown voltage that is temperature independent, making it really suitable for linear voltage regulation applications.

This Zener diode has a maximum power dissipation of 500mW with a reverse voltage of 5.1V. It is constructed with a planar construction made up of N+ layer and PN junction barrier layers. The N+ layer consists of lightly doped N region with the PN junction forming the diode structure.

The GDZ18B-HG3-08 Zener diode is used to maintain a constant voltage level regardless of current, enabling intimate voltage regulation or voltage clamping. It works by allowing current to flow in the forward direction, in the same way it does for a regular diode, but also permits and controls a significant amount of reverse current when the reverse voltage surpasses the nominal value.

In voltage regulation applications, the GDZ18B-HG3-08 is used to hold an output voltage to a consistent and controlled level, no matter what happens to the current. The diode is connected in a circuit configuration and it is designed to clamp the output voltage at a designated level. In this way, current flows through the diode, and the constant force is able to maintain a stable output voltage.

In voltage supervision applications, the GDZ18B-HG3-08 works in a similar way to the voltage regulation. It is used to monitor and observe the output of a power supply. This is done to ensure that the voltage is remaining consistent and that it does not exceed the maximum value. If the voltage exceeds the maximum value, the diode can be used to protect the power supply, protective circuits, and sensitive equipment.

The main feature of the GDZ18B-HG3-08 is its ability to maintain a constant output voltage in both voltage regulation and voltage supervision applications. This diode has a planar construction with a low leakage current and a very stable temperature coefficient. This makes it ideal for use in applications that require a dependable, accurate, and compact voltage regulating or monitoring device.
