GDZ3V0B-G3-18

Diodes - Zener - Single

The GDZ3V0B-G3-18 is a single Zener diode, which is a semiconductor device that enables the flow of current in one direction but not the other. It is used commonly in the manufacture of integrated circuits, such as those used in smartphones and personal computers.

Application Field

The GDZ3V0B-G3-18 is widely used in circuits with voltage regulator functions due to its high stability, which includes its ability to regulate voltage over a wide range of conditions and temperatures. Widely used applications include power circuits, switching power supplies, and in alternative energy.

Working Principle

The GDZ3V0B-G3-18 is based on the Zener Effect, which is the miniaturization of the Gunn effect that is found in larger current devices such as transistors and thyristors. When a high voltage is applied to the end of a reverse-biased PN junction, electrons in the crystal lattice become excited and generate energetic photons. These photons then relieve their energy in the form of heat, which causes electrons to recombine resulting in current from electron - hole recombination.

The current decreases with increasing voltage, reaches a minimum and then increases with increasing voltage when the breakdown voltage is reached. This is due to the fact that the GDZ3V0B-G3-18 is a Zener diode, which has a heavily doped region close to the junction which allows for a current to flow in the reverse direction when the breakdown occurs. The GDZ3V0B-G3-18 can also be used as clamping diodes to provide protection against electrical surges in AC power circuits.

In summary, the GDZ3V0B-G3-18 is a single Zener diode that is widely used for regulating voltage and providing protection against electrical surges in AC power circuits. It uses a reverse-biased PN junction and heavily doped region close to the junction, to generate a current when the breakdown voltage is reached.
