Application Fields

The GDZ2V7B-G3-18 is able to provide current limiting, voltage regulation, and circuit protection from damaging over currents. It is capable of being used in audio amplifiers for oscilloscopes, battery protection circuits, communication circuits, electric instruments, medical and industrial equipment, and power supply circuits. It is also frequently used in high-voltage motor control modules, lightning surge protection applications, float charging and other electronic safety applications.

Working Principle

The GDZ2V7B-G3-18 consists of a P-type and N-type semiconductor that are combined to create two separate PN junctions. The Zener diode is a two terminal device that relies on the movement of electrons between these two junctions in order to limit the amount of current and voltage that can flow through the diode. When the voltage passes a certain level, electrons are able to pass through the junction, which reduces the voltage and diverts current away from the circuit, thus providing protection.

Due to the nature of the device, the GDZ2V7B-G3-18 is able to sense current, and will monitor the current before and after the Zener diode to determine if it should reduce the voltage or divert the current. This allows it to, for example, differentiate between a direct electrical short and a current surge, which can be particularly useful in many safety applications.

Conclusion

The GDZ2V7B-G3-18 is a single Zener diode that is designed for multiple safety applications in order to protect circuits and prevent damage caused by reverse voltages and electrical shorts. By monitoring and reducing the current and voltage of the diode, it is able to provide maximum protection in order to keep circuits working as intended. The device operates on the principle of two separate PN junctions in order to monitor and redirect currents to prevent damage in multiple applications.
