GDZ2V2B-HE3-08

Diodes - Zener - Single

GDZ2V2B-HE3-08 is a zener diode at single package in SOD-122 case. It has a breakdown voltage of 2.2V. It is mainly used for EMC clamps and it works as a voltage regulator.

Application Field

GDZ2V2B-HE3-08 is mainly used for EMC clamps where a lower breakdown voltage is needed. As it has a small size, it is suitable for devices with limited space or where low power consumption is required. It can also be used for voltage protection circuits, voltage dropping or for IT systems.

Working Principle

GDZ2V2B-HE3-08 is a zener diode, which means it has two terminals giving current in one direction only. Zener diodes work on the same principle as normal power rectifiers, except that when the reverse breakdown voltage is reached they conduct the current in both directions. This type of diode is mainly used to create a stabilized voltage and an almost symmetrical waveform.

The device works in two operations. Firstly, an electric field is generated at the p-and-n junction to reduce or modify any voltage or electrical signal’s amplitude. When the electric field reaches a point above the given breakdown voltage, the diode will trigger and start to conduct current. While passing through, the current helps lower the voltage to the expected value. This action is known as Zener breakdown.

With GDZ2V2B-HE3-08, once it reaches the breakdown voltage, it will pass a certain maximum current limited by its power handling capabilities. This current will then lower the voltage to its expected value to maintain the output constant. The input and the output resistance in Zener diodes are also directly proportional to each other; the higher the current flows through, the higher the resistance will be.

Conclusion

GDZ2V2B-HE3-08 is a zener diode at single package in SOD-122 case with a breakdown voltage of 2.2V. It is mainly used for EMC clamps and it works as a voltage regulator. The device is mainly used in applications where a low breakdown voltage and a low power consumption is needed. The working principle of the device is similar to that of normal power rectifiers, except that once the reverse breakdown voltage is reached, the current is conducted in both directions. With GDZ2V2B-HE3-08, when it reaches the breakdown voltage, it will pass a certain maximum current limited by its power handling capabilities, helping to achieve its desired output.
