GDZ6V2B-HG3-08

GDZ6V2B-HG3-08 application field and working principle

Diodes are one of the most important elements used in the industry today. Zener diodes, a subset of diodes, are particularly essential in rectifier, voltage regulator and other power related applications for their ability to maintain strict voltage regulation in the circuit. GDZ6V2B-HG3-08 is a single Zener diode manufactured by Diodes Inc., with its main application in mobile broadband routers to protect sensitive antennas from the adverse overvoltage effect.

GDZ6V2B-HG3-08 is a semiconductor device made of silicon material and exhibits the same characteristics of any other Zener diodes - they conduct current in both directions and regulate a specific voltage level. It has a peak forward voltage of 6 V and a maximum reverse current of 300 mA. It has superior reverse standoff characteristic, with a Vz tolerance of ±4%.

The working principle of GDZ6V2B-HG3-08 is quite simple. It consists of a junction between p-type and n-type semiconductors. When a reverse bias is applied to this junction, the diode will break down at a certain level called the Zener voltage or breakdown voltage. This voltage level is always above 5V but within specific tolerance. Once the reverse voltage is within the breakdown voltage level of the diode, a current will flow in the reverse direction. This current is called the Zener current, and at a constant Zener voltage, the Zener current will flow in a stable manner.

Due to its characteristics, GDZ6V2B-HG3-08 is mainly used in mobile broadband routers to protect sensitive antennas from damage due to high over voltages. When there is an over voltage that is higher than the Zener diode\'s breakdown voltage setting, instead of travelling through the antenna, the voltage is safely discharged through the diode, protecting the antenna from damage. 

In conclusion, GDZ6V2B-HG3-08 is a single Zener diode from Diodes Inc., mainly used in mobile broadband routers to protect sensitive antennas from damage due to overvoltages. It conducts currents in both directions and regulates a specific voltage level when a reverse bias is applied to its junction. This voltage is determined by its Vz tolerance and its peak forward voltage, providing superior protection for the circuit.
