Diodes - Zener - Single

The 1N4625UR diode is a Zener diode, a form of diode which, like all diodes, is an electrical semiconductor device that is used to either direct current in one direction, or block it. The unique properties of the Zener diode enable it to enable it to create the same uniform voltage regulation in either direction.

Application Field

The 1N4625UR diode is often used to provide stable voltage in applications where high reliability and low power drain are required. It is also capable of operating in a wide range of temperatures, from -65 to 105 degrees Celsius. Furthermore, its small size enables it to be contained within a wide variety of circuits without requiring external power.

One of the primary applications for the 1N4625UR diode is the protection of electronic components from voltage spikes. By clamping the voltage, the diode ultimately helps to prevent failure and damage to otherwise fragile components. Additionally, 1N4625UR diodes can be used as an electrical switch in audio systems in order to prevent small impedances that would otherwise cause problems.

Working Principle

The primary purpose of the 1N4625UR is to regulate voltage by operating within the Zener breakdown region. When a certain reverse bias voltage is applied to the diode, conduction of electric current from its anode to its cathode will occur. This can be visualized as the Zener diode entering the Zener breakdown region, in which the electric field strength within the diode is strong enough to break the electric field that is maintaining the non-conductive nature of the p-n junction. When this happens, electric current is able to flow freely within the diode, thus achieving the desired voltage regulation.

The amount of power that these diodes can handle depends on their maximum power dissipation rating, and should be taken into consideration when selecting the right diode for a specific application. Furthermore, the actual breakdown voltage can be affected by the fluctuations in the ambient temperature, therefore it must be taken into account when specifying the required power level.

Conclusion

1N4625UR diodes are ideal for applications where high reliability and low power requirements are present. Their ability to protect components from voltage spikes and provide uniform voltage regulation across a wide range of temperatures makes them a popular choice. Additionally, their small size ensures that a wide variety of circuits can be contained without requiring external power.
