NZ9F9V1T5G Discrete Semiconductor Products

Diodes - Zener - Single

The NZ9F9V1T5G diode has a variety of applications in the electrical and electronic engineering field.

Application Field:

One application is as a voltage regulator. The NZ9F9V1T5G is a zener diode, which is designed to break down when the voltage across it reaches a pre-defined value. It is this characteristics that makes the NZ9F9V1T5G useful as a voltage regulator to ensure a consistent output voltage. Another application is as a voltage protector. The high resistance of the NZ9F9V1T5G means that it can help protect other components in an electrical and electronic circuit from obtaining too much voltage.

Working Principle:

When the forward voltage of a diode exceeds the breakdown voltage, or ‘zener voltage’ of the diode, it will begin to break down in a process known as Zener breakdown. The NZ9F9V1T5G diode has a single zener voltage and as such, is referred to as a ‘single zener diode’. The zener voltage is the voltage at which the zener breakdown begins and it is this that makes the NZ9F9V1T5G useful in applications such as voltage protection and voltage regulation.

The Zener breakdown in the NZ9F9V1T5G is strictly controlled and occurs in the form of what is known as a ‘Reverse Avalanche Breakdown’. This process occurs because the diode has a very high reverse biased electric field that is easily sustained. This electric field increases rapidly as the voltage is increased, eventually reaching a level whereby electrons are accelerated in the junction, leading to the beginning of a ‘lattice’, which allows the current to increase rapidly. The rate at which this current increases is limited by the physical structure of the NZ9F9V1T5G, but it can increase rapidly enough to keep the voltage at a very precise and consistent level.

The NZ9F9V1T5G diode is an excellent choice for a number of electrical and electronic engineering applications due to its precise and consistent breakdown voltage and low cost. It can be used for voltage protection and voltage regulation in a variety of circuits to ensure that the components are not damaged by overstress or inconsistent voltages.
