Diodes - Zener - Single

A Zener diode, called a voltage-regulated diode, functions like an ordinary diode, but it also can provide a specific reference voltage for other components. Specifically, a PZU6.8B,115 Zener diode is a PN junction diode that is designed to break down at a specifically defined voltage, providing a reference voltage for other components. The PZU6.8B,115 Zener diode is a single diode, meaning that it only has two connections, an anode and a cathode.

Working Principle

The working principle of a Zener diode is based on the principle of breakdown. In a conventional diode, when a voltage is applied across it, a current flows in only one direction 0 - the forward direction. This is known as forward bias. When the applied voltage reaches a certain threshold known as the peak inverse voltage or PIV, the diode will break down and a current will flow in the opposite direction - this is known as reverse bias. The reverse bias current is not constant though; it varies greatly with the applied voltage. In a Zener diode, this reverse breakdown voltage is kept very constant - hence the reason why it is called a voltage regulated diode.

Application Field

The main application of a PZU6.8B,115 Zener diode is for the purpose of voltage regulation. It enables a constant and consistent reference voltage to be provided to other components, so that they can be precisely tuned. This consistent and stable reference voltage makes the PZU6.8B,115 a suitable device for a wide range of applications. The PZU6.8B,115 can also be used as a voltage limiter, as the Zener diode can be used to limit the voltage of a circuit or device to a specific threshold. This is extremely helpful in protecting sensitive electronics and components from dangerous and damaging voltages. In addition, Zener diodes can be used as a voltage regulator or surge protector, as they can be used to equalize the voltage levels in a circuit, so that the levels do not exceed a certain threshold. This prevents the circuit from becoming overloaded, due to large spikes in voltage, resulting in malfunction or even destruction of components.

Advantages of a PZU6.8B,115 Zener Diode

• The PZU6.8B,115 is an efficient voltage-regulator device, as it can provide a reference voltage to other components. This reference voltage is extremely reliable, because it is against a relatively constant breakdown voltage.
• It is also a cost-effective voltage regulator, as it is much cheaper than other voltage-regulation methods.
• It is also very small in size and can be easily integrated into circuits.
• It is an extremely reliable voltage-limiter device, as it can effectively keep voltages within an acceptable level.
• It does not require a large amount of power to function, so it is suitable for low-power circuits.

Disadvantages of a PZU6.8B,115 Zener Diode

• The reverse current of a Zener diode is not consistent; it depends heavily on the amount of current flowing through it. This makes it difficult to accurately predict the precise voltage that the diode will break down at.
• The breakdown voltage of the diode is still affected by changes in temperature and humidity, so the PZU6.8B,115\'s reference voltage can fluctuate fairly easily.
• The PZU6.8B,115 is not suitable for high-power applications, as it cannot handle high levels of current and power.

In conclusion, the PZU6.8B,115 Zener diode is an extremely versatile device, due to its ability to provide a consistent reference voltage. This feature makes it suitable for a wide range of applications, from voltage regulation to voltage limiting. Despite its many advantages, the PZU6.8B,115 still has some disadvantages, such as its inability to accurately predict its breakdown voltage, as well as its susceptibility to temperature and humidity changes.
