BZX85C8V2 Application field and Working Principle

The BZX85C8V2 is one of the single zener diodes, a type of diode which is widely used for its distinct properties, enabling it to be used in many applications. It is known for its precision zener voltage and low noise characteristics, making it a popular choice for voltage references for all sorts of analog circuits. This article looks at some of the key features of the BZX85C8V2, including its application field and working principle.

What is a Zener Diode?

A Zener diode, also known as a breakdown diode, is a diode that allows current to flow in reverse, or ‘reverse bias’, when the voltage reaches a certain ‘breakdown voltage’. This makes them a particularly useful component for voltage regulation applications. Once the voltage reaches the breakdown voltage, current flows in the opposite direction, dropping the voltage and ensuring the voltage remains steady.

Features of the BZX85C8V2

The BZX85C8V2 is a single zener diode with a breakdown voltage of 8V. Along with a low noise performance, it also offers good stability, with a maximum reverse voltage of 8V and an absolute maximum voltage rating of 10V.

In terms of power consumption, the BZX85C8V2 has a low power rating thanks to its small size. Despite an absolute watt rating of 1W, its size in combination with the low rated current of just 10mA make it suitable for low-profile voltage regulation applications.

Application Field of the BZX85C8V2

Due to its wide breakdown voltage range and low power consumption, the BZX85C8V2 is suitable for a number of applications. It is most commonly used in portable electronics, such as mobile phones and laptops, as a voltage regulator to ensure a steady operating voltage. It is also used in audio equipment to help control the voltage of analog signals, and in industrial control systems to help maintain power supply stability.

Working Principle of the BZX85C8V2

The BZX85C8V2 works by allowing current to flow in reverse when the voltage reaches its breakdown voltage. This is known as the Zener effect, and it is this effect which enables it to be used as a voltage regulator. Once the voltage reaches its breakdown voltage, the current flow in reverse causes the voltage to drop, setting the voltage at its regulated level. This regulated voltage is maintained even with fluctuations in the main power supply, thereby preserving the safety of the device.

Conclusion

The BZX85C8V2 is an incredibly useful single zener diode for many applications. Its low noise performance and low power consumption make it suitable for a number of different uses, such as in portable electronics and audio equipment. It is also highly reliable, with its steady regulated voltage ensuring the safety of the device. The BZX85C8V2 is, therefore, a great choice for anyone looking for an effective voltage regulator for their device.
