Introduction to BZX79-B6V8,143

BZX79-B6V8,143 is a diode in the Zener Single category. This diode is widely used to provide voltage regulation in power systems and also provides high levels of protection against overvoltage, reverse leakage current and transient surge protection. This diode is often used in ac/dc converters, high-power rectifiers, offline led lighting, power supplies and other power electronics applications.

What Is a Zener Diode?

A Zener diode is a semiconductor device that has a reversed biased p-n junction. This diode exhibits an avalanche breakdown, when the reverse voltage applied is greater than a specified ‘zener’ voltage. Zener diodes are usually used for voltage regulation duties to stabilize a voltage. When the reverse voltage exceeds the breakdown point, a large current will begin to flow across the p-n junction of the diode. This phenomenon is known as the Zener Breakdown Effect and it is this effect that makes Zener diodes so popular.

Application Field of BZX79-B6V8,143

The BZX79-B6V8,143 is a P-I-N (PIN) diode with a reverse breakdown voltage of 5.6V. As a result, this diode is particularly useful in applications where a stable and consistent reverse voltage is required. This includes power supplies, ac/dc converters, high-power rectifiers, and offline LED lighting systems. In all of these applications, the diode is used to control the forward voltage and current, while providing protection against transient surges, overvoltage, and reverse leakage.

Working Principle of BZX79-B6V8,143

The working principle of a Zener diode is based on the P-I-N junction of the device. When a reverse voltage is applied to the diode, a large electric field will be created. This electric field will build up until it reaches a point where it is strong enough to cause a breakdown of the junction between the P and N layers. At this point, a large current will begin to flow across the junction and this is known as the Zener breakdown effect.The Zener breakdown effect is the basis of the regulating function of the BZX79-B6V8,143 diode. When a reverse voltage is applied, the diode will regulate the voltage and current in order to meet the specified breakdown voltage. This effectively provides protection against overvoltage and other unwanted effects.

Conclusion

In summary, the BZX79-B6V8,143 is a Zener Single diode that is widely used in power systems where a stable, consistent reverse voltage is required. This diode utilizes the Zener breakdown effect to regulate the voltage and current, providing protection against overvoltage, reversals, and other unwanted effects. This diode is commonly used in ac/dc converters, high-power rectifiers, and offline led lighting systems.
