Working Principle

The BZT52H-B22,115 utilizes a Zener breakdown principle. This involves a P-N junction that is reverse biased, meaning the positive and negative terminals have opposite potentials. When the voltage applied to it exceeds a certain threshold, the reverse current flowing through my go beyond the dissipation power of the diode and cause avalanche breakdown. This forms an avalanche of electrons and holes and is known as the Zener breakdown.

When this occurs, the Zener junction allows the excess current to pass through it while freeing some of the voltage across the junction. This helps to regulate the voltage in applications where fluctuations are a common occurrence and help to prevent damage to sensitive components or other parts of the system.

Conclusion

The BZT52H-B22,115 is a single Zener diode that is suited for applications such as DC/DC converters, AC/DC minimalist power supplies, electronic equipment, and telecommunications. This diode utilizes a Zener breakdown principle which involves a P-N junction that is reverse biased. When the voltage applied to it exceeds a certain threshold, Zener breakdown occurs and the junction allows the excess current to pass freely through it, while freeing some of the voltage across the junction.
