TVS - Diodes

The AOZ8851ADI-05 is a transient voltage suppressor (TVS) diode used for overvoltage protection and noise EMI (electromagnetic interference) filtering. TVS Diode is a device that provides protection from power transients, also known as surge protection. These devices are often referred to as clamping diodes or surge arresters.

Application Field

AOZ8851ADI-05 devices are commonly used in consumer electronics and automotive applications, such as TVs, cell phones, and automobiles. The device is suitable for use within a wide range of power levels and operating voltages, making it an ideal choice for high voltage, high upset current applications. It is also widely used in industrial control systems and data storage boards. The AOZ8851ADI-05 is used to protect sensitive components and help reduce stress on power supplies.

Working Principle

The AOZ8851ADI-05 works by providing a fast, safe bi-directional protection from damaging energy transients caused by electrical surges, electrostatic discharge (ESD), load dump, ground loops, or other sources of EMI. The device is constructed from a highly reliable semiconductor material that helps reduce stress on the power supply. When an overvoltage condition occurs, the power supply is protected and the voltage is clamped down. The performance of TVS diodes is dependent on its clamping voltage. The AOZ8851ADI-05 has a low on-state resistance (5Ω) and a high maximum reverse leakage current (50uA).

Conclusion

Overall, the AOZ8851ADI-05 is a versatile, high-performance TVS diode that is ideal for overvoltage protection and noise EMI filtering applications. The device is designed for use in a wide range of operating voltages, making it a practical choice for consumer electronics, automotive, and industrial applications. Its low on-state resistance and high maximum reverse leakage current provide robust protection from damaging energy transients.
