TVS - Diodes are an important component in the world of electronics, and they are often used for high-voltage protection, providing a valuable safeguard against electrostatic discharge (ESD). The P4KE82CAHR0G is one such TVS diode, which offers high levels of protection from voltage transients and overloads. In this article, we will explore the application field and working principle of the P4KE82CAHR0G TVS diode.

The P4KE82CAHR0G TVS diode offers superior performance in terms of surge and ESD protection. It can protect up to eight lines from voltage transients that range from 6 to 32 volts, making it suitable for a wide range of applications. It is also designed to protect against overvoltage caused by power line surges, ESD and lightning, and it can effectively reduce voltage surges to safe levels. This makes the P4KE82CAHR0G a great choice for communications, automotive, and industrial applications.

The P4KE82CAHR0G TVS diode is an example of a unidirectional diode, meaning that it only allows current to flow in one direction. It is also a diode array, meaning that it contains multiple diodes in a single package. The P4KE82CAHR0G is composed of eight discrete diodes, each with a breakdown voltage of 23 volts. This means that if the voltage across the diode exceeds 23 volts, then the diode will activate and begin to limit the current that can flow through it.

The P4KE82CAHR0G operates by utilizing the avalanche effect. This is a form of breakdown where the electrical current passing through the diode is increased, due to the decrease in the built-in potential barrier. When a voltage surge or ESD occurs, it causes an increase in electric field strength, which leads to a rapid increase in current. This increased current causes further reduction in the potential barrier, which further increases the current flow, creating a chain reaction known as avalanche breakdown.

The P4KE82CAHR0G\'s small package size and low package capacitance make it ideal for use in high-density applications. Additionally, its low clamping voltage and fast response time make it well-suited for protecting sensitive circuits from voltage transients and ESD. Furthermore, the P4KE82CAHR0G TVS diode is RoHS and REACH compliant, making it an ideal choice for products that need to meet the latest environmental regulations.

In conclusion, the P4KE82CAHR0G TVS diode is a versatile and reliable component that offers superior protection for sensitive circuits against voltage transients and ESD. Its small package size and low package capacitance make it ideal for high-density applications, while its proven avalanche breakdown protection makes it a great choice for applications where durability is a must. With its high ratings and RoHS and REACH compliance, the P4KE82CAHR0G is an excellent choice for manufacturers looking for reliable and high-performance TVS diodes.
