Introduction

A5KP28CA-G is one of the best and most commonly used TVS - diodes. TVS Diodes, also known as Transient Voltage Suppressor Diodes, are used to protect various types of electronic equipment from electric surges. In this article, we will discuss the application field and working principle of A5KP28CA-G.

Application Field

A5KP28CA-G is suitable for various kinds of electronic equipment protection, such as computer motherboards and peripherals, mobile phones, automotive electronics equipment, smart meters, LED displays and more. It can protect the equipment from transient voltage surges, including both EMC and lightning surge.

The popularity of A5KP28CA-G is mainly due to its high reliability and remarkable ability to suppress accurately the transient voltage. It can effectively absorb and reduce the surges, ensuring that the voltage does not exceed the safety range, and that the electronic equipment is not damaged by the high voltage.

Working Principle

The working principle of A5KP28CA-G is based on the avalanche breakover principle. When an external surge current is applied, the depletion layers between the N-type base regions and the P-type regions expand, leading to increased resistance and breakover action. This causes the TVS diode to turn on and clamp the voltage, thus preventing the voltage from exceeding the safety range and damaging the electronic equipment.

A5KP28CA-G can provide various levels of protection. For example, when the surge voltage is extremely high, the TVS diode can quickly block the voltage, complete the clamping action in the shortest possible time, and avoid the harmful effect of high voltage on electronic equipment. In addition, it can also provide continuous drain current protection, which means it can limit the maximum allowable current flowing through the equipment without causing damage.

Conclusion

In conclusion, A5KP28CA-G is one of the best TVS - diodes available on the market. It can be used in many different application fields, and it relies on the avalanche breakover principle to prevent transient voltage and current surges from damaging electronic equipment. Therefore, it is an ideal choice for many electronic device manufacturers.
