5KP14A-HRA

TVS - Diodes

TVS - Diodes are a common component in modern electronics and are widely used to protect sensitive electronic components from high voltage transients. The 5KP14A-HRA is a TVS diode that is designed specifically for over-voltage protection and surge protection. This article will discuss the application field and working principle of the 5KP14A-HRA.

Applications

The 5KP14A-HRA is designed for transient voltage suppression (TVS) applications. It can help to protect sensitive electronic components from the damaging effects of high voltage transients. This TVS diode can be used in a variety of applications, including automotive, avionics, telecom, consumer electronics, computers, and industrial control. It is particularly useful for applications that need robust surge protection, such as those in which lightning is expected.

Working Principle

The 5KP14A-HRA uses a specialized metal oxide varistor (MOV) to regulate the voltage across its terminals. When the voltage across the terminals exceeds the MOV’s rated breakdown voltage, the MOV will enter a high-conductivity state, allowing current to flow freely between the terminals and suppressing the transient voltage. This is commonly referred to as “clamping” the voltage. The 5KP14A-HRA also uses back-to-back Zener diodes to further limit the clamping voltage.

The 5KP14A-HRA also features a small inductance coil to form an inductive surge protection circuit. This circuit helps to absorb higher-energy transients and boosts the surge-handling ability of the device. Furthermore, The 5KP14A-HRA also employs a thermal shut-off mechanism to protect the MOV from overheating or excessive current.

Conclusion

The 5KP14A-HRA is a specialized TVS Diode that is designed to provide robust over-voltage protection and surge protection for sensitive electronic components. It utilizes a metal oxide varistor (MOV), back-to-back Zener diodes, an inductive surge protection circuit, and a thermal shut-off mechanism to provide robust protection against high voltage transients.
