TVS Diodes

Transient Voltage Suppression (TVS) Diodes are components that can limit and reduce transient over-voltage. TVS diodes are mainly used to protect sensitive electronic circuits in power and communication lines. In this article, we will focus on the application field and working principle of 5KP30AHE3/73.

Application Field of 5KP30AHE3/73

The 5KP30AHE3/73 is a unidirectional TVS diode with an available stand-off voltage of 30V. It can handle a transient voltage of up to 8000W peak pulse power when applying a 10/1000 μs waveform. This TVS diode is primarily used in high-voltage environments and suitable for small and medium size signal lines. Some of the applications include telecommunications, wireless transmissions, event broadcast, direct broadcast, automotive electronics, and military and aerospace.

Working Principle of 5KP30AHE3/73

The working principle of the 5KP30AHE3/73 is based on the principle of a Zener diode. When a high voltage transient deteriorates a circuit, the TVS diode kicks in and limits its voltage to the specified stand-off voltage. In other word, TVS diode is a unidirectional protection device that can provide the circuits with simple, reliable, and effective protection against electrical transients.It consists of a metal oxide avalanche diode that responds quickly to transients, and an additional zener diode that provides the stand-off voltage. The avalanche diode can clamp the transient voltage, but the zener diode is designed to limit the follow up of the transient voltage and current spike.

Under normal circumstances, the 5KP30AHE3/73 operates as an open circuit. When a transient voltage arises, the avalanche diode will respond quickly and differential current starts to flow. This causes the avalanche diode to enter into an avalanche breakdown. Meanwhile, the zener diode limits the differential voltage to the specified stand-off voltage and isolates the source of the transient voltage from the rest of the circuit. This allows the TVS device to limit the voltage to the desired level without loss of signal.

Conclusion

To sum up, the 5KP30AHE3/73 is a unidirectional TVS diode with an available stand-off voltage of 30V. Its main application fields include telecommunications, wireless transmissions, event broadcast, direct broadcast, automotive electronics, and military and aerospace. Moreover, these TVS diodes operate by using a combination of an avalanche diode and a zener diode, which allows it to quickly respond to transient voltage and limit it to the specified stand-off voltage.
