TVS (transient voltage suppressors) diodes were developed to protect sensitive electronic components and devices in areas such as the automotive, industrial, and consumer markets. And TP6KE47A is one of the popular products among them. This article is to discuss its application field and working principle.

application field

The application field of TP6KE47A is extremely wide. On one hand, it is not only suitable for consumer applications such as personal computers, workstations, notebook computers, and mobile phones, but also industrial devices such as image acquisition cards and thermograph systems. On the other hand, it can also be used in automobile auxiliary equipment, current detection systems, medical equipment, and other fields.

TP6KE47A can effectively protect the connected circuit against high-voltage transients that are generated by electrical noise, electrostatic discharge (ESD), or lightning surge. Its very compact installation footprint can also fit into high-density circuit boards.

Working Principle

The working principle of TP6KE47A is straightforward. It relies on a reverse-biased structure that’s made up of two diodes, which are connected in series. When there’s a transient signal on the line, this structure will trigger the diode junction to break down, which in turn will start clamped to the power supply voltage. As a result, the voltage spike is neutralized, and the connected electronic circuits receive the appropriate level of protection.

The device also features internal breakdown protection. More specifically, a built-in fuse will trigger if the voltage spikes get too high, which ensures that the energized faults will be properly contained and protected.

To sum up, TP6KE47A is one of the most popular and widely used transient voltage suppressors due to its wide application field and straightforward working principle. It is designed to bring the utmost safety and stability to circuits and equipment in diverse industries and applications.
