With the spread of cloud computing and smartphones and the launch of 5G in 2020, the amount of data that moves on the internet is increasing as high-volume video and game data is added to existing documents, images, and sound data.
In addition, technologies are evolving, exemplified by AI, and a digital transformation (DX) is taking place as a result of the use of big data and the internet of things (IoT). To support these advances, however, large numbers of high-performance servers that can process large volumes of data will be needed. In conjunction with the increased performance of processors and various types of ICs, higher clock speeds of power supply ICs on server boards, high current power saving, miniaturization, noise countermeasures in data lines, and surge countermeasures have become urgent issues. Here, we introduce TDK products for addressing and solving these problems including the VLBU series of ferrite power inductors compatible with the high-efficiency needs of VR13 and VR14 applications, the FS series of DC-DC converters with embedded μPOL™, solutions using the ALT series of pulse transformers and ACM series of common mode filters and chokes, and chip varistors and ceramic transient voltage suppressors used for surge protection.

[Product Overview]
Chip varistors and TVS diodes are commonly used as over-voltage protection components.
Their structural design and manufacturing methods are completely different, but they offer similar characteristics with regard to protection from static electricity.
They generally can therefore be used interchangeably in a circuit, but there are cases where chip varistors are considered to be not suitable.
For historical reasons, many of the specification items given in catalogs and data sheets are different, which makes it difficult to compare characteristics based solely on these data, unlike in the case of capacitors and other general components.
The aim of this article is to clarify the difference between varistors and diodes and to introduce data that can be used to compare the two.
