Voltage / Current / Temperature Protection Devices Voltage Protection Devices ThermoFuse Varistors Products & Technologies Apr. 2020 [Product Overview] What is the difference between Zener/TVS diodes and varistors? Four comparison aspects to consider with regard to usage 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.

Voltage / Current / Temperature Protection Devices Voltage Protection Devices ThermoFuse Varistors Applications & Cases Sep. 2018 [Application Note] How to Use NTC Thermistors for Inrush Current Limiting TDK has an extensive lineup of inrush current limiting NTC thermistors available. This article describes various example applications of these products, used for ICL (inrush current limiting) purposes to easily and effectively suppress inrush current. When power is first applied to electronic devices such as switching power supplies and inverters, an instantaneous current with an abnormally high peak will flow through them.<br> This is known as “inrush current” and if not addressed, can lead to problems such as semiconductor element failure or reduced service life of smoothing capacitors. However, our inrush current limiting NTC thermistors can provide protection against this phenomenon to prevent such undesirable effects.

For protection from a relatively large surge current (100A to 25kA), leaded disk varistors and SMD disk varistors are suitable. For protection from a larger surge current (approximately 25kA or more), block varistors, and strap varistors are suitable. This article describes surge protection device applications for LED lighting system, inductive loads such as motors, motor with an electromagnetic brake, SSR (solid-state relay), load dump and field decay, joint boxes and power conditioners of solar power generation systems, important devices using a lightning transformer, and high-energy surge in industrial devices.
