Transient and surge protection for electronic products Transient and surge protection for electronic products | || ||2006-11-15 15:35:38 Safety and Electromagnetic Compatibility Network Source: Author: || ||[pic][pic] || Abstract: Voltage transients and surges in the use of electronic products will cause damage to electronic products. Therefore, the issue of voltage transient and surge protection has received more and more attention from designers. While pointing out the necessity of protection, the article also introduces the classification and characteristics of transient and surge protection devices, and focuses on the selection and application methods of transient and surge protection devices in three types of electronic products. || || Keywords: transient; surge; protective device ehq safety regulations and electromagnetic compatibility network || 1. The necessity of protection ehq safety regulations and electromagnetic compatibility network || As we all know, electronic products often encounter unexpected voltage transients and surges during use, which lead to damage to electronic products. The cause of damage is that the semiconductor devices (including diodes, transistors, thyristors and integrated circuits, etc.) in electronic products are burned or broken down. It is estimated that 75% of the failures of electronic products are caused by transients and surges. Voltage transients and surges are everywhere. Power grids, lightning strikes, explosions, and even people walking on carpets will generate tens of thousands of volts of electrostatic induction voltage. These are all invisible and fatal killers of electronic products. Therefore, in order to improve the reliability of electronic products and the safety of the human body, it is necessary to...
