In recent years, e-cigarettes are a new type of smoking equipment. Because they produce a large amount of smoke and can be heated and atomized by changing different flavors of e-liquid at will, and do not produce harmful substances such as tar and carbon monoxide during use, they have become popular as soon as they are launched. It is deeply loved by smokers and has a tendency to replace traditional cigarettes. Represented by smokers in European and American countries. In order to pursue the effect of large vapor volume, some users often increase the heating power of e-cigarettes to 100 to 200W. Faced with such a large power, hardware circuit design is particularly important; the use of lithium batteries will inevitably cause problems due to the circuit board. Over?current or short circuit may lead to battery explosion, so how to improve the safety of e-cigarettes is also a very critical point.

In addition, there is some over-temperature protection. After all, the heat generated on a 100W power circuit board cannot be underestimated. If the temperature is too high, it will increase the possibility of explosion or fire. If the protection circuit fails due to static electricity from the human body while using the equipment, the protection circuit will be ineffective!

SOCAY?Electronics（www.jgmf.cn）?has been devoted to the field of static electricity rectification and protection for hundreds of years. We are here to meet you. Taking advantage of this trend, we launched the electrostatic diode SE05N6S21HB, which is widely used in electronic cigarettes.
