Which ESD electrostatic protection devices are commonly used

release time:2022-03-17Author source:SlkorBrowse:609

Paying attention to the market of ESD electrostatic protection devices also found that there are still many types of this type in the market, but if you want the right choice, some people don't know much about these electrostatic protection devices. Let's take a look at the commonly used ones. This will make it easier for you to choose.

ESD

During ESD electrostatic protection, the most commonly seen is a chip varistor, and the other is an ESD diode. These two are very common electrostatic protection devices, but they should also be used when selecting them. Pay attention to whether it can be effectively de-protected, especially how it works in the circuit. Let's take a look at which criteria to see it when choosing, and whether it will produce better protection. In fact, when choosing a word, it mainly depends on its nominal value. In addition, it also depends on what its voltage and current are, that is, what kind of current and voltage will short-circuit. In the end, this involves other electronic components. protection of.
Then if it is a chip varistor, it is a linear resistive element, that is, when the voltage is relatively large, the resistance will be small and lead to conduction, thus producing effective protection. And the use of this kind of diode is precisely because of this low impedance and good reliability. Many circuits basically use this kind of semiconductor diode as protection, especially when this kind of diode is used, it is like a etc. Effective capacitors can be better protected, and it has become the best choice for many circuit protection.
In the electronic component market, many ESD electrostatic protectors or electrostatic dischargers are also found. In fact, when choosing, what should be understood is whether the response time is fast and what is the low clamping voltage? Of course, the most important thing is what the high current surge withstand capability is. Through the above three points, you can know what kind of electrostatic protection is very good, especially if you choose this kind of high-quality and high-standard anti-static equipment, it can play a real protective role and can truly protect the circuit.
