Product features and selection of ESD electrostatic protector

ESD electrostatic protector is an overvoltage, anti-static protection component, used to protect sensitive circuits in electronic equipment from the influence of ESD (electrostatic discharge), asThe purpose is to transfer the ESD stress from the sensitive component, so that the current flows through the protective component instead of the sensitive component, while maintaining the low voltage on the sensitive component; ESD staticThe electrical protector should also have low leakage and low capacitance characteristics, which will not reduce the circuit function; will not cause damage to high-speed signals, and will protect against multiple stresses.The function of the protection element will not be reduced.

What are the precautions for TVS devices?

1. Regarding the relationship between the peak value of absorbed power of transient voltage and the pulse width of transient voltage, the manual only gives the peak value of absorbed power under a specific pulse width, while the pulse width in the actual

What are the advantages of TVS diodes over other similar products?

TVS Diodes vs Zener Diodes: Compared to traditional Zener diodes, TVS TVS diodes have a larger P/N junction area. This structural improvement allows TVS to have stronger high voltage withstand capability while reducing voltage cut-off rate, so it has a be

The GDP of Shenzhen will rank first in China within 8 years, compared with that of Beijing and Shanghai

In 2016, Professor Wei Dazhi of Shenzhen University and Qin Shuo, a well-known media person, had a furious debate and compare over the economy trend of Shanghai and Shenzhen. Their viewpoints and conclusions are so different! I am Song Shiqiang from Kinghelm (www.kinghelm.net) and Slkor (www.slkoric.com), one of the top 50 punster writers in Huaqiangbei Shenzhen, I choose to support Professor Wei. To start with, I will analyze what Shenzhen is ahead of Beijing and Shanghai from the perspective of a Huaqiangbei economist. As Guangzhou is the administrative leader city of Guangdong province, I prefer not to commend it. My conclusion is that Shenzhen will be the top city with the best economic development in China in the foreseeable future.

Will TWS earphones make someone a new billionaire in Huaqiang North after Shanzhai mobile phones?

Huaqiang North Commercial Area is described as a place whose density of billionaires is the highest, known as an assembly line of billionaires, and the recent mass of which being the boom of Shanzhai mobile phones a few years ago. However, there are signs that billionaires in Huaqiang North have been shrinking even collapsing in recent years. According to the observation and estimation of Song Shiqiang, who is the CEO of Kinghelm (http://www.kinghelm.net), there will be a big trend this year, which ought to be grasped by the bosses engaged in original and second-hand trade, who are very good at seizing the opportunity. Therefore this is the reason why a momentum of the market blowout of Bluetooth earphones TWS occurred, which was tepid several years ago, and it is due to the progress of technology and reduction of cost. As the leading edge of the market, Huaqiang North will make lots of billionaires this time in the manner of assembly line (actually the production chain), right?

7 common interface types in the circuit

We know that when the sub -modules of the circuit system are transferred to data exchange, there may be some problems that cause the signal to "circulate" the signal that the signal cannot be normal and high quality. The types of their respective signals are inconsistent (such as sensor detection signal), etc. At this time, we should consider handling this problem well through the corresponding interface method. Let's explain the key points of the 7 common interface types in the circuit design: (1) TTL level interface: This interface type is basically old -fashioned. Starting from learning simulation circuits and digital circuits from college, for ordinary circuits, for ordinary circuits Design, TTL level

LM5025 chip knowledge of voltage type PWM controller

Today I said a voltage PWM controller, which is the LM5025 chip. Let's take a look at its basic parameters. Basic features: The chip built -in startup bias regulator, which has a programmable low -voltage lock output function (UVLO), voltage drive, 5V reference voltage, programmable soft startup function, and heat -cutting protection function. The input voltage is 13-90V. It has two packaging: TSSOP16 and WSON16 to choose from.

How to choose a transient inhibitory diode-TVS tube

The full name of TVS is Transient Voltage Suppressor, a transient voltage suppressor, which is a protective device. The tvs tube also belongs to the diode, but the characteristics are different from the diode. Its working principle is similar to the stabilization diode. It also uses reverse breakdown stable voltage. When the TVS tube in the circuit is impacted by reverse transient high -energy, it can turn the impedance between the two levels into low impedance at a very high speed (hundreds of skin seconds), and play a good surge power absorption effect. At the same time, the voltage between the two levels can be kept within a range to achieve the damage to the surge pulse of other metadata in the effective protection circuit. Tvs tube and ZENERDIODE two
