What is TVS tube TVS features and applications?

One, explain
TVS (TRANSIENT VOLTAGE SUPPRESSOR) or transient voltage suppression diode is a new product developed on the basis of the regulator technology. The circuit symbol is the same as the ordinary regulator diode, and the shape is the same as that of ordinary diode. When TVS tube Both ends are subject to instantaneous high-energy shocks, and they can suddenly reduce their impedance at very high speeds (up to 1 * 10-12 seconds) while absorbing a large current that clamps the voltage across its Predetermined values to ensure that the back of the circuit components from the impact of transient high-energy damage. TVS response speed is definitely 10e-12s faster than RC loop, without considering TVS breakdown voltage VBR, reverse critical voltage VWM, maximum peak pulse current IPP and maximum clamping voltage VC and peak pulse power PP. Select VWM Equal to or greater than the circuit operating voltage, VC is less than the protection device voltage, can measure the best (IPP), or estimate the power of the pulse, the election power of TVS.

Second, the classification
Suppression of reverse use of unidirectional TVS,
There are two-way TVS with communication

Third, the characteristics and application of transient voltage suppressor TVS
Transient Voltage Suppressor (Transient Voltage Suppressor) referred to as TVS, is a diode in the form of high-performance protection devices, and some literature also TVP, AJTVS, SAJTVS and so on. When the two poles of the TVS diode are subjected to a reverse transient high-energy impact, it can change the high impedance between the poles to a low impedance at a rate of 10-12 seconds, absorbing up to several kilowatts of surge power, Between the voltage clamp in a predetermined value, effectively protect the electronic components in the precision components, from a variety of surge pulse damage.
Edit this paragraph four key features

TVS tube because it has a fast response time, transient power, low capacitance, low leakage current, low breakdown voltage, clamping voltage easier to control, no damage limit, small size, easy to install, etc., has been widely used In the computer systems, communications equipment, consumer electronics, power, household appliances and other fields
