Overview:

The circuit symbol of TVS is the same as that of ordinary voltage regulator tubes. The volt-ampere characteristic curve is shown in the characteristic diagram. The forward characteristics are the same as those of ordinary diodes, and the reverse characteristics are typical of PN junction avalanche devices. Under the action of the surge voltage, the voltage between the poles of TVS rises from the rated reverse turn-off voltage VWM to the breakdown voltage VBR, and is broken down. With the appearance of the breakdown current, the current flowing through the TVS will reach the peak pulse current IPP, while the voltage at both ends is clamped below the predetermined maximum clamp voltage VC. Subsequently, with the exponential attenuation of the pulse current, the voltage between the poles of TVS also continues to decline, and finally returns to the initial state, which is the process of TVS inhibiting possible surge pulse power and protecting electronic components. When the TVS poles are subjected to reverse high energy impact, it can change the impedance between the poles from high to low at a speed of 10-12S, absorbing up to several kilowatts of surge power, so that the potential clamp between the poles is located at a predetermined value, effectively protecting the components in the electronic equipment from the damage of the surge pulse.
