[0002] Transient voltage suppressor, abbreviated as TVS, is a high-efficiency protection device in the form of a diode. When the two poles of the TVS diode are subjected to a reverse transient high-energy impact, it can change the high impedance between its two poles to a low impedance at a speed of the order of 10-12 seconds, absorb a surge power of up to several kilowatts, clamp the voltage between the two poles to a predetermined value, and effectively protect the precision components in the electronic circuit from being damaged by various surge pulses.
