In order to solve the problems caused by lightning,power switch operation,start-stop operation of each equip-ment on low-voltage power line and electrostatic discharge,electrical fast transient and dangerous surge voltage which affects the normal performance of electronic devices,or even burns circuits and equipments,it is proposed that the TVS can effectively pro-tect TN power system,DC power supply,signal circuit and transistor integrated circuit after the analysis of the characteristics, main parameters and working principle of TVS devices. Its application range is wide,and it is safe and reliable. The typical ap-plication of protection circuit of TVS devices in a variety of circuit design is pointed out in this paper. The adaptive elements should be selected according to the different protected objects and the related parameters of circuit.
