摘　　要：针对静电放电(electrostatic discharge,ESD)脉冲电流对电子设备内部芯片造成破坏,本文采用瞬态二极管(transient voltage suppressor,TVS)作为ESD抑制器件,分析了TVS的防护机理,考虑到高频情况下寄生参数的存在,建立了ESD保护电路模型.通过比较TVS抑制前后的负载两端的电压波形,研究其抑制性.最后通过实验验证了TVS的防护效果.Aiming at the electrostatic discharge （ ESD） pulse current undermining the interndevice, in the paper, transient voltage suppressor has been used as electrostatic discharge suppression device, the protec-tion mechanism of TVS has been analyzed. The circuit model for the ESD protection is propoexistence of parasitic parameters in high frequency. The suppression of TVS is studied by comparing the voltage wave-forms of the load before and after using TVS. Finally, the protection effect is verified by an experiment.
