摘要
为了某防护模块性能设计的需要,研究常用防护器件瞬态抑制二极管(TVS)的电磁脉冲防护能力。选取三种常用的TVS器件,在静电电磁脉冲和方波脉冲试验条件下,进行电磁脉冲响应规律的测试研究。测试结果表明,一般类型的TVS器件的响应时间普遍高于1ns,脉冲上升沿1ns内的能量就无法被TVS器件在第一时间内吸收,会影响或损伤被防护的电子设备,甚至TVS防护器件。综合钳位电压值和钳位时间,其中一种TVS器件在测试电压300V以内的防护性能可满足模块的防护要求。而另外两种TVS器件对于快上升沿电磁脉冲的防护性能较差,在此环境下无法达到电磁脉冲防护要求,但在其它工作条件下可参考它们的特性数据进行选择应用。
In order to design the performance of a protective module,the electromagnetic pulse protection capability of the transient suppression diode(TVS)is studied.Three kinds of TVS devices,which are used in the experimental condition of static electromagnetic pulse and square wave pulse,are studied.Test results show that the response time of the general types of TVs devices are generally higher than 1ns,pulse rise along the 1ns energy can not be absorbed by the TVS device in the first time,will affect or damage is door of electronic equipment,and even TVS door device.Integrated clamp voltage value and clamp time,one kind of TVS device in the test voltage of 300V can meet the protection requirements of the module.And the other two TVS devices for fast rise along the electromagnetic pulse protection performance is poor,in this environment cannot reach electromagnetic pulse protection requirements,but in the other work conditions can reference their characteristics data selection and application.
