How should TVs diodes be selected in electronic circuit applications and what should be paid attention to?

1、 The maximum DC value, rated standard voltage value and "high end" tolerance value of the protected circuit shall be clearly confirmed;

2、 The rated reverse turn off voltage of TVs tube shall be greater than or equal to the maximum working voltage of the protected circuit;

3、 The maximum clamping voltage of TVs tube shall be less than the damage voltage of the protected circuit;

4、 The maximum peak pulse power of the TVS tube must be greater than the peak pulse power of the protected circuit;

5、 After determining the maximum clamping voltage of TVs, the peak pulse current shall be greater than the transient surge current;

6、 Most DC protection circuits choose one-way TVs tubes, most AC protection circuits choose two-way TVs tubes, multi-channel protection circuits choose TVS Array Devices, and high-power protection circuits choose special protection modules;

7、 The influence of temperature change on the characteristics of TVs tube shall be considered. The TVS tube works between - 55 ° C and 150 ° C;

8、 In the process of using TVs tubes, considering the discreteness of TVs, the serial / parallel number shall be reduced as much as possible;
