Difference between TVS transient suppression diodes and ESD diodes

For people who have just come into contact with the two products of TVS transient suppression diodes and ESD diodes, they may be confused, what is the difference between the two? ESD electrostatic protection diode and TVS diode the working principle of the two is the same, but in power, application, packaging form and other aspects are very different, the specific difference is as follows:

Difference between TVS transient suppression diodes and ESD diodes

1, ESD electrostatic diode, the main function is anti-static, however, anti-static requires a low capacitance value, generally between 1--3.5PF best; The capacitance value of TVS diode is relatively high.

2, ESD protection diode, mainly used in board level protection; TVS diodes are used for primary and secondary protection.

3. When choosing ESD electrostatic diodes, more attention is paid to the ESD rating (HBM/MM) and IEC61000-4-2 LEVEL of ESD diodes. High-speed USB and I/O attach great importance to the C of ESD diodes. When TVS diode is selected, the power and package form are looked at;

In practical applications, the two usually complement each other and are closely linked to give full play to their respective advantages and more effectively escort the circuit safety! The difference between TVS transient suppression diode and ESD diode is introduced here. If you want to know more, you can pay attention to Liyang semiconductor, which will be updated continuously in the later stage!

、封装形式等方面截然不同，具体区别如下：

　　TVS瞬态抑制二极管和ESD二极管的区别

　　1、ESD静电二极管，主要功能是防静电，然而防静电要求电容值低，一般在1--3.5PF之间最好;而TVS二极管的电容值却比较高。

　　2、ESD保护二极管，主要应用于板级保护;TVS二极管用于初级和次级保护。

　　3、再选用ESD静电二极管时，更多看的是ESD二极管的的ESD rating (HBM/MM)和IEC61000-4-2的LEVEL，高速的USB和I/O非常重视ESD二极管的C;而选用TVS二极管时，看的是功率和封装形式;

　　在实际应用中，二者通常相辅相成，紧密相连，各自发挥优势，更有效地为电路安全保驾护航!对于TVS瞬态抑制二极管和ESD二极管的区别就介绍到到这里了，想要了解更多可以关注里阳半导体，后期会不断更新的!
