功能上兼容 只是静电泄放时回路有点区别，前者先经过等效二极管再过等效稳压管，后者先经过等效稳压管再过等效二极管

Creating a Bidirectional Diode
TVS diodes are inherently unidirectional. A bidirectional device can be created by combining two unidirectional diodes, as shown in Figure 5. The electrical characteristics of a common cathode and common anode device are typically equivalent. The clamping voltage (VC) of the composite bidirectional device is equal to the breakdown voltage (VBR) of the diode that is reversed biased, plus the diode drop of the second diode that is forwarded biased.

二楼说的很详细

实际应用应该没差别。

基本没啥差别。

没差别吧，只是标识的方法不同，都代表双向。
