The thyristor module is a high-power semiconductor device with a four-layer structure of three PN junctions in the form of module packaging. The volume of this thyristor module is very small and the structure is very compact. It has a great effect. There are many types of thyristor modules, such as crimping thyristor modules, welding thyristor modules, etc. Many people are not very clear about the difference between the two. The details are as follows. 

① In terms of current, the welding type module can achieve 160A current, and the current of the crimping type module can reach 1200A, which means that the module lower than 160A, not only the welding type, but also the crimping type. 

②In terms of appearance, the welding-type module is far less good than the crimping-type one. The crimping-type is one-piece molding, and the technology is very standard. There may be traces of welding in the local area of the welding-type. time has no effect.

③As we all know, the market share of crimp-type thyristor modules is very large, and many companies use crimp-type thyristor modules. The reason for this may be that its appearance is very beautiful. In terms of price, the cost of welded thyristor modules is much lower than that of crimped thyristor modules.
