The origin of the name Bu508A transistor

This is the unified naming convention for transistors by the International Semiconductor Federation: B represents silicon material; U represents high-power switching transistor. 508 is the product registration number (indicating its parameters); A is his level code (for the same type of transistors, a certain parameter is used to distinguish between different levels). In short, there are various naming conventions for transistors, including domestic and European and American ones. Japanese and so on, currently the most widely used ones are Japanese, with less in Europe and America, and even fewer domestically produced ones.
