Popular transistors in Japan

Arran Cameron
Does anybody know the device numbers of popular transistors in Japan used by hobbyists, education, prototyping etc?


The devices that would be used when we use a 2N2222 or a BC548?


Many, but not all, Japanese transistors have part numbers beginning with 2S followed by a letter denoting the type of the device followed by a number.

    Have a look at Tower's International Transistor Selector - Great book, has equivalents for everything and a good explanation of Japanese vs Euro and US transistor types.
