English-edition datasheet, as the _E suffix commonly indicates, for the 2SC3941 NPN bipolar transistor, 50.9 KB PDF filed under schematics. The suffix meaning is a convention rather than something the name confirms. JIS 2SC parts are NPN transistors, and the sheet should list ratings, characteristics and the package outline. Consult it to identify pins before measuring and to choose a replacement with matching limits, after checking that the C3941 marking and package on the board agree.
