Stored as a 101 KB PDF, this entry describes the 2SC3746, a JIS-numbered NPN bipolar transistor, and is filed under schematics in the catalogue. The name carries only the part number, with no suffix, revision or maker. The content should give electrical ratings, typical curves and mechanical outline. Use it to confirm which pin is base, collector and emitter before diode-mode testing, and to compare candidate replacements. Neighbouring part 2SC3747 has its own sheet, so do not mix the two up when sourcing parts.
