PDF reference for the 2SC4881, 183 KB in size, categorised under schematics. Only the part code is given, which in JIS naming indicates an NPN bipolar transistor; maker…

Reference sheet for the 2SC5411, a PDF of 311 KB catalogued as a schematic. The name gives only the part number.

Covering the 2SC3914, this 30.1 KB PDF belongs to the family of JIS-numbered NPN bipolar transistors identified by the 2SC prefix.

File name 2SC3786 offers nothing beyond a transistor type number, and the 81.5 KB PDF is placed in the schematic category.

PDF document labelled as a schematic but named after the 2SC5387, a Japanese-numbered NPN bipolar transistor part number, so in practice it is almost certainly the…

A 177 KB PDF for the JEDEC part 2N5655, carrying an RE suffix whose meaning the name does not explain.
