A 133 KB PDF for the 2SD1935, a transistor in the Japanese 2SD family, which the JIS standard reserves for NPN low-frequency devices.

Named 2SD1934 with an _E suffix, this 40.2 KB PDF is most likely the datasheet for that NPN transistor, since 2SD is the JIS prefix for NPN low-frequency types.

At only 34.4 KB, this PDF is a short reference for the 2SD1913 transistor. Under Japanese JIS part numbering the 2SD prefix identifies an NPN device for low-frequency…

Compact 30.7 KB PDF covering the 2SJ628, catalogued as a schematic but most likely a single-device datasheet given the part-number name.

Identified solely as 2SJ257, this 96.0 KB PDF most likely documents a P-channel FET, the device class assigned the 2SJ prefix in the JIS system.

Compact 32.0 KB PDF for the 2SC4747, categorized as a schematic in this index. The part number follows the JIS convention, in which 2SC denotes an NPN bipolar…

Datasheet-style PDF of 88.9 KB for the 2SC4361, listed in the schematic category although the file name holds nothing but the part number.

An 80.4 KB PDF covering the 2sb1260 transistor, listed in the index under schematics. No maker, package or device model is given in the name.

PDF of about 228 KB for the 2SA1297 PNP transistor, the 2SA prefix being the Japanese JIS designation for that device class.

Reference sheet for the 2SA1244 transistor in PDF form, 295 KB, listed as a schematic even though the name gives nothing beyond the part number and the file is most…

Part document for the 2SA1735 transistor, stored as a 151 KB PDF and catalogued under schematics.

Part reference for the 2SA1708, saved as a 154 KB PDF. No device, brand or board number is present in the name, only the component designation.

Very small PDF, only 16.5 KB, named 2pg352 and catalogued under schematics. The name is terse and gives no device, brand or board number, so it most likely holds a one…

Brief PDF document of 25.6 KB named 2pg351, listed as a schematic. Apart from the part-like code, the name carries no model, brand or revision, so treat it as a short…
