The 2SC3996 is covered by this 91.9 KB PDF, sorted under schematics although a name consisting only of a part code usually means a datasheet.

For the 2SC3597 transistor, a 119 KB PDF filed as a schematic but containing component data.

Datasheet for the 2SC3495 in a 91.6 KB PDF, indexed in the schematic category. By Japanese JIS naming, the 2SC prefix identifies an NPN bipolar transistor designed for…

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

Named for the 2SC2898, this 50 KB PDF is categorised as a schematic but should contain the datasheet of an NPN bipolar transistor, as indicated by the JIS 2SC prefix.

A 147 KB PDF whose name is just 2SC2881, catalogued as a schematic. By JIS numbering this is an NPN bipolar transistor, and the file is most likely its datasheet rather…

This 183 KB PDF takes its name from the 2SC2840 and is indexed as a schematic. In Japanese JIS designations, 2SC means an NPN bipolar transistor, so the document is…

The 2SB1674 named here is, under JIS conventions, a PNP bipolar transistor; this 52.6 KB PDF, despite its schematic category, is therefore most likely the datasheet.

Here is a 122 KB PDF for the 2SA1696, a semiconductor numbered under the Japanese JIS system and listed among schematics, though a part-coded file like this is normally…

The 2SA1564 is covered by this 90.3 KB PDF, which is labelled as a schematic but named after a discrete component.

A 30.8 KB PDF named for the 2SA1522, a part number in the Japanese 2SA series of PNP transistors.

PDF for the 2SA1512, 41.0 KB, with an _E suffix in the name whose meaning is not stated, possibly a document edition or language variant.

Part documentation for the 2SA1415 transistor, delivered as a 116 KB PDF and indexed as a schematic.

Component sheet for the 2SB779, delivered as a 40.5 KB PDF. It is catalogued as a schematic, though a name consisting of a bare part number indicates a datasheet.

Transistor datasheet in PDF form for the 2SA720A, 42.4 KB, with an _E suffix whose meaning the name does not state.

Component documentation for the 2SA1314 in PDF format, 162 KB. The type field says schematic, but the name consists only of the part code, which normally means a…

Datasheet PDF, 149 KB, for the 2SA1710 transistor; the file name gives no further model or board details.

This 26.1 KB PDF, placed in the schematic section, is named after the 2N6517, part of the JEDEC 2N numbering used for discrete transistors and similar devices.

Catalogued among schematics, this 213 KB PDF carries the part number 2N6426 and an RE suffix whose meaning the name does not give.

Catalogued among schematics, this 254 KB PDF is titled with the JEDEC part number 2N5630 plus an RE suffix of uncertain meaning.

PDF datasheet for the 2N5457 N-channel JFET, 111 KB, filed under schematics. The RE suffix in the name is not explained and may mark a reissued or alternate vendor copy…

Part datasheet for the 2N5307, a 57.5 KB PDF classified as a schematic in this catalogue.

Reference sheet for the 1T368A transistor, 40.5 KB in PDF format and indexed under schematics.

A 48.1 KB PDF covering the 1T413 transistor, catalogued as a schematic entry. Its designation follows the Soviet system, with 1T identifying a germanium device of the…

The 1T404 code is all the name reveals about this 52.4 KB PDF, which is listed as a schematic. No device, maker or board number is stated.

Filed under schematics, 1T402 is a short PDF of 52.5 KB whose name holds only a component number. Nothing indicates which device or board it relates to.

PDF reference for the 1SV329 diode, listed among schematics though its size suggests a concise data sheet.

Datasheet PDF for the 1N4001 rectifier, 42.6 KB, filed under schematics. The name includes rev5 and dx, which appear to indicate a document revision and a vendor or…

Only 34.2 KB, this PDF is named 1N957, a JEDEC 1N diode designation, and is better described as a component datasheet than a schematic.

Code 50WQ06F is the only clue in this 38.5 KB PDF, filed under schematics and naming no laptop, brand or board.

Filed under schematics, this 77.3 KB PDF named 30SLJQ030 is most probably the datasheet for a discrete rectifier, the lowest voltage code among the 30SLJQ files indexed…

PDF of 217 KB named for the 24C00, a very small I2C serial EEPROM of 128 bits (16 bytes).

A 127 KB PDF filed under schematics and named 20ETF08S. It gives no device model, board number or revision.

PDF schematic named only SY3, a 551 KB document without any brand, model or revision information in its name, so its identity must be confirmed from the title block…
