Specification sheet for the 2SC3600 transistor in PDF form, 136 KB, listed under schematics.

2SC3598 datasheet in a 119 KB PDF, catalogued in the schematic group. Only the part number appears in the name; under Japanese JIS numbering the 2SC prefix identifies an…

Here the PDF, about 110 KB, is labelled with the bare part number 2SC3459 and listed as a schematic.

Part data for the 2SC3152 NPN transistor, stored as a 103 KB PDF in the schematic section.

Part number 2SC2911 is all the 43.6 KB PDF name states, and the index lists it as a schematic.

A 45.3 KB PDF titled with the JIS transistor number 2SC2909, filed under the schematic category.

A 51.5 KB PDF named for the 2SC1573 with an _E suffix, categorised as a schematic. Since 2SC is the JIS prefix for NPN bipolar transistors, this is best read as a short…

Named after the 2SC1383, this 51.4 KB PDF is listed as a schematic, yet the JIS prefix 2SC denotes an NPN bipolar transistor, so expect a part datasheet.

A 58.1 KB PDF labelled as a schematic and named after the 2SC1215, an NPN transistor by Japanese JIS naming, so it should be the datasheet for that discrete part.

Listed among schematics, this 60.7 KB PDF refers to the 2SC1047, which under JIS numbering is an NPN bipolar transistor; the content is therefore most likely a part…

Component datasheet for the 2sb1580, 64.2 KB in PDF and indexed as a schematic. The 2SB prefix comes from the JIS standard and indicates a PNP bipolar transistor for…

Datasheet for the 2sb1566 PNP bipolar transistor in a 37.5 KB PDF. The 2SB label, per the JIS convention, means a PNP device for low-frequency circuits; the file name…

Component documentation for the 2SA1591, an 89.4 KB PDF. Only the part number appears in the name; no revision or manufacturer is given.

A compact 19.1 KB PDF for the 2SA1580, small enough that it is probably a one- or two-page summary sheet. No other details are present in the name.

Filed as a schematic, the 51.8 KB PDF for the 2SA1534 carries an _E suffix in its name whose meaning is not stated; the content is most likely the datasheet for this JIS…

Component reference for the 2SA1521 transistor, stored as a 30.2 KB PDF and filed under the schematic category.

PDF of 41.0 KB for the 2SB873, with an _E suffix whose meaning the name does not explain.

A 39.8 KB PDF filed under schematics that covers the 2SB835 transistor, with an _E suffix in the name whose meaning is not stated and may simply denote an edition or…

An 86 KB PDF covering the 2SA1896, a PNP bipolar transistor under the Japanese JIS 2SA designation.

The 2SA1869 is covered by this 174 KB PDF, a PNP bipolar transistor in the Japanese JIS 2SA series.

Short 31.2 KB PDF for the 2SA1864, a PNP bipolar transistor in the Japanese JIS 2SA family.

Small 81.5 KB PDF named after the 2SA1724 part number and filed under schematics. Nothing else in the name identifies a product or circuit board.

Component PDF of 133 KB for the 2SA1705, filed as a schematic but named after the part only, with no device or board information.

PDF reference of 51.6 KB named 2N1613, placed in the schematic category. The 2N prefix follows the JEDEC numbering used for discrete semiconductors, so the content is…

A 52.2 KB PDF in the schematic listing, labelled simply 2N6487, a part number from the JEDEC 2N discrete semiconductor series.

Filed as a schematic, this 271 KB PDF is named after the discrete part number 2N5684 with an unexplained RE suffix, which may indicate a reissued edition.

Part number 2N5551 is the sole identifier of this 74.3 KB PDF, listed as a schematic. Under the JEDEC 2N scheme the file is most plausibly a datasheet for the discrete…

Component datasheet in PDF form for the 2N5458, an N-channel junction FET usually found in TO-92 packages, catalogued here as a schematic-type document of about 130 KB.

Part number 1T409 is the only information in the name of this 49.5 KB PDF, which is catalogued as a schematic.

The file is a 56.2 KB PDF listed under schematics and labelled 1T408, with nothing else in the name to tie it to a specific product or board.

Named 1T405A, this 69.4 KB PDF is filed as a schematic. The A suffix marks a variant of the 1T405 code, and the two should not be assumed interchangeable.

Part code 1SV234 is the only detail in the name of this 65.8 KB PDF, which is filed as a schematic. No equipment model or board number is stated.

The 1SS190 is the only information in this file name, apart from an underscore. The 68.1 KB PDF sits under the schematic category.

The 1SS398 is the subject of this 78.2 KB PDF, which is catalogued as a schematic but is likely a single-part datasheet.

Only the part number 1SS374 is given in the name of this 68.5 KB PDF, so treat it as a component specification rather than a board schematic.

Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified.
