Covering the 2SC3811, this 45.7 KB PDF has an _E suffix in its name, which is not explained and may denote an edition or English version.

Named only after the JIS transistor number 2SC3461, this 110 KB PDF is listed as a schematic but is most probably a single-part datasheet.

Component reference for the 2SC3392, provided as a 155 KB PDF in the schematic category.

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

Datasheet-style PDF named for the 2SC5322, 122 KB, though the catalogue labels it a schematic.

Datasheet-style PDF, 96.2 KB, named only for the 2SC3089 and catalogued as a schematic.

The 277 KB PDF named 2SC2878 sits in the schematic category, though the JIS 2SC prefix suggests a datasheet for an NPN bipolar transistor.

A 52.7 KB PDF for the 2SB1672, which the JIS 2SB prefix identifies as a PNP transistor, so the file is expected to be a component datasheet even though it is catalogued…

PDF reference for the 2SA1682, a part number following the Japanese JIS scheme in which 2SA identifies a PNP bipolar transistor of the high-frequency class.

PDF of 42.0 KB covering the 2SB1392 transistor. The name provides only the part number; manufacturer, package and revision are not given.

Datasheet in PDF format for the 2SA1579 transistor, 36.6 KB. Only the part number is given in the name.

A 59.2 KB PDF describing the 2sb1275 transistor, filed as a schematic though the name points to a single part.

A 55.0 KB PDF titled with the 2SA1531 part number and an _E suffix, catalogued as a schematic yet most plausibly the datasheet for that transistor.

Small PDF document for the 2SA1524, filed under schematics but by its name a component data sheet for a discrete transistor.

PDF reference of 143 KB for the 2SA1419, a JIS-numbered part whose 2SA prefix denotes a PNP transistor in the high-frequency class.

PDF datasheet for the 2SA1338, a part whose 2SA prefix marks it as a PNP transistor intended for high-frequency service under the Japanese JIS convention.

Datasheet PDF of only 13.5 KB for the 2SA684 transistor, marked UTC, which indicates the Unisonic Technologies edition of this part.

PNP transistor documentation for the 2SA1150, provided as a 193 KB PDF. JIS naming uses 2SA for PNP bipolar devices, so although indexed as a schematic the file almost…

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

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

Titled 4GBL series, this 104 KB PDF is filed as a schematic but names no device, board or revision.

Labelled 80EPS08, this 80.7 KB PDF is classed as a schematic but carries a semiconductor part code in International Rectifier style, so it most likely contains a…

The 24WC257 is a Catalyst Semiconductor I2C serial EEPROM, and this 55.6 KB PDF, though catalogued as a schematic, is almost certainly its datasheet.

PDF document for the TDA7491P, a 1.45 MB file that is most likely the component datasheet rather than a board schematic, judging by the part-number name.

Nokia 6500 schematic in PDF format, 420 KB; the name does not specify whether it covers the 6500 classic or the 6500 slide, so check the board against the drawings…

PDF reference of 66.9 KB for the KA7500C, a pulse-width-modulation controller from the KA7500 family, compatible with the classic TL494 design.

PDF for the complementary TIP3055 NPN and TIP2955 PNP power transistors, 50.1 KB, indexed under schematics.

Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

Datasheet-style PDF for the 2SD1423, 41.0 KB, stored as a schematic; the trailing _E in the name is not explained by the file itself.

Component reference for the 2SD1993, a 45.5 KB PDF listed among schematics. Following Japanese JIS part numbering, 2SD identifies an NPN bipolar transistor of the…

Stored as a 190 KB PDF, this document is named after the 2SD1936, a JIS-registered NPN transistor.

File name 2sk198 is a JIS semiconductor number, so this 31.8 KB PDF, though catalogued as a schematic, is best treated as a brief component datasheet.

PDF document of 299 KB named for the 2SK117, most likely a datasheet even though the catalogue lists it as a schematic.

This small 31.6 KB PDF bears the name 2SK1444LS and is classed as a schematic. The name links it to a suffixed variant of the 2SK1444 without saying what LS stands for.

Brief 40.6 KB PDF for the 2SC4543, carrying an _E suffix whose meaning the name does not explain, and filed under schematics.

A compact 93.8 KB PDF carrying only the designation 2SC4476 in its name. Under JIS numbering the 2SC prefix identifies an NPN transistor of the high-frequency class, so…

Datasheet-style PDF of 119 KB for the 2SC4401, listed in the index under schematics although the name points to a single semiconductor part.

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

Compact 30.5 KB PDF for the 2SC3923, named by part number alone and sorted into schematics.

Single-part reference for the 2SC4864 in a 118 KB PDF, catalogued as a schematic. Apart from the part number, the name gives no information.
