Part datasheet for the 2SC4484, a 134 KB PDF. Japanese JIS numbering uses 2SC for NPN bipolar transistors, which identifies the device class here; nothing else is given…

Component data for the 2SK3021 in a 151 KB PDF, indexed here as a schematic. Following the Japanese JEITA convention, 2SK designates an N-channel FET, often found in…

Datasheet in PDF format, 229 KB, for the 2SD553 transistor, catalogued among schematics. Nothing besides the part type is stated in the name.

Datasheet PDF of 41.4 KB for the 2SA1249, placed among schematics in this index. The filename holds only the component number, and the 2SA prefix identifies a PNP…

2.1 amplifier schematic built around the TDA7294, by Technical Mriganka, in a 219 KB PDF.

PDF datasheet entry for the 2SK2986, 433 KB. Only the part number appears in the name; the 2SK prefix tells a technician it is a JIS-registered N-channel FET.

Datasheet PDF for the 2SA2062 transistor, 29.9 KB, the same size as the neighbouring 2SA2063 file, which hints at a shared document layout.

The smaller 77.9 KB PDF here carries the type number 2SC4449, indexed as a schematic but almost certainly a component datasheet.

Schematic PDF, 1.05 MB, labelled only U5A, with no brand or revision given. The document should open in any PDF viewer.

A 205 KB PDF bearing only the part number 2SC2710, catalogued as a schematic but most likely a component datasheet.

Component PDF for the 2N6847, 130 KB, indexed under schematics. The name holds only the JEDEC number, without a manufacturer, suffix or revision, so identify the source…

Compact 35.0 KB PDF datasheet for the 1N3595 part, indexed under schematics. The name carries no manufacturer or revision information, so check the document header for…

Schematic of a 2.1 channel amplifier based on the TDA2030A, from Technical Mriganka, in a 416 KB PDF.

Michaels International diode equivalents guide, a large 8.42 MB PDF catalogued here as a schematic but actually a cross-reference book.

CD4017 document in PDF form, 81.0 KB, for the CMOS decade counter with ten decoded outputs.

Catalogued as a schematic, this 31.8 KB PDF is named 2SK1443LS, pointing to a suffixed variant of the 2SK1443. The name does not clarify the LS suffix.

Datasheet document, by all indications, for the 2SJ189, a JIS-registered P-channel FET, held as an 83.5 KB PDF in the schematic section.

PDF datasheet material for the 2SD1194 transistor, about 138 KB, catalogued here under schematics.

Part number 2SA1533 names this 51.3 KB PDF, with an unexplained _E suffix; despite the schematic category it is presumably the transistor datasheet.

Datasheet-type PDF for the 2SA1939, roughly 170 KB, catalogued here as a schematic. The filename names only the component; the JIS 2SA prefix marks it as a PNP bipolar…

Datasheet in PDF form, 162 KB, covering the 43CTQ080 part, catalogued here as a schematic.

Reference PDF for the BQ24753A, a Texas Instruments charge controller part number commonly found on laptop motherboards, filed here at 2.06 MB.

Acer schematic in PDF for Inventec motherboard 6050A2292101, compressed into a 1.56 MB RAR.

Compact 27 KB PDF named 5HP01M, catalogued as a schematic but pointing to a single semiconductor component.

Datasheet-style PDF of 27.2 KB for the 2SK2682, a JIS-designated N-channel FET; it is listed under schematics but describes a single component.

The largest of this group at 186 KB, this PDF documents the 2SB1067 transistor and is catalogued as a schematic.

The name gives just 2N5638, so this 26.3 KB PDF has no board, device or revision information.

At 616 KB, 1B31.pdf is the largest of the 1B-coded files and is listed as a schematic, yet its name says nothing about device, maker or board revision.
