Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

Filed under schematics, this 80.8 KB PDF is titled with the part number 2SC2857. The JIS 2SC prefix designates an NPN bipolar transistor, so the content is most likely a…

Named after the JIS part number 2SC2816, this 50 KB PDF appears in the schematic category but most likely contains the datasheet of an NPN bipolar transistor, as the 2SC…

A compact 33.0 KB PDF named for the 2SB647, a PNP transistor according to the JIS 2SB prefix; although indexed as a schematic, it is most likely the part datasheet.

Component datasheet for the 2SB1644, a small 48 KB PDF catalogued under schematics. JIS numbering places any 2SB part among PNP bipolar transistors for low-frequency…

Small 39.6 KB PDF containing the datasheet for the 2sb1616, catalogued as a schematic entry.

Datasheet PDF covering the 2SA1588, 215 KB in size, which suggests several pages with curves and package details.

The 2SA1572 transistor is documented in this 49.4 KB PDF. No board or equipment model appears in the name, so treat it as a component datasheet.

Datasheet PDF for the 2SB1274, 34.4 KB in size and likely a concise sheet. The name offers only the part number.

PDF document for the 2SA1200, a part number in the Japanese JIS 2SA series, which designates PNP bipolar transistors.

PDF of 46.9 KB filed under schematics but named after the component 2PC4617, with a suffix 3 that likely denotes the document issue.

PDF datasheet of 52.2 KB for the 2N2369 NPN switching transistor, placed in the schematic section.

A PDF document for the 1SV215 part, catalogued as a schematic but most likely a component data sheet.

Documentation for the 1SV172 diode, stored as a 72 KB PDF and indexed as a schematic. The 1SV numbering is a Japanese JIS diode designation that Toshiba applies to…

Documentation for the 1SV312 part in PDF form, roughly 72 KB and classed as a schematic.

Only the part number 1SS336 appears in this 68.3 KB file name, and the PDF is filed under schematics.

Nothing beyond the code 1SS309 appears in the name of this 69.5 KB PDF, so no device or board can be tied to it.

With the name 1N756A and a size of 50.3 KB, this PDF appears to be the datasheet for a single JEDEC 1N diode type in its A grade, filed under schematics.

The 1SR156-400 document is a 120 KB PDF catalogued as a schematic, though its name follows a discrete component part-number style and carries no device or board…

Compact PDF of about 91 KB covering the 93C46 serial EEPROM, the 1 Kbit member of the 93-series Microwire family; the _3 suffix appears to mark a document revision or…

Only the number 271001 appears in this 134 KB PDF name, and it is listed as a schematic, though the pattern suggests a 27C1001-style 1 Mbit EPROM datasheet rather than a…

Small 45.6 KB PDF listed among schematics under the code 75SLQ030. The name gives no model, brand or revision; it reads like a discrete power semiconductor part number…

Small 52.8 KB PDF filed under schematics with the code 70eps08 as its only identifier. No laptop brand, model, PCB number or revision appears in the name.

Catalogued as a schematic, this 130 KB PDF is named 64LCXX, where the XX looks like a placeholder covering several capacity or variant codes of one series.
