Small 30.2 KB PDF for the 2SA1968LS, a variant of the 2SA1968 identified by the LS suffix; what that suffix denotes is not explained in the name and should be confirmed…

At 320 KB, this PDF for the 2SA1163 is the largest of this group of 2SA files and likely a full manufacturer datasheet with characteristic curves.

Datasheet for the 2N7053 in a 314 KB PDF, categorized with schematics. The size matches that of the 2N7052 file and both may come from a shared family document, though…

At 329 KB this is the largest sheet in the group, a PDF catalogued as a schematic for the 2N6515 with an unexplained RE suffix.

Very small PDF of 26.3 KB named with the part number 2N5639 and nothing else. Listed as a schematic, it is most plausibly a short datasheet, since 2N codes are JEDEC…

A compact 32.6 KB PDF for the 2N3773, a JEDEC-registered 2N-series transistor; despite the schematic label it is a component datasheet rather than a circuit drawing.

1N750A is the part behind this 50.3 KB PDF, a datasheet for a member of the JEDEC 1N746A to 1N759A zener diode family, catalogued here under schematics.

Datasheet for the 1N5402, a 200 V member of the 3 A 1N5400 rectifier family, kept as a 43.4 KB PDF and listed under schematics. The name states only the part number.

Revision 2 of a datasheet for the 1N5400, the 50 V base grade of the 3 A rectifier series, supplied as a 44.9 KB PDF and indexed under schematics.

Series datasheet for the 1N5221 to 1N5281 zener range, a compact 35.5 KB PDF filed as a schematic.

Sister document to the 45 V variant, this 85.4 KB PDF for 175bgq030 is filed as a schematic but reads as a component datasheet for a Schottky rectifier, the 030 suffix…

A datasheet-style PDF of 80.7 KB for the 162cnq030, categorised as a schematic in this index.

At 43.6 KB, this PDF titled 152cmq030 is listed among schematics, yet the name is a rectifier part code for a common-cathode Schottky pair, commonly a 30 V grade.

Indexed as a schematic, this 83.3 KB PDF named 150k most likely documents a stud-mount power rectifier diode series, as the short code follows the pattern used for such…

Named only 50WQ10F, this compact 39.2 KB PDF sits in the schematic category but gives no laptop model, brand or board number.

Catalogued as a schematic, 25F080A is a 380 KB PDF whose name looks like a serial memory part code, making a chip datasheet the likely content.

PDF of 329 KB named 25C040, indexed as a schematic although the name points to a 25-series SPI serial EEPROM, where 040 conventionally denotes 4 Kbit capacity.

Filed under schematics, this 357 KB PDF is named after the 25AA640 and 25LC640, which are Microchip SPI serial EEPROMs of 64 Kbit capacity, so it is most likely the…
