PDF titled only with the part number D304X, about 489 KB, filed as a schematic. The name gives no further detail on device type or manufacturer, so the contents are most…

PDF of 41.6 KB, catalogued as a schematic and named 3LN02M, which looks like a semiconductor part number with an M suffix rather than a board code.

PDF of 27.9 KB filed as a schematic under the code 3LN01S, which reads as a discrete component part number with an S suffix.

A 68.3 KB PDF bearing the name 2SD2324, a Japanese JIS designation for an NPN transistor, since 2SD marks NPN low-frequency devices.

Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

Short PDF, 43.6 KB, named after the 2SK2791 and listed as a schematic. The 2SK prefix marks an N-channel FET under the JIS scheme, so this is likely a compact datasheet.

PDF reference, 35.6 KB, for the 2SK2276, a Japanese JIS-registered device where the 2SK prefix indicates an N-channel field-effect transistor.

The file name gives nothing beyond 2SJ562, a JIS-style designation; the 2SJ prefix denotes a P-channel field-effect transistor.

This 170 KB PDF carries the part number 2SJ502 and is indexed under schematics. In JIS naming, 2SJ marks a P-channel FET, so the document is expected to be the datasheet…

The 2SJ225 is the only information this 91.8 KB PDF name provides; the 2SJ prefix in Japanese semiconductor numbering identifies a P-channel field-effect transistor.

Reference PDF for the 2SC5504 transistor, 48.9 KB, categorised as a schematic. Following JIS naming, the 2SC code denotes an NPN bipolar device, so this file is best…

The 2SC3747 transistor is covered by this 95.9 KB PDF, categorised as a schematic but by its name a datasheet for a single component.

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

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

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…

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.

Short PDF datasheet, 34.5 KB, for the 1N4728 Zener diode, the first and lowest voltage member of the 1N47xx 1 W Zener family.

Named simply 80SQ, this 125 KB PDF is indexed as a schematic, but the code looks like a series designation for a rectifier diode family rather than a circuit diagram…

A 179 KB PDF placed in the schematic section and named only 20TQ, with no device, board number or revision mentioned.

Spanish-language PDF titled semiconductores, 2.49 MB, with no device or brand stated in the name.

Small 540 KB PDF for the Compal-numbered LA-F312P motherboard; BDV in the name suggests boardview-style content, probably a component placement layout rather than a full…

Quanta AX2/7 schematic in PDF for board DA0AX2MB6E1, a Quanta ODM number built from the DA0 prefix, the project code and MB.

Schematic for the Quanta EL3 project, a 931 KB PDF. The name gives no revision or chipset details, so open the title block on the first pages to confirm which board…

PDF schematic, about 4.5 MB, for the AOC T2965M television, a model identified by its code in the file name.

Another copy of the Samsung RV410 schematic for the Scala 14L design, matching the companion file in size and likely identical in content, with a numbered suffix that…
