Reference PDF, 181 KB, for the KA2923, an IC from the KA prefix series; the name contains only the part number and does not state its function, so that must be read from…

PDF covering the BF458 and BF459 transistors, a compact 49.2 KB file listed as a schematic but most likely a shared datasheet.

The name 3LP01S identifies this 28.1 KB PDF only by a component-style code with an S suffix; no laptop, board number or revision appears.

Short 28.6 KB PDF filed under schematics with the name 3LP01N, a code that resembles a discrete semiconductor part number with an N suffix.

The 2SK545 is covered by this 80.4 KB PDF, filed as a schematic but most likely a datasheet because 2SK numbers identify N-channel field-effect transistors in the…

The 2SK427 document is a 226 KB PDF filed as a schematic, but the 2SK prefix marks an N-channel field-effect transistor in the JIS numbering scheme, so it is effectively…

A 140 KB PDF named after the semiconductor 2SJ563, listed in the index under schematics.

The name of this 97.3 KB PDF gives nothing beyond 2SJ277, a JIS-style designation in which 2SJ marks a P-channel FET.

Filed as a schematic, this 93.5 KB PDF is identified solely by 2SJ274. The Japanese JIS 2SJ prefix stands for a P-channel field-effect transistor, so the content is most…

Named simply 2SJ226, this 84.5 KB PDF refers to a JIS-registered P-channel FET and most likely contains the part datasheet, even though it sits in the schematic section.

PDF reference, around 129 KB, covering two power ICs identified by marking codes: Qq for the SY8386BRHC and 3a for the SY8388C3RHC.

Listed under schematics but named only after a part number, this 91.6 KB PDF most likely holds the datasheet for the 2SC4188 transistor.

The 2SC4121 part number is the whole name of this 89.5 KB PDF; although typed as a schematic, it should be the datasheet for that NPN bipolar transistor, as the Japanese…

PDF of 47.7 KB named 2PD602A, apparently issue 4 of the document. The name identifies a part rather than a product or board, which points to a discrete semiconductor…
