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…

Reference sheet in PDF for the RJH60F7, an IGBT the file name rates at 50 A and 600 V. Devices of this type turn up in induction heating appliances, inverter welders and…

Part documentation for the 2SD2615, filed under schematics but by its name a component datasheet rather than a board drawing.

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 2SD2285 is documented in this 128 KB PDF. Its JIS part number, with the 2SD prefix, places it among NPN transistors intended for low-frequency circuits such as…

A 55.2 KB PDF named after the 2SK2348, a JIS-registered type whose 2SK prefix indicates an N-channel FET.

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…

Datasheet-style document for the 2SJ537, delivered as a 137 KB PDF though indexed as a schematic.

A compact 44.5 KB PDF labelled 2SJ520 and catalogued as a schematic. Because 2SJ is the JIS prefix for P-channel FETs, the document is best treated as a short datasheet…

Named after the JIS part number 2SJ267, this 91.8 KB PDF most likely documents a P-channel field-effect transistor, since the 2SJ prefix denotes that device class.

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

For the 2SC4742 transistor, this 32.2 KB PDF is indexed under schematics yet appears to be a component reference.

Indexed as a schematic, this 79.2 KB PDF is named 2SC4400 and should be the reference datasheet for that NPN bipolar transistor.

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…

The 2SC5777 is covered by this small 29.9 KB PDF, catalogued as a schematic but most likely a single-part datasheet.

PDF of 37.3 KB named after the 2SC5406 and listed as a schematic, though it is almost certainly a component datasheet.

Part documentation for the 2SC5302 in PDF form, 89.2 KB, placed in the schematic section of the index.

PDF of 61.5 KB for the 2SA1870, with a 1-2 tag in the name. That tag may indicate one part of a split document or a revision, but the name does not say which.

PDF, 52.3 KB, documenting the 2SA1177, a PNP bipolar transistor in the JIS 2SA numbering scheme.

A compact PDF of 48 KB filed under schematics, named after the part 2PB1219A with a trailing 3 that probably marks a document issue.

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…

PDF document of 164 KB with the bare name 40cpq035, indexed as a schematic. Nothing in the name points to a specific device, manufacturer or board revision; the string…

Indexed as a schematic, 36mt is a 53.9 KB PDF whose name is only a short code that resembles a component series designation rather than a laptop board number.

PDF filed as a schematic, named 28LV65, a code in the family of low-voltage parallel EEPROM memories.

Covering the 25AA320, 25LC320 and 25C320, this 383 KB PDF is listed as a schematic but is in practice the datasheet for a Microchip family of 32 Kbit SPI serial EEPROMs.

PDF of about 104 KB on the 24LC16 serial EEPROM, a 16 Kbit two-wire memory device. The name gives no revision or package detail, so treat it as general part…
