PDF schematic for an HP Pavilion dv5 with an AMD processor platform. The file name lists no motherboard number, ODM project or revision, so read the title block on the…

Schematic PDF identified only by the codes H0225-3, 48.4KH17.031 and LDB1; the name does not state a laptop brand or model.

PDF of 352 KB for the 74AC14, a hex inverter with Schmitt-trigger inputs from the advanced CMOS family, listed under schematics.

Reference sheet for the 74AC04 hex inverter, an advanced CMOS logic part, supplied as a 301 KB PDF in the schematic category.

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 for the CEP540N transistor, with the name noting 100 V and 36 A ratings, about 626 KB in size.

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

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…

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…

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

Only the part number 2SJ275 appears in the name of this 97.0 KB PDF. That code follows Japanese JIS numbering, where 2SJ indicates a P-channel field-effect transistor…

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 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.

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

A PDF document for the 2SC4884, filed under schematics but by its name a component datasheet rather than a board diagram.

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.

A brief 48.3 KB PDF on the 2SC3504, catalogued as a schematic but containing transistor data.

Compact 49.5 KB PDF for the 2SC3354, with an _E suffix in the name that may indicate an English-language edition, though the name does not confirm it.

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

The 2SA1734 is the subject of this 183 KB PDF, which carries only the component number in its name.

Short PDF document, 47.9 KB, whose name points to the component 2PB710A, with the suffix 6 likely indicating a revision of the sheet.

PDF of 25.8 KB carrying only the code 2pg302 in its name and filed under schematics. No laptop model, board number or manufacturer is stated, so the content cannot be…

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 of 168 KB filed as a schematic and named 2N2219A, a designation in the JEDEC 2N numbering used for discrete semiconductors.

A 54.5 KB PDF filed as a schematic and identified only by the short code 51HQ, with no brand, model or revision stated.

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…

A compact 75.6 KB PDF indexed as a schematic but named 31DQ09, a code that looks like a rectifier diode part number, not a motherboard.

Part-number-style PDF, 176 KB, labelled 27lc040 and listed here as a schematic. The pattern matches the 27-series UV or OTP EPROM family, with LC typically denoting a…

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…

PDF reference, 274 KB, for the 24C164, a cascadable 16 Kbit two-wire serial EEPROM. The file sits in the schematic category but is essentially part documentation with…
