PDF document of 246 KB tied to the 1N4001 rectifier, catalogued under schematics. The plus sign in the name is uninformative and does not identify a vendor or revision…

A 135 KB PDF listed as a schematic for the 201CNQ series, a family of high-current Schottky rectifier modules.

The name 151cmq carries no board or equipment model, only a component code, so this 44.3 KB PDF is likely a datasheet for a common-cathode Schottky rectifier family…

PDF of 97.8 KB for the 40EPF-HV, filed as a schematic though it is component documentation.

PDF diagram covering the power-on (encendido, Spanish for switching on) circuit of the G532 phone, the Samsung J2 Prime / Grand Prime Plus family.

Samsung troubleshooting guide for the Galaxy J7 model SM-J700H in PDF. TSHOO documents in Samsung service material normally cover fault-finding procedures with block…

PDF schematic for board BM5070, a code that other files in this index link to the Lenovo Legion S7-15ACH6 AMD laptop, although this name gives no model.

Datasheet-type document for the 3N251 in a 43.6 KB PDF, indexed as a schematic. JEDEC uses the 3N prefix for registered four-terminal semiconductor devices, and this…

Indexed as a schematic, this 50.3 KB PDF is titled 1N757A, a JEDEC 1N diode number with A suffix, so it almost certainly holds a part datasheet.

A 53.6 KB PDF listed as a schematic, named 153cnq080; the code corresponds to a dual Schottky rectifier, and the 080 suffix generally indicates an 80 V reverse rating.

A 107 KB PDF named for the 1BQ series, listed as a schematic but most likely a datasheet for a family of small Schottky or rectifier diodes sharing that prefix.

Named 401CNQ and filed as a schematic, this 160 KB PDF gives no brand, model or board revision.

Named simply 50SQ, the 132 KB PDF in the schematic category covers what looks like a component family rather than a specific device; no brand, model or board is given.

Indexed as a schematic, this PDF of about 187 KB is named 8ETH06. In International Rectifier and Vishay numbering the ETH family is a hyperfast rectifier line, so the…

PDF schematic labelled SL410K, a model name that matches the Lenovo ThinkPad SL410 family, although no brand is stated in the file name.

Samsung SM-J110H troubleshooting manual, apparently revision 7-1, provided as a 13.7 MB PDF.

Schematic in PDF format for the Jetway 845GDM motherboard, approximately 669 KB, without a revision number in the file name.

Schematic PDF of 4.74 MB for the W670RCQ, with ESM in the name; the brand is not stated, though W-series codes of this type are associated with Clevo-designed laptops…

Small 42.2 KB PDF filed as a schematic for the 3N256 part. Under the JEDEC system the 3N prefix marks a registered device with four leads, and the same size across 3N253…

Document for the 2SK2841, a JIS-style part number whose 2SK prefix marks an N-channel FET.

Component documentation for the 2SA1314 in PDF format, 162 KB. The type field says schematic, but the name consists only of the part code, which normally means a…

Glass passivated 1N4935GP fast recovery rectifier datasheet, a 45.7 KB PDF in the schematic section.

A 144 KB PDF filed under schematics for the 220CNQ030, a designation that matches the CNQ family of high-current Schottky rectifier modules.

A 48.5 KB PDF in the schematic category, named 75SLQ045. The name carries no model, brand or board number and resembles a discrete power semiconductor part code, likely…

This 50.1 KB PDF, labelled 30SCLJQ030 and catalogued as a schematic, most likely documents one discrete rectifier rather than a circuit board, based on its part-number…

Titled 25CXXX, this 160 KB PDF uses a placeholder in its name, which typically signals a family datasheet covering several capacities of one memory or chip series.

Filed as a schematic, this PDF of roughly 100 KB is named 10CTQ150L. The CTQ code in International Rectifier and Vishay numbering identifies a common-cathode dual…
