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…

Datasheet PDF for the BD234, only 49.2 KB and indexed as a schematic. The BD234 is a medium-power PNP transistor in a plastic package, commonly paired with a…

Reference PDF of 40.9 KB for the 2SD1819A, with an E tag in the name that probably denotes an English-language edition, filed under schematics.

PDF of 140 KB for the 2SK2739 with an unexplained 1-5 suffix, which may indicate an edition or page count rather than a different part.

Datasheet-style PDF of 139 KB for the 2SK2460N, listed in the schematic category. Under Japanese JIS numbering a 2SK prefix marks an N-channel field-effect transistor…

A 105 KB PDF for the 2SJ421, catalogued as a schematic but in practice a component datasheet, since the 2SJ prefix in the Japanese JIS numbering system marks a P-channel…

Short 125 KB PDF on the 2SC5086FT, the FT-suffixed variant of the 2SC5086 NPN transistor; the name does not say what the suffix means, though such suffixes usually mark…

The 2SC4071 is the subject of this 47.7 KB PDF, which sits in the schematic category although the name suggests a single-component datasheet.

A 40.9 KB PDF for the 2SC5303, a JIS-registered NPN transistor, catalogued here as a schematic although it reads as a part datasheet.

A 58.1 KB PDF labelled as a schematic and named after the 2SC1215, an NPN transistor by Japanese JIS naming, so it should be the datasheet for that discrete part.

Small 20.5 KB PDF named for 2N5551 with a UTC tag, which most likely refers to the manufacturer that published this version.

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…

Component datasheet in PDF form for the 2N5458, an N-channel junction FET usually found in TO-92 packages, catalogued here as a schematic-type document of about 130 KB.

Two part numbers appear in the name, 1N914 and 1N916, so this 78.8 KB PDF is a shared datasheet for two related JEDEC 1N diodes rather than a board schematic.

Reference PDF of 142 KB for the 220CMQ030, a CMQ-series part closely related to the CNQ Schottky modules, likely differing in package or mounting style.

PDF of 139 KB, listed as a schematic with the code 70epf02. The name carries no laptop model, board number or revision, so the subject must be confirmed by reading the…

A small 38.8 KB PDF titled 30WQ09F, catalogued among schematics but most plausibly a datasheet for a discrete rectifier, judging by the part-number style.

The file 30WQ03F is a 38.7 KB PDF that, despite its schematic label, appears to be a datasheet for a single rectifier diode, judging from the naming.

The Microchip 24LC32A, a 32 Kbit I2C serial EEPROM, is documented in this 586 KB PDF that the index lists as a schematic, though it reads as a datasheet.
