Compact 45.3 KB PDF for the 2SA1207, listed as a schematic, though the name offers only the part number, which suggests a datasheet.

The 2SA1891 PNP transistor is the subject of this 129 KB PDF, named only by its JIS part number.

Covering the 2SA1837, this 173 KB PDF is listed as a schematic but is expected to be a transistor datasheet.

PDF reference for the 2SA1807 transistor, 43.9 KB, listed as a schematic but in practice a component datasheet.

Component documentation for the 2N7222, a 227 KB PDF filed under schematics; the 2N prefix indicates a registered discrete semiconductor, so expect a datasheet rather…

A 255 KB PDF for the 2N4918, tagged RE in the name, possibly a revised or alternate edition though this is not defined.

Small 45.8 KB PDF dedicated to the 2N3866, sorted into the schematic section of the index though the name indicates a discrete component datasheet.

PDF datasheet for the 2N3055 at 236 KB, catalogued as a schematic; the a1 ending in the name is not defined and could be a vendor document code or revision.

This 47.8 KB PDF is labelled 1T379 and catalogued as a schematic. No device model, manufacturer or revision appears in the name.

The 1SV287 part is covered by this 75.6 KB PDF, filed under schematics. Its 1SV numbering identifies a varactor diode, so the content is most likely a datasheet rather…

Reference PDF for the 1SV285, about 70.4 KB, catalogued as a schematic. The 1SV prefix marks a variable-capacitance diode, so this should be a manufacturer data sheet.

Specification sheet for the 1SV284 part in PDF format, 69.8 KB, listed in the schematic category.

Datasheet-style PDF for the 1SS385F, 68.1 KB, filed under schematics. The trailing F is part of the part number and may indicate a package or variant of the 1SS385, so…

Brief 45.2 KB PDF covering the 183NQ series, a Schottky rectifier family whose name lacks a voltage suffix, so several grades are probably tabulated together.

Catalogued as a schematic, this 155 KB PDF named 1F1-1F7 indicates a numbered component series, most plausibly rectifier diodes in steps of reverse voltage.

Short PDF of 130 KB named 274002, a bare number that gives no device, brand or part information.
