PDF for the 2SB1292, 58.0 KB, bearing a _1-2 suffix that may mark a document part or revision without further explanation.

Brief 39.0 KB PDF on the 2SB1292 transistor, indexed as a schematic although it is a single-part reference.

Document for the 2SB1290 in PDF form, 57.9 KB, with a _1-2 suffix that possibly indicates a section or revision; the name does not say.

PDF of 105 KB for the 2SA1606, indexed among schematics yet covering a single semiconductor.

A PDF document for the 2SA1604, an 84 KB file listed in the index as a schematic but named after a single discrete part rather than a board.

Reference sheet in PDF form for the 2SA1593 transistor, 156 KB in size. The name gives only the part number, with no device or board details.

The 2SA1592 is covered by this 156 KB PDF, filed as a schematic although the name refers to a single semiconductor.

PDF datasheet-style file for the 2SB1290 transistor, only 38.7 KB, so likely a brief sheet of a few pages. The name carries no other details such as package or maker.

Component documentation for the 2SA1591, an 89.4 KB PDF. Only the part number appears in the name; no revision or manufacturer is given.

An 89.5 KB PDF for the 2SA1590 transistor, listed under schematics but almost certainly a part datasheet given the name.

Datasheet PDF covering the 2SA1588, 215 KB in size, which suggests several pages with curves and package details.

The 2SA1587 transistor is the subject of this 323 KB PDF, the largest in this group and likely to include detailed characteristic graphs.

PDF file of 231 KB for the 2SA1586, catalogued as a schematic but named after one discrete semiconductor.

Reference PDF, 88.0 KB, for the 2SA1582 transistor. The file name states only the part number and nothing about the maker, package or application.
