Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

For the 2SK1905 N-channel field-effect transistor, this PDF of 92.7 KB is indexed under schematics, though a bare part number in the name points to a datasheet.

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

Short 31.7 KB PDF for the 2SK1460LS, an N-channel FET by the Japanese 2SK prefix, carrying an LS suffix that distinguishes it from the plain 2SK1460 also in this index.

Reference sheet for the 2SK937 transistor, a 79.9 KB PDF. Parts in the 2SK range are N-channel field-effect transistors under the Japanese JIS designation.

For the 2SJ579, this 42.7 KB PDF is indexed as a schematic, but a bare part-number name typically marks a datasheet.

Brief 24.7 KB PDF for the 2SJ0398, written with a leading zero in the name, which most likely refers to the 2SJ398 P-channel FET in JIS numbering.

Compact 39.7 KB PDF named 2sc4849, written in lowercase but following the Japanese JIS pattern where 2SC denotes an NPN transistor.

The 2SC3689 transistor is the subject of this 89.7 KB PDF, which the catalogue lists as a schematic.

Small 41.7 KB PDF for the 2SC5346; the _E suffix possibly marks an English edition, though the name alone cannot confirm this.

Component reference for the 2SB1297, delivered as a 41.7 KB PDF and listed under schematics.

Small 35.7 KB PDF for the 2SB1073; the _E suffix in the name is not explained and may mark a language edition or document version.

PDF reference for the 2SA1437, 77.6 KB, sorted into the schematic section. In the JIS system the 2SA prefix marks PNP transistors suited to high-frequency circuits.

Indexed as a schematic, this 72.3 KB PDF relates to the 2SB888, likely as its data sheet.

Reference sheet for the 2SA1346 in an 87.7 KB PDF. The name gives only the part number, so despite being indexed as a schematic it is most likely the device datasheet.

PDF datasheet for the 2N5401 PNP transistor, 75.2 KB, listed under schematics although it is a component document. No vendor or revision is given in the name.

The 1SV277 is documented in this 71.9 KB PDF, which the catalogue lists as a schematic.

Covering the 1SV263, this 64.7 KB PDF sits in the schematic category, though its name and size point to a single-component document.

Indexed under schematics, this 77.1 KB PDF is titled 1SV242 with a trailing underscore, and that is all the name reveals.

Filed among schematics, this 68.7 KB PDF bears the part number 1SS360 and no other information.

The name of this 71.4 KB PDF is simply 1SS314, a part number from the 1SS small-signal diode series defined under Japanese JIS designation and common in Toshiba product…

The file name provides just the part number 1SS307 for this 74.2 KB PDF, and no device context is given.

A 70.0 KB PDF categorised as a schematic but named solely after the part 1SS272, with no device, board number or revision.

PDF datasheet for the 1N5397 diode, 42.7 KB, catalogued under the schematic type although it describes one component.

Reference datasheet for the 1N4148 high-speed signal diode, stored as a 78.8 KB PDF in the schematic category.

Compact 80.7 KB PDF for the 189NQ135, a single Schottky rectifier designation in the NQ range; the 135 suffix most likely means a 135 V reverse rating.

A 92.7 KB PDF catalogued as a schematic, named 28C257, a code from the 28C series of parallel EEPROM memories. The name gives no vendor, speed grade or package.

Fairly large datasheet PDF of 705 KB named 25C16, catalogued as a schematic. The name follows the 25-series serial EEPROM convention, indicating a 16 Kbit SPI device…

PDF of 77.6 KB for the 24C01A, a 1 Kbit (128-byte) I2C serial EEPROM. The name carries only the part number with no device or board details, so expect general datasheet…
