Datasheet-style document, 133 KB in PDF format, covering the 2SD1681 part number and listed as a schematic.

Part documentation for the 2SK2731, a 113 KB PDF placed in the schematic category. JIS naming assigns the 2SK prefix to N-channel field-effect transistors, so the…

Small 23.4 KB PDF for the 2SK2660 transistor. The 2SK designation comes from the Japanese JIS system for N-channel FETs, so the file is most likely a brief datasheet…

Very small 32.3 KB PDF titled 2SK2383, listed in the schematic category but most probably a short datasheet or summary sheet for an N-channel field-effect transistor, as…

PDF of 98.9 KB for the 2SK1898, listed under schematics but in practice a component reference for one transistor.

Compact 31.0 KB PDF for the 2SK662, a JIS-registered N-channel field-effect transistor number, most likely the manufacturer datasheet despite its schematic label.

Listed as a schematic, this 31.1 KB PDF is named for the 2SJ594, a format typical of an individual component datasheet.

Datasheet document, by all indications, for the 2SJ189, a JIS-registered P-channel FET, held as an 83.5 KB PDF in the schematic section.

A 196 KB PDF named for the 2SC4684 and listed in the schematic category. Its 2SC prefix is the JIS marker for NPN bipolar transistors, so the document is best read as a…

Larger than most in this series at 254 KB, this PDF documents the 2SC4497 NPN bipolar transistor, the 2SC prefix being the JIS designation.

Transistor 2SC4458 is the subject of this 103 KB PDF, which the catalogue lists as a schematic.

The 2SC4423 is described by this 102 KB PDF, which the index lists as a schematic. Since 2SC is the JIS prefix for NPN bipolar transistors, the contents should be a…

At just 39.2 KB, the PDF named 2SC4291 is a compact document filed as a schematic, though the name suggests a brief transistor datasheet.

Datasheet-style PDF of 158 KB for the 2SC5765, indexed in the schematics section. Beyond the part number the name is uninformative; the 2SC prefix denotes an NPN…

For the 2SC5439 transistor, this 192 KB PDF is most likely a manufacturer datasheet, given that 2SC is the JIS designation for NPN bipolar parts.

A 467 KB PDF covering the 2SC5066, listed as a schematic but named after a JIS-designated NPN bipolar transistor, so expect a datasheet with ratings, curves and package…

Covering the 2SC5416LS, this 43.0 KB PDF is the LS variant of the 2SC5416, which is documented in a companion file.

A 320 KB PDF named for the 2SC3329, listed under schematics though it is most probably a full transistor datasheet.

Part 2SC3070 is the subject of this 91.1 KB PDF, listed among schematics. No manufacturer, package or gain grade appears in the name.

At 160 KB, this PDF for the 2SB1667 is larger than the other 2SB166x and 167x sheets, perhaps containing more curves or pages.

The 2SB1406 transistor is the subject of this 70.7 KB PDF, listed under schematics but best treated as a datasheet. No other information is encoded in the name.
