PDF of 176 KB for the 2SD2384, an NPN bipolar transistor going by its JIS 2SD prefix, filed as a schematic in this index. The file name carries only the part number, with no manufacturer, package or version. A datasheet like this normally sets out absolute maximum ratings, electrical characteristics and dimensions. Use it to identify the base, collector and emitter, test for shorted junctions and compare limits before substituting another device.
