PDF datasheet for the 2SB1594 transistor, about 187 KB, indexed as a schematic. In JIS numbering 2SB marks a PNP bipolar transistor for low-frequency applications; the name provides no vendor, package or revision. The document supports component-level repair by listing absolute maximum ratings, typical characteristics and outline dimensions with lead order. Before fitting a replacement, compare the marking on the original, check polarity and package, and make sure voltage and current ratings meet or exceed those of the part removed.
