Datasheet-style PDF, 201 KB, for the 2SB908 transistor. Japanese JIS numbering uses 2SB for PNP transistors intended for low-frequency service, which commonly means audio output, regulator pass or driver roles. The name provides no revision or package detail. Consult the absolute maximum ratings, hFE grades and outline drawing when testing or replacing the part. Power devices like this often fail shorted, so check the surrounding resistors and the driving stage as well, and confirm the pin order before fitting any substitute.
