A 210 KB PDF for the 2SB905 transistor, part of a consecutive 2SB900-series group in this index. The 2SB prefix denotes a low-frequency PNP transistor under the Japanese JIS system. The file name gives no revision, maker or package details. Expect rating tables, typical performance graphs and an outline drawing. The pinout section is the key reference for bench testing with a diode-mode meter, and the limits help confirm that any replacement candidate is genuinely compatible.
