ROHM BC847B Transistor Datasheet
The BC847B is an NPN general‑purpose transistor with a collector‑emitter voltage rating of 45 V and a collector current capability up to 100 mA. It is offered in a compact SST3 (SOT‑23) package and is intended for a wide range of electronic circuit applications.
The document lists absolute maximum ratings, detailed electrical parameters such as VCEO, VCB0, VBE0, and hFE values, as well as characteristic curves for current gain, saturation voltage, and noise performance. An appendix contains usage notes and export control information. This manual is written in Chinese.
