BC847B is a general-purpose NPN transistor produced by ROHM. It has BVCEO<45V(IC=1mA) and complements BC857B.
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.
| Collector‑emitter voltage (VCEO) max | 45 V |
|---|---|
| Typical DC current gain (hFE) at Ic = 1 mA | ≈280 |
The maximum collector‑emitter voltage is 45 V.
The typical DC current gain is about 280 at Ic = 1 mA.
