BC847-C-RTK
KEC Semicon · Bipolar (BJT) · SOT-23
BC847-C-RTK from KEC Semicon, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EMITTER | passive | Emitter terminal of the transistor; the datasheet rates the emitter current at -100 mA (IE) for this device family. |
| 2 | BASE | input | Base terminal of the transistor; the datasheet rates the base current at 20 mA (IB) for this device family. |
| 3 | COLLECTOR | passive | Collector terminal of the transistor; the datasheet rates DC collector current at 100 mA (pulse 200 mA) and BC847 collector-emitter voltage VCEO at 45 V. |
