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.
