BC547CBK

DIOTEC · Bipolar (BJT) · TO-92

BC547CBK from DIOTEC, in a TO-92. 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 C passive Collector of the NPN transistor; for the BC547 group, VCEO is 45 V, VCBO 50 V, dc collector current 100 mA with 200 mA peak, and Ptot 500 mW (valid with leads at ambient temperature 2 mm from the case).
2 B passive Base of the NPN transistor; peak base current is limited to 200 mA and the emitter-base voltage VEB0 is 5 V.
3 E passive Emitter of the NPN transistor; peak emitter current is limited to 200 mA and the emitter-base voltage VEB0 is 5 V.
