BC547-B

Foshan Blue Rocket Elec · Bipolar (BJT) · TO-92-3

BC547-B from Foshan Blue Rocket Elec, in a TO-92-3. 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 NPN transistor; the datasheet limits continuous emitter current to -100 mA and emitter-to-base voltage VEBO to 6.0 V.
2 Base passive Base terminal of the NPN transistor; the datasheet gives VBE(sat) of 0.9 V (typ) to 1.1 V (max) at IC=100 mA, IB=5.0 mA.
3 Collector passive Collector terminal of the NPN transistor; the datasheet limits VCBO to 50 V, VCEO to 45 V, continuous IC to 100 mA and collector power dissipation PC to 625 mW.
