BC847 1F

Changjing · Bipolar (BJT) · SOT-23

BC847 1F from Changjing, 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 BASE input BASE terminal of the NPN transistor; the datasheet's absolute maximum ratings give VEBO 6 V and continuous collector current IC 0.1 A for the device.
2 EMITTER passive EMITTER terminal of the NPN transistor; the datasheet gives no pin-specific limit, and the device ratings are VCEO 45 V for BC847 and PC 200 mW.
3 COLLECTOR passive COLLECTOR terminal of the NPN transistor; for BC847 the datasheet gives VCBO 50 V and VCEO 45 V, with PC 200 mW total dissipation.
