BC847A RFG

Taiwan Semiconductor(Taiwan Semicon) · Bipolar Transistors - BJT · SOT-23

BC847A RFG from Taiwan Semiconductor(Taiwan 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 Base input Base terminal of the NPN transistor; for BC847 the emitter-base breakdown voltage is 6 V min and the emitter-base voltage rating is 6 V.
2 Emitter passive Emitter terminal of the NPN transistor, the reference for the VCEO of 45 V and VEBO of 6 V ratings of the BC847.
3 Collector passive Collector terminal of the NPN transistor; BC847 collector current is rated 0.1 A, VCEO 45 V, VCBO 50 V, and power dissipation 200 mW.

CAD (KiCad official)

  • Symbol: BC847A RFG
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc847a-rfg-etched.step / bc847a-rfg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc847a-rfg.step / bc847a-rfg.glb are the bare package body.
