BC847BT

CBI · Bipolar (BJT) · SOT-523

BC847BT from CBI, in a SOT-523. 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 B input Base of the NPN transistor; VEBO max is 6 V for BC847T and VBE(on) is 580 mV min to 700 mV max at VCE = 5 V, IC = 2 mA.
2 E passive Emitter of the NPN transistor, the common return for collector current, with collector current IC rated at 100 mA continuous and 200 mA peak.
3 C passive Collector of the NPN transistor; VCEO max is 45 V and VCBO max is 50 V for BC847T, with IC of 100 mA continuous.

CAD (KiCad official)

  • Symbol: BC847BT
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: bc847bt-etched.step / bc847bt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc847bt.step / bc847bt.glb are the bare package body.
