BC846BM3T5G

onsemi · Bipolar (BJT) · SOT-723

BC846BM3T5G from onsemi, in a SOT-723. 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 gives an emitter-base voltage rating VEBO of 6.0 Vdc maximum and a base-emitter saturation voltage VBE(sat) of 0.7 V to 0.9 V at IC = 10 mA to 100 mA.
2 EMITTER passive Emitter terminal of the NPN transistor; the datasheet gives an emitter-base breakdown voltage V(BR)EBO of 6.0 V minimum and an emitter-base voltage rating VEBO of 6.0 Vdc maximum.
3 COLLECTOR passive Collector terminal of the NPN transistor; the datasheet gives a collector-emitter voltage VCEO of 65 Vdc, a collector-base voltage VCBO of 80 Vdc, and a continuous collector current IC of 100 mAdc maximum.

CAD (KiCad official)

  • Symbol: BC846BM3T5G
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 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: bc846bm3t5g-etched.step / bc846bm3t5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc846bm3t5g.step / bc846bm3t5g.glb are the bare package body.
