BC849BLT1G

onsemi · Bipolar (BJT) · SOT-23

BC849BLT1G from onsemi, 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 passive Base terminal of the NPN transistor; for the BC849 the datasheet limits are VEBO 5.0 V maximum and collector current IC 100 mA continuous.
2 EMITTER passive Emitter terminal of the NPN transistor; for the BC849 the datasheet limits are VCEO 30 V and VEBO 5.0 V maximum, with 100 mA continuous collector current.
3 COLLECTOR passive Collector terminal of the NPN transistor; for the BC849 the datasheet limits are VCEO 30 V and VCBO 30 V maximum, with 100 mA continuous collector current.

CAD (KiCad official)

  • Symbol: BC849BLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc849blt1g-etched.step / bc849blt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc849blt1g.step / bc849blt1g.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (14 pp, sha256 6048faac5fbfe6f2, retrieved 2026-10-13, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
