LBC847BWT1G

LRC · Bipolar (BJT) · SC-70

LBC847BWT1G from LRC, in a SC-70. 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 general-purpose transistor; the datasheet gives no pin-specific limits, and the LBC847 series maximum ratings are V(CEO) 45 V, V(CBO) 50 V, V(EBO) 6.0 V and continuous I(C) 100 mAdc.
2 EMITTER passive Emitter terminal of the NPN general-purpose transistor; the datasheet gives no pin-specific limits, and the LBC847 series maximum ratings are listed as device-level values only.
3 COLLECTOR passive Collector terminal of the NPN general-purpose transistor; the datasheet gives no pin-specific limits, and total device dissipation is 150 mW with junction-to-ambient thermal resistance of 833 °C/W.

CAD (KiCad official)

  • Symbol: LBC847BWT1G
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SC-70 (KiCad packages3D, STEP)
  • 3D model files: lbc847bwt1g-etched.step / lbc847bwt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lbc847bwt1g.step / lbc847bwt1g.glb are the bare package body.
