BCX19LT1G

onsemi · Bipolar (BJT) · SOT-23

BCX19LT1G 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 general-purpose transistor (BCX19LT1G); the datasheet gives an emitter-base voltage limit VEBO of 5.0 Vdc.
2 EMITTER passive Emitter terminal of the NPN transistor; the datasheet's emitter-base voltage limit VEBO is 5.0 Vdc and the absolute maximum collector current is 500 mAdc continuous.
3 COLLECTOR passive Collector terminal of the BCX19LT1G; the datasheet gives a collector-emitter voltage VCEO of 45 Vdc, collector-base voltage VCBO of 50 Vdc, and continuous collector current IC of 500 mAdc.

CAD (KiCad official)

  • Symbol: BCX19LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bcx19lt1g-etched.step / bcx19lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bcx19lt1g.step / bcx19lt1g.glb are the bare package body.
