BCP55-10

Changjing · Bipolar (BJT) · SOT-223

BCP55-10 from Changjing, in a SOT-223. 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, rated for continuous base current of 100 mA and peak pulse base current of 200 mA.
2 COLLECTOR passive Collector terminal, rated for continuous collector current of 1 A and peak pulse collector current of 2 A, with collector power dissipation of 1.5 W.
3 EMITTER passive Emitter terminal, with emitter-base voltage rated at 5 V maximum.

CAD (KiCad official)

  • Symbol: BCP55-10
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: bcp55-10-etched.step / bcp55-10-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bcp55-10.step / bcp55-10.glb are the bare package body.
