BFS520-C

Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-323

BFS520-C from Slkor SLKORMICRO Elec, in a SOT-323. 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 B input Base terminal of the NPN transistor; the datasheet gives no separate base limit, and base-emitter reverse leakage IEBO is 0.1 µA max at VEB=1 V.
2 E passive Emitter terminal of the NPN transistor; emitter-base breakdown voltage VEBO is 2 V (absolute maximum rating at TA=25℃).
3 C passive Collector terminal of the NPN transistor; limits are VCBO 20 V, VCEO 12 V and collector current IC 100 mA (absolute maximum ratings at TA=25℃).

CAD (KiCad official)

  • Symbol: BFS520-C
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: bfs520-c-etched.step / bfs520-c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bfs520-c.step / bfs520-c.glb are the bare package body.
