2SA1012B

Changjing · Bipolar (BJT) · TO-252-2L

2SA1012B from Changjing, in a TO-252-2L. 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 2SA1012B PNP transistor; the datasheet gives no separate pin-level limit, and the emitter-base voltage VEBO is rated -6 V.
2 COLLECTOR passive Collector terminal of the 2SA1012B PNP transistor, with absolute maximum ratings of VCBO -50 V and collector current IC -2 A.
3 EMITTER passive Emitter terminal of the 2SA1012B PNP transistor, with emitter-base voltage VEBO limited to -6 V.

CAD (KiCad official)

  • Symbol: 2SA1012B
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2L (KiCad packages3D, STEP)
  • 3D model files: 2sa1012b-etched.step / 2sa1012b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sa1012b.step / 2sa1012b.glb are the bare package body.
