PXT2222A

Changjing · Bipolar (BJT) · SOT-89-3L

PXT2222A from Changjing, in a SOT-89-3L. 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, driven to control collector current; the datasheet rates the emitter-base voltage VEBO at 6 V.
2 COLLECTOR passive Collector terminal, rated for VCBO 75 V, VCEO 40 V, continuous collector current IC 600 mA and collector power dissipation PC 0.5 W.
3 EMITTER passive Emitter terminal, with emitter-base breakdown voltage V(BR)EBO of 6 V and the same 6 V VEBO rating as the base-emitter limit.

CAD (KiCad official)

  • Symbol: PXT2222A
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3L (KiCad packages3D, STEP)
  • 3D model files: pxt2222a-etched.step / pxt2222a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pxt2222a.step / pxt2222a.glb are the bare package body.
