B772-Y

FUXINSEMI · Bipolar (BJT) · SOT-89

B772-Y from FUXINSEMI, in a SOT-89. 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 of the PNP transistor; emitter-base voltage limit is -6 V and collector current is rated up to -3 A continuous.
2 COLLECTOR passive Collector of the PNP transistor (also the tab); VCBO -40 V, VCEO -30 V, IC -3 A continuous, power dissipation 0.5 W.
3 EMITTER passive Emitter of the PNP transistor; emitter-base breakdown voltage is -6 V minimum at IE=-100 µA.

CAD (KiCad official)

  • Symbol: B772-Y
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: b772-y-etched.step / b772-y-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b772-y.step / b772-y.glb are the bare package body.
