2SC5712

TOSHIBA · Bipolar (BJT) · SOT-89

2SC5712 from TOSHIBA, 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 B input Base; drive input, with VEBO max 7 V and IB max 0.3 A.
2 C passive Collector (also the heat sink tab); VCBO 100 V, VCEO 50 V, IC 3.0 A DC and 5.0 A pulse.
3 E passive Emitter; common current return of the NPN transistor.

CAD (KiCad official)

  • Symbol: 2SC5712
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: 2sc5712-etched.step / 2sc5712-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sc5712.step / 2sc5712.glb are the bare package body.
