2SC3303

Changjing · Bipolar (BJT) · TO-252-2(DPAK)

2SC3303 from Changjing, in a TO-252-2(DPAK). 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 NPN base terminal; the datasheet gives VBE(sat) of 1.2 V at IC=3 A, IB=150 mA and the emitter-base rating VEBO of 7 V.
2 COLLECTOR passive NPN collector terminal; the absolute maximum ratings are VCBO 100 V, VCEO 80 V, IC 5 A and PC 1 W, with Tj 150 °C.
3 EMITTER passive NPN emitter terminal; the datasheet gives the emitter-base breakdown voltage V(BR)EBO of 7 V minimum at IE=100 µA.

CAD (KiCad official)

  • Symbol: 2SC3303
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)
  • 3D model files: 2sc3303-etched.step / 2sc3303-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sc3303.step / 2sc3303.glb are the bare package body.
