DOWO · Diodes - General Purpose · SMA

1N4002 from DOWO, in a SMA. 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 Cathode passive Cathode terminal of the diode; polarity is indicated by the cathode band on the package.
2 Anode passive Anode terminal of the diode, opposite the cathode band.

CAD (KiCad official)

  • Symbol: 1N4002
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: 1n4002-etched.step / 1n4002-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1n4002.step / 1n4002.glb are the bare package body.
