1SMA4746AG

Shikues · Zener Diodes · SMA

1SMA4746AG from Shikues, 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 zener diode; the datasheet's PINNING table identifies it only as Cathode and gives no further pin-specific limits.
2 Anode passive Anode terminal of the zener diode; the datasheet's PINNING table identifies it only as Anode and gives no further pin-specific limits.

CAD (KiCad official)

  • Symbol: 1SMA4746AG
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: 1sma4746ag-etched.step / 1sma4746ag-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma4746ag.step / 1sma4746ag.glb are the bare package body.
