1SMA5953BG

Shikues · Zener Diodes · SMA

1SMA5953BG 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, identified in the PINNING table and the simplified SMA outline and symbol; the datasheet states no additional electrical limits for this pin.
2 Anode passive Anode terminal of the Zener diode, identified in the PINNING table and the simplified SMA outline and symbol; the datasheet states no additional electrical limits for this pin.

CAD (KiCad official)

  • Symbol: 1SMA5953BG
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: 1sma5953bg-etched.step / 1sma5953bg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma5953bg.step / 1sma5953bg.glb are the bare package body.
