PANJIT International · Zener Diodes · SMA(DO-214AC)

1SMA4753 from PANJIT International, in a SMA(DO-214AC). 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, identified by the color band at the cathode end of the DO-214AC (SMA) package.
2 Anode passive Anode terminal, at the end of the DO-214AC (SMA) package opposite the color-band cathode end.

CAD (KiCad official)

  • Symbol: 1SMA4753
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: 1sma4753-etched.step / 1sma4753-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma4753.step / 1sma4753.glb are the bare package body.
