1SMA5923A

LGE · Zener Diodes · DO-214AC(SMA)

1SMA5923A from LGE, in a DO-214AC(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 K passive Cathode, the end marked with a color band; the Zener diode is operated reverse-biased with this pin positive relative to the anode.
2 A passive Anode, the end opposite the color band; maximum forward voltage is 1.5 V at IF = 200 mA.

CAD (KiCad official)

  • Symbol: 1SMA5923A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: 1sma5923a-etched.step / 1sma5923a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma5923a.step / 1sma5923a.glb are the bare package body.
