1SMA5929B

YFW · Zener Diodes · SMA

1SMA5929B from YFW, 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 gives the pinning as 1 = Cathode, 2 = Anode for the DO-214AC/SMA package.
2 Anode passive Anode terminal of the Zener diode; the datasheet gives the pinning as 1 = Cathode, 2 = Anode for the DO-214AC/SMA package.

CAD (KiCad official)

  • Symbol: 1SMA5929B
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: 1sma5929b-etched.step / 1sma5929b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma5929b.step / 1sma5929b.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
