1SMA5928BT3G

onsemi · Zener Diodes · SMA

1SMA5928BT3G from onsemi, 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, marked by the molded polarity notch or cathode band on the package (STYLE 1 polarity band).
2 ANODE passive Anode terminal of the Zener diode, opposite the cathode polarity band.

CAD (KiCad official)

  • Symbol: 1SMA5928BT3G
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: 1sma5928bt3g-etched.step / 1sma5928bt3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma5928bt3g.step / 1sma5928bt3g.glb are the bare package body.
