Shikues · Zener Diodes · SMB

1SMB5915BG from Shikues, in a SMB. 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 as pin 1 in the PINNING table (top view); the datasheet states no pin-specific electrical limits.
2 Anode passive Anode terminal of the Zener diode, identified as pin 2 in the PINNING table (top view); the datasheet states no pin-specific electrical limits.

CAD (KiCad official)

  • Symbol: 1SMB5915BG
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: 1smb5915bg-etched.step / 1smb5915bg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1smb5915bg.step / 1smb5915bg.glb are the bare package body.
