MM1W68

YFW · Zener Diodes · SOD-123

MM1W68 from YFW, in a SOD-123. 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 per the datasheet pinning (1.Cathode 2.Anode); the datasheet states no separate pin-level electrical limits for this terminal.
2 Anode passive Anode terminal of the Zener diode per the datasheet pinning (1.Cathode 2.Anode); the datasheet states no separate pin-level electrical limits for this terminal.

CAD (KiCad official)

  • Symbol: MM1W68
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1w68-etched.step / mm1w68-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1w68.step / mm1w68.glb are the bare package body.
