MM1ZB18

HUXN · Zener Diodes · SOD-123

MM1ZB18 from HUXN, 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 MM1ZB18 Zener diode, which has a nominal Zener voltage of 18 V (17.64 to 18.36 V at 5 mA test current).
2 Anode passive Anode terminal of the MM1ZB18 Zener diode, used as the return side of the reverse-biased Zener clamp.

CAD (KiCad official)

  • Symbol: MM1ZB18
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1zb18-etched.step / mm1zb18-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1zb18.step / mm1zb18.glb are the bare package body.
