MM1Z30B

hongjiacheng · Zener Diodes · SOD-123

MM1Z30B from hongjiacheng, 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 K passive Cathode, marked by the cathode line on the package; the Zener diode (MM1Z30B: VZ 29.4-30.6 V at IZT 5 mA) conducts in reverse from this pin to pin 2.
2 A passive Anode of the Zener diode; forward voltage VF is 0.9 V at IF=10 mA, and power dissipation is limited to 500 mW.

CAD (KiCad official)

  • Symbol: MM1Z30B
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1z30b-etched.step / mm1z30b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1z30b.step / mm1z30b.glb are the bare package body.
