MM1Z27

hongjiacheng · Zener Diodes · SOD-123

MM1Z27 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's reverse breakdown VZ for MM1Z27 is 27V nominal (25.1V to 28.9V) at IZT=5mA.
2 A passive Anode terminal of the zener diode; forward voltage VF is 0.9V at IF=10mA.

CAD (KiCad official)

  • Symbol: MM1Z27
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1z27-etched.step / mm1z27-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1z27.step / mm1z27.glb are the bare package body.
