MM3Z24VT1G

onsemi · Zener Diodes · SOD-323

MM3Z24VT1G from onsemi, in a SOD-323. 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, indicated by the polarity band; connects to the positive side in reverse Zener operation, with VZ of 22.8 V min, 24.2 V nom, 25.6 V max at IZT = 5 mA for the MM3Z24VT1G.
2 A passive Anode; the forward voltage is 0.9 V max at IF = 10 mA, and the device dissipates 300 mW max steady state on FR-4.

CAD (KiCad official)

  • Symbol: MM3Z24VT1G
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: mm3z24vt1g-etched.step / mm3z24vt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm3z24vt1g.step / mm3z24vt1g.glb are the bare package body.
