MMSZ5246B-TP

MCC Micro Commercial Components · Zener Diodes · SOD-123

MMSZ5246B-TP from MCC Micro Commercial Components, 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, the end marked with the cathode band; it goes positive of the anode in zener operation, with VZ = 16V nominal at IZT = 7.8mA for the MMSZ5246B.
2 A passive Anode, the end opposite the cathode mark; forward voltage is at most 0.9V at IF = 10mA.

CAD (KiCad official)

  • Symbol: MMSZ5246B-TP
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mmsz5246b-tp-etched.step / mmsz5246b-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmsz5246b-tp.step / mmsz5246b-tp.glb are the bare package body.
