MM3Z8V2BW

Tak Cheong · Zener Diodes · SOD-323

MM3Z8V2BW from Tak Cheong, 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 of the zener diode (marked by the band); MM3Z8V2BW has VZ 8.04 V min, 8.2 V nom, 8.36 V max at IZT = 5 mA.
2 A passive Anode of the zener diode; device power dissipation is limited to 200 mW at TA = 25°C.

CAD (KiCad official)

  • Symbol: MM3Z8V2BW
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: mm3z8v2bw-etched.step / mm3z8v2bw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm3z8v2bw.step / mm3z8v2bw.glb are the bare package body.
