MMSZ8V2ET1G

onsemi · Zener Diodes · SOD-123

MMSZ8V2ET1G from onsemi, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the Zener diode. Indicated by the polarity band on the package. Reverse-bias current flows into this pin during Zener regulation at VZ = 8.2 V nominal.
2 A passive Anode of the Zener diode. Forward current flows into this pin (VF ≤ 0.9 V at IF = 10 mA); returns Zener current to circuit ground during reverse regulation.

CAD (KiCad official)

  • Symbol: MMSZ8V2ET1G
  • Footprint: Diode_SMD:D_SOD-123
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mmsz8v2et1g-etched.step / mmsz8v2et1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmsz8v2et1g.step / mmsz8v2et1g.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (7 pp, sha256 5b0b972b33dc1e88, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
