CMZ20

TOSHIBA · Zener Diodes · SOD-128

CMZ20 from TOSHIBA, in a SOD-128. 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 Anode passive Anode of the Zener diode; the CMZ20 has a Zener voltage of 18.0 to 22.0 V (20 V typ.) at the specified test current.
2 Cathode passive Cathode of the Zener diode, marked on the package with a cathode mark; power dissipation is rated at 2 W (Ta = 30°C, ceramic board).

CAD (KiCad official)

  • Symbol: CMZ20
  • Footprint: Diode_SMD:D_SOD-128
  • 3D model: SOD-128 (KiCad packages3D, STEP)
  • 3D model files: cmz20-etched.step / cmz20-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmz20.step / cmz20.glb are the bare package body.

Provenance

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

  • Datasheet: TOSHIBA datasheet (5 pp, sha256 692899659da6c4de, retrieved 2026-11-02, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
