MM3Z12VCW
YONGYUTAI · Zener Diodes · SOD-323
MM3Z12VCW from YONGYUTAI, 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, the end marked by the color band; for the MM3Z12VCW the Zener voltage is 12 V nominal (11.4 V to 12.7 V at Izt = 5 mA). |
| 2 | A | passive | Anode, the end opposite the color band; forward voltage is 0.9 V at IF = 10 mA and power dissipation is limited to 200 mW. |
