MM1Z11 from FOSAN, 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 (marked − in the internal configuration diagram); the zener regulates at VZ = 11 V nominal (10.4-11.6 V at IZT = 5 mA) when reverse-biased, with a 500 mW power dissipation limit. |
| 2 | A | passive | Anode (marked + in the internal configuration diagram); forward voltage is 0.9 V max at IF = 10 mA. |
