MM1Z3V0 from hongjiacheng, 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, the end marked by the cathode line on the SOD-123 body; the zener voltage for MM1Z3V0 is 2.8 V min, 3.0 V nom and 3.2 V max at IZT = 5 mA. |
| 2 | A | passive | Anode, the end opposite the cathode line; the forward voltage is 0.9 V at IF = 10 mA and power dissipation is 500 mW. |
