MM1W75 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 | CATHODE | passive | Cathode end, marked by the cathode line on the package; MM1W75 has a nominal Zener voltage of 75 V (71.2 V min to 78.8 V max) tested at IZT 3.3 mA, with maximum Zener impedance 175 Ω and maximum admissible Zener current 12 mA. |
| 2 | A | passive | Anode of the Zener diode; the datasheet gives a forward voltage of 1.2 V at IF = 200 mA, with reverse leakage IR of 1 µA at VR = 56 V. |
