MM1W15 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 terminal of the MM1W15 zener diode (nominal Vz 15 V, 13.8 V min to 15.8 V max at IZT 17 mA), with the cathode end marked by the cathode line on the package. |
| 2 | A | passive | Anode terminal of the MM1W15 zener diode; the family forward voltage is 1.2 V at IF = 200 mA, and junction temperature is rated -55 to +150 ℃. |
