MMSZ10VCW from YONGYUTAI, 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 color-band end; the Zener voltage is 10 V nominal (9.4 V min to 10.6 V max) at Izt = 5 mA, with maximum reverse current 0.2 uA at VR = 7.0 V. |
| 2 | A | passive | Anode, the end opposite the color band; forward voltage is 0.9 V at IF = 10 mA and power dissipation is 500 mW maximum. |
