SMA2Z10A from YFW, in a SMA. 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 terminal of the zener diode; the polarity symbol marking on the body identifies this side. |
| 2 | Anode | passive | Anode terminal of the zener diode, opposite the cathode. |
