1SMA5933A from LGE, in a DO-214AC(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 | K | passive | Cathode end, marked by the color band; for the 22 V 1SMA5933A it is the positive side in zener operation, with IZT 17.0 mA, ZZT 17.5 Ω and max DC zener current 68 mA. |
| 2 | A | passive | Anode end, opposite the color-banded cathode; forward voltage max 1.5 V at IF = 200 mA. |
