1SMA5953BG from Shikues, 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, identified in the PINNING table and the simplified SMA outline and symbol; the datasheet states no additional electrical limits for this pin. |
| 2 | Anode | passive | Anode terminal of the Zener diode, identified in the PINNING table and the simplified SMA outline and symbol; the datasheet states no additional electrical limits for this pin. |
