S1W from LGE, in a SMA(DO-214AC). 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, marked by the cathode band on the SMA/DO-214AC body; S1W is a rectifier with 1.0 A average forward current (I(AV)) and 1.1 V maximum forward voltage at 1.0 A. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; the datasheet rates the S1 series for peak forward surge current of 30 A (8.3 ms half sine-wave). |
