BAT43W-E3-08 from Vishay Intertech, 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 terminal marked by the cathode bar on the SOD-123 body; repetitive peak reverse voltage is 30 V. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; forward continuous current is 200 mA maximum. |
