BAT54W L4 from CBI, in a SOT-323. 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 | A | passive | Anode of the single Schottky diode (BAT54W, marking L4); the diode is rated for 30 V reverse voltage and 200 mA forward continuous current. |
| 2 | NC | unconnected | No internal connection on the single-diode BAT54W (L4); the pin is not wired in the schematic symbol. |
| 3 | K | passive | Cathode of the single Schottky diode (BAT54W, marking L4), on the top lead of the package symbol. |
