KB5819WS from KUU, in a SOD-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 | K | passive | Cathode (marked "−" on the package drawing, symbol's bar side); the KB5819WS blocks 40 V VRRM/VR and carries 1 A average rectified output current. |
| 2 | A | passive | Anode (marked "+" on the package drawing, symbol's triangle side); forward voltage is 0.6 V max at IF=1 A and 0.9 V max at IF=3 A for the KB5819WS. |
