B5819W-G from Changjing, 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 lead marked with the bar (shown as "−") on the package; B5819W-class diode has VRRM 40 V and IO 1 A. |
| 2 | A | passive | Anode, the lead opposite the cathode bar (shown as "+") on the package; forward current up to 1 A average (IFRM 1.5 A, IFSM 9 A). |
