B0530WS SE from Changjing, 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 of the Schottky barrier diode, the banded end of the SOD-323 package; the datasheet gives VRRM/VRWM/VR of 30 V for the B0530WS. |
| 2 | A | passive | Anode of the Schottky barrier diode; the datasheet gives average rectified output current Io of 0.5 A and forward voltage of 0.45 V at IF=0.5A (typ. column) for the B0530WS. |
