RB521S30T1G-DW from DOWO, in a SOD-523. 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 end marked by the color band; reverse voltage VR is 30 V DC (VRM 30 V peak). |
| 2 | A | passive | Anode, the end opposite the color band; mean rectifying current Io is 0.2 A and peak forward surge IFSM is 1.0 A (8.3 ms half sine). |
