RB521S-30 from TWGMC, 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 | Cathode | passive | Cathode terminal of the Schottky barrier diode; the datasheet pinning lists pin 1 as cathode. |
| 2 | Anode | passive | Anode terminal of the Schottky barrier diode; the datasheet pinning lists pin 2 as anode. |
