RB521S30T1G from onsemi, 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, identified by the polarity band on the SOD-523 package; the device is rated for a reverse voltage VR of 30 Vdc and a forward DC current IF of 200 mA. |
| 2 | ANODE | passive | Anode terminal, opposite the polarity-band cathode; the device has a maximum forward voltage of 0.50 Vdc at IF = 200 mA. |
