RB411D from Changjing, in a SOT-23. 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 | A | passive | Anode of the Schottky diode, per the internal diagram on page 1 (forward voltage max 0.5 V at IF=500 mA, mean rectified output current 500 mA). |
| 2 | NC | unconnected | No internal connection; shown as an unconnected open terminal in the page 1 diagram. |
| 3 | K | passive | Cathode of the Schottky diode, per the internal diagram on page 1 (DC reverse voltage 20 V, peak repetitive reverse voltage 40 V, reverse current max 30 µA at VR=10 V). |
