RB411DT146 from ROHM Semicon, 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 | NC | unconnected | Not connected internally; the Structure drawing shows this lead with no connection to the diode. |
| 2 | A | passive | Anode of the single Schottky diode; reverse voltage 20 V DC (40 V repetitive peak), average rectified forward current 500 mA, VF max 0.50 V at IF=500 mA. |
| 3 | K | passive | Cathode of the single Schottky diode; reverse voltage 20 V DC (40 V repetitive peak), IR max 30 uA at VR=10 V. |
