RB705DT146 from ROHM Semicon, in a TO-236-3(SOT-23-3). 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 | A1 | passive | Anode of one Schottky diode (VR 40 V, Io 30 mA per diode, IFSM 0.2 A). |
| 2 | A2 | passive | Anode of the second Schottky diode (VR 40 V, Io 30 mA per diode, IFSM 0.2 A). |
| 3 | K | passive | Common cathode of both Schottky diodes (VR 40 V, VF max 0.37 V at IF=1 mA). |
