RB706F-40 from Changjing, in a SOT-323. 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 the first Schottky diode, whose cathode connects to common pin 3; the diode is rated 40 V DC reverse voltage (45 V peak) and 30 mA mean rectifying current. |
| 2 | K2 | passive | Cathode of the second Schottky diode, whose anode connects to common pin 3; the diode is rated 40 V DC reverse voltage and 30 mA mean rectifying current. |
| 3 | COM | passive | Common node joining the cathode of the first diode and the anode of the second diode (series configuration); the device is rated at 200 mW power dissipation. |
