**Changjing** · Schottky Diodes · SOT-323

RB461F 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 | A | passive | Anode of the Schottky diode, with forward voltage max 0.49 V at IF=700 mA and average rectified current IO of 700 mA. |
| 2 | NC | unconnected | Not connected internally; shown as an open terminal with no diode connection in the package schematic. |
| 3 | K | passive | Cathode of the Schottky diode, with DC blocking voltage VR of 20 V and reverse leakage max 200 µA at VR=20 V. |

## CAD (KiCad official)

- Symbol: `RB461F`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323 (KiCad packages3D, STEP)
- 3D model files: `rb461f-etched.step` / `rb461f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rb461f.step` / `rb461f.glb` are the bare package body.
