RLSD32A051C from RUILON Shenzhen Ruilongyuan Elec, in a SOD-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 | Bidirectional TVS terminal 1 (VRWM 5V, VBR min 6V @1mA, VC 12V @IPP 30A at 8/20μs, IR 1μA max at VRWM); protects one I/O or power line and is interchangeable with the other terminal. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (VRWM 5V, VBR min 6V @1mA, VC 12V @IPP 30A at 8/20μs, IR 1μA max at VRWM); protects one I/O or power line and is interchangeable with the other terminal. |
