RLSD32A031V 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 | K | passive | Cathode (marked-band end) of the unidirectional TVS diode, connected to the protected I/O or power line, with 3.3V reverse stand-off voltage (VRWM) for RLSD32A031V. |
| 2 | A | passive | Anode of the unidirectional TVS diode, connected to ground/reference, protecting one line up to 300W peak pulse power (8/20μs). |
