RLSD92Q051LV from RUILON(Shenzhen Ruilongyuan Elec), in a SOD-882. 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 | CATHODE | passive | Cathode of the unidirectional TVS/ESD protection diode (VRWM 5 V), protecting the one line it is connected to against ESD (IEC61000-4-2 ±8 kV contact, ±15 kV air) and 8/20 µs surges. |
| 2 | ANODE | passive | Anode of the unidirectional TVS/ESD protection diode (VRWM 5 V), protecting the one line it is connected to against ESD (IEC61000-4-2 ±8 kV contact, ±15 kV air) and 8/20 µs surges. |
