UBD32C05L01 from Brightking, 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 | 1 | passive | Terminal 1 of the single-line ESD protection diode (protects one I/O line, 5V working voltage); the datasheet text does not state its polarity or function. |
| 2 | 2 | passive | Terminal 2 of the single-line ESD protection diode (protects one I/O line, 5V working voltage); the datasheet text does not state its polarity or function. |
