SP0402U-ULC-01ETG from Littelfuse, in a DFN1006-2. 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 | Pin 1 of the 0402 DFN bottom view; the datasheet gives no individual function, polarity, or electrical limit for this pin, only the shared unidirectional/bidirectional pinout figure. |
| 2 | 2 | passive | Pin 2 of the 0402 DFN bottom view; the datasheet gives no individual function, polarity, or electrical limit for this pin, only the shared unidirectional/bidirectional pinout figure. |
