SP0402U-ELC-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 | Terminal 1 of the unidirectional 0402 DFN TVS diode (SP0402U-ELC-01ETG), rated for ±22kV IEC 61000-4-2 contact and air ESD with 0.30 pF typ input capacitance; the text does not state its polarity or function relative to pin 2. |
| 2 | 2 | passive | Terminal 2 of the unidirectional 0402 DFN TVS diode, rated for ±22kV IEC 61000-4-2 contact and air ESD with 0.30 pF typ input capacitance; the text does not state its polarity or function relative to pin 1. |
